The present invention is achieved through the following technical solutions：
A kind of string series connection capillary variable system intrinsic frequency vehicle shock absorber operation method, which includes vehicle Frame 11, axle 17 and hydraulic cylinder 13；The upper end of the hydraulic cylinder 13 passes through its piston rod connecting vehicle frame 11, the lower end of hydraulic cylinder 13 Cylinder body connects axle 17；Piston 15 in hydraulic cylinder 13 divides hydraulic cylinder 13 for upper bunker 14 and lower bunker 16；
On pipeline between 16 oil transportation mouth of the upper bunker 14 and lower bunker, it is connected with capillary series connection in turn from top to bottom Formula damping association section, capillary series system intrinsic frequency are associated with section；That is, the F hydraulic fluid ports of capillary tandem damping association section The E hydraulic fluid ports of the A hydraulic fluid ports of bunker 14 in connection, capillary tandem damping association section connect capillary series system intrinsic frequency The I hydraulic fluid ports of section are associated with, capillary series system intrinsic frequency is associated with the B hydraulic fluid ports of bunker 16 under the J hydraulic fluid ports connection of section；
Vehicle shock absorber operation method is that, when generating relative motion between vehicle frame and axle, piston can generate accordingly Or the movement of up or down, the capillary tandem that the oil-based liquid in hydraulic cylinder 13 can pass through between A hydraulic fluid ports, B hydraulic fluid ports at this time hinder Buddhist nun is associated with section and is associated with section with capillary series system intrinsic frequency, and then flows to lower bunker 16 from upper bunker 14, or under Bunker 16 flows to upper bunker 14；
Due to the viscous effect of the oil-based liquid in cylinder body, when oil-based liquid flows through capillary tandem damping association section When, capillary tandem, which damps the capillary to work in association section, to generate damping to the flowing of oil-based liquid, to formation pair The resistance of piston movement；The configuration S that the size of the resistance passes through solenoid valve by capillary control systemRnControl, and then realize hair The resistance trimming of tubule tandem damping association section；
When oil-based liquid, which flows through capillary series system intrinsic frequency, is associated with section, changed by capillary control system The configuration S of solenoid valvemn, then the system frequency of adjustable vibration-damper, and then realization capillary series system intrinsic frequency It is associated with the frequency modulation of section.
The capillary tandem damping association section includes four capillaries being sequentially connected in series, wherein per capillary Both ends are parallel with solenoid valve；The effect of the solenoid valve is to control the break-make of capillary.
The capillary series system intrinsic frequency association section includes concatenated four capillary；This four capillary is equal It is parallel with solenoid valve；The effect of the solenoid valve is to control the break-make of capillary.
Two interface ends of the capillary series system intrinsic frequency association section are respectively I hydraulic fluid ports, J hydraulic fluid ports.
Four capillary sectional areas of the capillary series system intrinsic frequency association section are equal.
The length ratio of four capillaries of the capillary series system intrinsic frequency association section is 8:4:2:1；I.e. Their length is arranged according to 8421 binary coding rule.
In four capillaries of the capillary series system intrinsic frequency association section, the diameter d of capillarymThan series connection The capillary diameter d of formula damping association sectionRIt is twice above.
The capillary tandem damping association section is associated with the capillary in section with capillary series system intrinsic frequency, Disk is at " M " word shape, serpentine shape or spiral-shaped.
The capillary tandem damping association section is associated with the solenoid valve in section with capillary series system intrinsic frequency Also it is connect with capillary control system；Capillary control system is used to control the break-make of each solenoid valve.
Spring 12 is equipped between vehicle frame 11 and axle 17.
The vehicle shock absorber operation method of the present invention is described further below：
When generating relative motion between vehicle frame and axle, piston can generate accordingly or the movement of up or down, at this time liquid Oil-based liquid in cylinder pressure 13 can pass through capillary tandem damping association section (the hereinafter referred to as resistance trimming between A hydraulic fluid ports, B hydraulic fluid ports Section) section (hereinafter referred to as frequency modulation section) is associated with capillary series system intrinsic frequency, and then flow to lower bunker from upper bunker 14 16, or flow to upper bunker 14 from lower bunker 16.
