The fixing plate of the rear end of the brake waveshape monitor is fixed on the ground. Cross beams of both sides are fixedly connected with a steel cylinder. Both sides of the steel cylinder are respectively fixedly connected with two reinforcing ribs. The inner cavity of the steel cylinder is filled with hydraulic-oil. The left end of the waveshape control lever is fixed and the right end is sliding and contacts the inner cavity of the plunger. The plunger is sliding and connected with the inner cavity of the steel cylinder. The left end of the plunger is an impact surface and the right end is equipped with a flow hole. A sliding table platform is rolling and contacts the ground through balls. The sliding platform is fixed with a BIW fixedly connected with a control board, a steering wheel, a safety air bag, a ladder belt, an armchair seat of front row and a dummy 8 according to the position of a real automobile. The advantage are as follows: the structure is novel and simple, the use method is visual, the utility model has the same testing direction as an automobile, and the comprehension is easy. The utility model can make the platform simulate a dynamicsprocess in collision process under any collision mode of an automobile.
Description
Technical field
The utility model belongs to a kind of vehicle passive safety pilot system.
Background technology
The purpose of trolley impact test is to reappear the dynamic process of full scale vehicle collision, generally estimates the chassis precision of trolley impact test with the repeatability of acceleration/accel time history curve in trolley impact test and the real vehicle collision test.The trolley impact pilot system can be divided into two types of brake type and emission-types by using method:
1) emission-type trolley impact pilot system
To motion, acceleration direction is towards occupant's behind by static for slide platform in the emission-type trolley impact pilot system.HYGE is a kind of representative type emission-type test cell, adopts high pressure gas as propulsion source, changes by the gauge needle appearance profile and realizes the fluid resistance transient control, thereby realize the chassis of slide platform acceleration/accel waveform control.Another kind of emission-type chassis is a hydraulic efficiency servo, and the synchronized movement of piston and slide unit adopts the transient state aperture of system controlled by computer servovalve, adjusts the pressure of back pressure oil pocket, gets final product the characteristics of motion of control plunger.
2) brake type trolley impact pilot system
The brake type table system is after allowing slide unit reach certain speed earlier slide unit to be braked, and the decelerating phase of braking is a test section, and the dynamic process of deceleration is to be controlled by the rear end waveshape monitor that plays the drg effect.Throttling cellular type hydraulic pressure waveshape monitor is a kind of common brake structure, has a series of cutoff port on the cylinder barrel surface, and when piston moves in cylinder barrel, the liquid working substance in the high pressure chest will spray outside the chamber by cutoff port.The variation of the number of cutoff port changes orifice size in the motion process, thereby changes the back pressure resistance of piston.By adjusting the arrangement aperture of each cutoff port, can reach the purpose that realizes different acceleration/accel waveforms.Another kind of brake type chassis adopts energy-absorbing material to brake.Energy-absorbing material formula waveshape monitor uses the section bar rigidity of being clashed into to come the control wave waveform, such as the stiffness characteristics of simulating real vehicle with one group of reinforcing bar or steel plate.
The ubiquitous problem of above-mentioned trolley impact pilot system is: cost and maintenance cost are higher, the need high pressure accessory equipment that has, and relocation equipment is not easy.
Summary of the invention
The utility model provides a kind of automobile front trolley impact experimental set-up, and is higher to solve present trolley impact pilot system ubiquity cost and maintenance cost, and relocation equipment such as is not easy at problem.The technical scheme that the utility model is taked is: mainly comprise two parts, the one, the slide platform system, the 2nd, braking Waveform Control system, braking waveshape monitor rear end adapter plate 1 fixes on the ground, both sides crossbeam 2 is captiveed joint with steel cylinder 4, these steel cylinder 4 each captive joints of both sides two reinforced ribs 3, these steel cylinder 4 inner chambers are full of hydraulic oil, Waveform Control bar 5 left ends are fixed, right-hand member and piston 6 inner chamber moving contacts, piston 6 and steel cylinder 4 inner chamber sliding block joints, piston 6 left ends are shock surface, right-hand member has fluid hole; Slide unit platform 10 contacts with ground surface by ball 9, and fixing body in white 7 on the slide platform 10 is pressed real vehicle stationkeeping connection instrument carrier panel, steering handwheel and safety air bag, safety strap, front-row seats and dummy 8 on the body in white 7.
Waveform control stalk 5 its outer contours become irregular curve according to concrete chassis Waveform Design before the test, piston 6 stretches out fully, be positioned at steel cylinder 4 low order ends, at this moment, piston 6 is divided into two chambeies with steel cylinder 4, high pressure chest and low-pressure cavity, slide platform 10 is static, and with waveshape monitor certain distance is arranged, use the general-duty tractor equipment, as the spring rope, DC machine etc. are after traction slide platform 10 reaches specified speed, slide platform 10 impact pistons 6 right-hand member striking faces, and promote piston 6 and continue together to left movement, piston 6 moves in the chamber, and high pressure chest liquid flows to low-pressure cavity by fluid hole; Because Waveform Control bar 5 outlines constantly change, therefore, in piston 6 moves, constantly change at the suffered liquid resistance of diverse location, thus the purpose of realization control plunger 6 and slide unit system 10 acceleration of motion.
Advantage of the present utility model is: novel structure is simple, and expense is low; Using method is directly perceived, and is identical with the real train test direction, easy to understand.The rear end waveshape monitor is a collision energy transient process controller, can make platform simulate dynamic process under any one full scale vehicle collision mode at collision process.

The specific embodiment
Braking waveshape monitor rear end adapter plate 1 fixes on the ground, both sides crossbeam 2 is fixing with steel cylinder 4, for guaranteeing steel cylinder 4 secure fixation, in steel cylinder 4 both sides two reinforced ribs 3 have been installed respectively, steel cylinder 4 inner chambers are full of hydraulic oil, and Waveform Control bar 5 left ends are fixed, right-hand member and piston 6 inner chamber moving contacts, piston 6 is free to slide about can be in steel cylinder 4, and piston 6 left ends are shock surface, and right-hand member has fluid hole; Slide platform 10 contacts with ground surface by ball 9, slide platform 10 can left and right sides free motion, fixing body in white 7 on the slide platform 10 is equipped with instrument carrier panel, steering handwheel and safety air bag, safety strap, front-row seats and dummy 8 by the real vehicle position on the body in white 7.
