The test table adopts a motor (1) as a shock excitation power source, wherein the motor (1) is arranged above a test table beam (2) and connected with a straight rod (4) through a transmission system (3). The straight rod (4) vertically penetrates through the beam (2), a force sensor (5) is fixed on the straight rod (4), a displacement sensor is connected with the rear shock absorber (7), a horizontal rod (8) is vertically connected with the rear shock absorber (7), and a weight rod (9) is vertically connected with the horizontal rod (8) and downwards perpendicular to the ground. The test table adopts a mechanical excitation structure and mechanical uploading lateral force, is simple in structure and easy to control, and brings convenience to performance tests.
Description
Technical field
The present invention relates to be used to test the equipment of vibroshock performance, be specifically related to a kind of testing table that rear shock absorber is tested.
Background technology
The vibroshock testing table is the testing equipment that detects to the shock-absorbing capacity in the vehicle shock absorber operational process, and test findings can directly be checked out the good ring of vibroshock performance, is the indispensable test detecting equipment of support vehicles safe reliability.In test, reply vibroshock one end applies standard simple harmonic motion excitation, and that detects vibroshock on this basis shows merit characteristic, velocity characteristic etc.At present the energisation mode of vibroshock testing table has two kinds of hydraulic exciting and mechanical excitings, and exciting is to force vibroshock to be in certain duty.Hydraulic exciting formula vibroshock testing table servo apply hydraulic pressure oil cylinder is as excitation power source, and the shortcoming that this testing table exists is: noise is big, cost an arm and a leg, and the difficulty of control system relative complex, control is big.And mechanical excitation type vibroshock testing table is to be power source with the motor, and control is simple, through regulating motor speed with regard to the scalable excited frequency.
Rear shock absorber is the weight that is used for supporting vehicle frame, relaxes vibration and the impact of road injustice to motorcycle, and damped vibration rapidly, improves the comfortableness of riding, and lowers the dynamic stress of car body each several part, prolongs vehicle service life.But when curve passing through goes; Can cause the lateral force of vibroshock; The friction force that the vehicle shock absorber lateral force is produced can be quickened inner body wearing and tearing, like piston ring, piston rod, cylinder barrel etc., behind the parts wear in vibroshock each friction part produce " in let out the slit "; Thereby the initiation internal leakage causes the leakage of oil of vibroshock easily.The permanance that side force that vibroshock is suffered and consequent friction are not only indicating original paper, and influence the ride comfort of car load more directly, more significantly.
Therefore, in the vibroshock performance test, whether side force applies finding that the early stage problem of vibroshock plays crucial effects, and the selection that side force applies standard is again a gordian technique in the vibroshock test.By road excitation wheel is act as phase step type and be displaced sideways consideration; Vibroshock lateral force form is a constant force; Apply constant side force through testing table to vibroshock; Study the situation of friction force, thereby can judge the quality good or not and the reasonable structure of each friction part wear part, material in the vibroshock in early days.The servo-drive systems of fluid pressure type that adopt apply side force more in the vibroshock testing table at present, and the leakage of oil situation can take place complex structure.
Summary of the invention
The purpose of this invention is to provide a kind of mechanical type rear shock absorber property test platform, simple in structure, and can load side force easily to vibroshock to different automobile types.
For realizing the foregoing invention purpose, the present invention adopts following technical scheme:
The rear shock absorber property test platform adopts motor as excitation power source, and said motor is installed in the top of crossbeam; And be connected with straight-bar through kinematic train, said straight-bar vertically passes crossbeam, and force transducer is fixed on the said straight-bar; Displacement transducer is connected with rear shock absorber; Cross bar is connected with rear shock absorber is vertical, and the arm beam of steelyard is connected with said cross bar is vertical, and ground downward vertically.
Testing table of the present invention adopts mechanical excitation structure, and can mechanically apply side force to rear shock absorber, has advantages such as simple in structure, that control is convenient, is convenient to the experimental study of performance test.
Description of drawings
Fig. 1 is the structural representation of testing table of the present invention.
Fig. 2 is the right flank synoptic diagram of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done explanation in further detail.
As shown in the figure, testing table of the present invention comprises base, crossbeam 2, cross bar 8, column etc., and motor 1 is positioned at the top of crossbeam 2, and straight-bar 4 vertically passes crossbeam 2, and is connected with motor 1 through kinematic train 3.Kinematic train 3 comprises pinion wheel, gear wheel and driving belt.
During test, rear shock absorber 7 is installed on the testing table, as required, on the arm beam of steelyard 9, loads and claim stone roller.Drive straight-bar 4 by motor 1 then, and slowly descend along the axis direction of straight-bar 4, piston rod is slowly pressed down (from the free travel state to the minimum stroke state), the minimum speed that moves can reach 0.005m/s.Be transferred in the computer through force transducer 5 and the power variation and the change in displacement of displacement transducer 6, test images described out by trace routine with this process.
Testing table of the present invention can through changing the weight of sliding weight of steelyard, apply different side forces to vibroshock, thereby can measure the friction force of vibroshock according to different vehicles.
Claims (2)
1. rear shock absorber property test platform; Adopt motor (1) as excitation power source, it is characterized in that: said motor (1) is installed in the top of crossbeam (2), and is connected with straight-bar (4) through kinematic train (3); Said straight-bar (4) vertically passes crossbeam (2); Force transducer (5) is fixed on the said straight-bar (4), and displacement transducer (6) is connected with rear shock absorber (7), cross bar (8) and vertical connection of said rear shock absorber (7); The arm beam of steelyard (9) and vertical connection of said cross bar (8), and ground downward vertically.