Due to the viscous effect of the oil-based liquid in cylinder body, when oil-based liquid flows through resistance trimming section, the capillary of resistance trimming section Damping can be generated to the flowing of oil-based liquid, to form the resistance moved to piston；The size of the resistance is controlled by capillary The configuration S that system passes through solenoid valveRnControl, and then realize the resistance trimming of resistance trimming section.
In damper according to damping requirements by the configuration S of resistance trimming sectionRnAfter deciding, damper is further according to intrinsic frequency It is required that the solenoid valve V that will determine frequency modulation sectionm8、Vm4、Vm2、Vm1Configuration Smn。SmnIn, the value range of n is 0,1,2 ..., 15； Wherein Sm0Indicate solenoid valve Vm8、Vm4、Vm2、Vm1Close All；Sm1Indicate Vm8、Vm4、Vm2、Vm1In only Vm1It is open-minded, remaining closing； Sm2Indicate only Vm2It is open-minded, remaining closing；Sm3Indicate only Vm2、Vm1It is open-minded, remaining closing.And so on Sm4To Sm15。
As the configuration S of frequency modulation sectionmnIt determines, then participates in the mass M of the fluid of oscillation in frequency modulation sectionmnAlso it determines that；To The quality that the fluid that oscillation carries out vibration damping is participated in damper is then MRn+Mmn(M hereinRnTo participate in the fluid of oscillation in resistance trimming section Quality).Compared with spring oscillator, mass MRn、MmnSynthesis quality then be similar to spring oscillator pellet quality；We are logical Cross change MmnTo change MRn、MmnSynthesis quality to change the intrinsic frequency of damper system.
Because the diameter of the capillary of frequency modulation section is all much larger than the diameter of the capillary of resistance trimming section, the pressure of frequency modulation section Head loss is just much smaller than the head loss of resistance trimming section.In this way, the damping of damper is exactly mainly the damping of resistance trimming section, it therefore, will Capillary tandem damping association section is also referred to as resistance trimming section.Again because of influence very little of the frequency modulation section to damping, and it can change Become the system frequency of damper, so, capillary series system intrinsic frequency association section is referred to as frequency modulation section.And because Also tandem capillary is used to adjust for the adjusting of resistance trimming section tandem capillary, frequency modulation section, so, this system is exactly string series connection hair (first " string " indicates that the working method of resistance trimming section is series system to tubule damper, and second " string " indicates the work of frequency modulation section It is series system as mode).
Because the diameter of the damping very little of frequency modulation section, frequency modulation section capillary is bigger, we can be easy to pass through The length of frequency modulation section capillary is lengthened by MmnIt is made and is much larger than MRn, so as to by the adjusting model of damper system intrinsic frequency It encloses and is made very big.
The resistance trimming section of damper, frequency modulation section tandem working, the state of resistance trimming section is by configuration SRnDetermine, the state of frequency modulation section by Configuration SmnIt determines；So the working condition of damper can be indicated with following table.
The theoretical work state table of damper：
Valued content in table above can be regarded to 16 × 16 matrix as, the element of the matrix is exactly (SRn, Smn).Therefore, the mode of the theoretical work state matrix of damper clearly and succinctly is illustrated out by the present invention, so this The system of invention is also referred to as a kind of vehicle shock absorber for capillary variable system intrinsic frequency of connecting for matrix-style serial.
The configuration S of each solenoid valve in resistance trimming section and frequency modulation sectionRn、SmnIt is controlled by the capillary control system of damper.
Because of the M of frequency modulation sectionmnAdjustable range it is very big, so the range that damper system intrinsic frequency changes is also very big； To solve the problems, such as that hydraulic buffer system frequency is non-adjustable or adjustable extent very little.
The present invention compared with the existing technology, has the following advantages and effect：
The configuration S that the present invention passes through change frequency modulation section solenoid valvemnIt is non-adjustable to solve hydraulic buffer system frequency Or the problem of adjustable extent very little.
Present inventive concept is ingenious, cheap, technological means is simple and easy to do.The present invention is constructed with simple mechanical structure Digitlization adjusts the executing agency of damper system intrinsic frequency, and by the mode of the theoretical work state matrix of damper Clearly and succinctly illustrate out；The quality for greatly improving the system frequency of hydraulic buffer, subtracts Hyundai Motor The development for technology of shaking has advantageous effect positive, outstanding.
