For achieving the above object, the technical solution of the utility model is: a kind of automobile 1/4th suspension property testing tables, and this testing table is that two support posts are bolted on the ground frid by geosyncline, upper plate connects two support posts and forms the testing table outside framework; The inboard of two support posts all is equipped with guide rail and is connected by entablature; The ground frid of entablature below is provided with actuating vibration table, and this actuating vibration table is held tire, and the suspension top that tire connects is affixed to the center of entablature.
Be fixed with the mass of simulated suspension sprung mass on described entablature, simulate the sprung mass piece.
The lower end of described suspension is connected to guide rail by steering knuckle, brake flange, lower swing arm and sill successively; Be fixed with simulation unsprung mass piece on described sill.
Described sill uses ball stud to be connected with lower swing arm by groove.
Described entablature and its two ends slide block are set to integrative-structure and are fixed on by guide rail on two support posts of testing table; Described sill and one end slide block are set to integrative-structure and are fixed on by guide rail on a support post of testing table.
Described actuating vibration table is vertically fixed on the ground frid.
A kind of automobile 1/4th suspension property testing tables, owing to adopting above-mentioned structure, the utility model has the advantage of: 1, can meet automobile wish-bone arm type suspension system, Multi-link suspension system, the simulated condition experiment of McPherson strut system; 2, both can analyze the performance of single vibroshock, can analyze the suspension overall performance again; 3, more press close to the actual conditions of Vehicular vibration; 4, whole test platform structure is simple, stable, mechanical friction is little; 5, sprung mass separates consideration with unsprung mass, has improved the precision of experiment.

Embodiment
Below contrast accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1: support post 9 is arranged on ground frid 10 by foot bolt 15, and actuating vibration table 3 is vertically fixed on ground frid 10 by bolt.Two support posts 9 and upper plate 6 form the framed structure of testing tables, with bolt, fix.Vertical line slideway 11 is fixed on the both sides of testing table support post 9 by nut.Simulation sprung mass piece 7 is fixed by bolts on entablature 1 by screw, and entablature 1 is integrated with its two ends slider designs, and directly with guide rail 11, is connected.
While doing the actual condition experiment, first according to the automotive suspension design theory, determine sprung mass, suspension damping, suspension rate, the isoparametric initial value of non-suspension rate, the air pressure of regulating tire 12 meets the initial experiment value, will simulate sprung mass piece 7 and be fixedly connected with sill 2 with entablature 1 respectively with simulation unsprung mass piece 8.Suspension 5 test specimens are arranged on actuating vibration table 3.By the to-and-fro movement of HYDRAULIC CONTROL SYSTEM hydraulic cylinder rod member, the accumulation signal that output is set is simulated actual pavement behavior, the motion of actuating vibration table 3 passes to vehicle tyre 12 and suspension 5, the vibroshock of suspension 5 and spring assembly are with vibration drawing and compression, entablature 1 moves along guide rail 11 together with simulation sprung mass piece 7, lower swing arm 4 drives sill 2, makes sill 2 and simulation unsprung mass piece 8 fixed thereon move along guide rail 11.
