Problems solved by technology

The resonance method test bench is divided into force-measuring type and displacement-measuring type according to different detection parameters. The vibration curve of the force or displacement during the attenuation process is used to obtain the frequency and attenuation characteristics to judge the performance of the suspension. The existing suspension test bench cannot completely simulate the road conditions, and the suspension performance tested by it can only reflect the performance of the suspension. The performance of the suspension under certain characteristic conditions cannot truly and completely test the performance of the suspension

Abstract

The invention belongs to the vehicle test apparatus field and especially relates to a six-dimensional parallel-connection test bench for an automobile suspension test. The six-dimensional parallel-connection test bench comprises a support rack for installing a suspension. The suspension is arranged on the support rack and is connected with wheels, a suspension spring and a damper. A road-condition simulation apparatus is connected below the wheels and comprises a bearing installation plate and a simulation plate, wherein the simulation plate is contacted with the wheels. A six-dimensional parallel mechanism is connected between the simulation plate and an installation plate. The road-condition simulation apparatus also comprises a position detection mechanism, wherein the position detection mechanism is fixed on the installation plate, is used for detecting motion quantity of the simulation plate, is connected with the bottom of the simulation plate and is provided with a triaxial gyroscope for detecting an inclination angle of the simulation plate. Pull and pressure sensors for detecting a bearing condition of the suspension and suspension displacement sensors for detecting change quantity of the suspension spring and the damper are mounted on the top of the suspension spring and the damper. A load mechanism is disposed on the top of the support rack and is connected with the suspension spring and the damper.

Description

technical field [0001] The invention belongs to the field of vehicle testing devices, and in particular relates to a six-dimensional parallel test bench for automobile suspension testing for simulating road conditions to test suspension performance. Background technique [0002] The automobile suspension device is an important assembly of the elastic connection between the automobile body and the wheel, and usually consists of three parts: elastic elements, guiding devices and shock absorbers. When the car is running, the car vibrates due to the uneven road surface. When the car vibrates to a certain extent, the occupants will feel uncomfortable and fatigued, which will affect the handling stability of the car. At the same time, the changing load will also reduce the service life of parts. As an important part of the chassis platform, the suspension and steering system of an automobile is directly related to the handling stability, steering portability, and tire life of the ...
