Eight-channel multi-function suspension road simulation test bench

Abstract

The invention discloses an eight-channel multifunctional road simulation test bench, which is assembled by a suspension fixing system and a servo-hydraulic actuator fixing system. The suspension fixing system includes a suspension fixing base, a beam and a shock absorber fixing bracket. Base, shock absorber fixing bracket, spring fixing top rod, front body replacement plate, suspension fixing bracket, rear body replacement plate and four-degree-of-freedom loading arm, servo hydraulic actuator fixing system including suspension servo hydraulic actuator gantry , Vertical servo hydraulic actuator, lateral reaction force seat, lateral servo hydraulic actuator, longitudinal reaction force seat and longitudinal servo hydraulic actuator. The invention can perform eight-channel road simulation for the suspension system, and the four degrees of freedom on one side can respectively control the vertical force, lateral force, longitudinal force, roll moment and braking moment, not only can the suspension to be tested be tested on the road Simulation test, coordinated loading test can also be carried out according to actual needs, which can quickly and effectively realize the durability assessment of the suspension system.

Description

technical field [0001] The invention relates to an eight-channel multifunctional suspension road simulation test bench, in particular to a multifunctional road simulation test bench for carrying out eight-channel road simulation for a suspension system, that is, loading with four degrees of freedom on one side, and belongs to the durability of a suspension system. The field of sexual testing technology. Background technique [0002] Suspension system is one of the important components of the whole vehicle, so its durability test is paid special attention in the development process of suspension system. [0003] At present, the road simulation test of the suspension system is mainly carried out by the axle-coupled road simulation test bench, and the axle-coupled road simulation test bench is mostly a comprehensive test of the reliability of the whole vehicle. Insufficient resources, and it is necessary to design and manufacture fixed fixtures; the suspension system test usin...

AI Technical Summary

Problems solved by technology

[0003] At present, the road simulation test of the suspension system is mainly carried out on the shaft-coupled road simulation test bench, and the shaft-coupled road simulation test bench is mostly a comprehensive test of the reliability of the vehicle. Insufficient resources, and the need to design and manufacture fixing fixtures; the suspension system test using linear actuators is mainly based on one-way loading, and its failure mode is inconsistent with the actual failure mode, which cannot really play a role in testing products

[0004] At this stage, there is no test bench for the eight-channel road simulation test for the suspension system using a combination of discrete servo-hydraulic actuators
