Electro-hydraulic servo cylinder large platform test bench for vehicle guardrail test

Abstract

The invention relates to an electro-hydraulic servo cylinder large platform test bench for a vehicle guardrail test. The electro-hydraulic servo cylinder large platform test benchincludes a guardrail test bench basic part assembly body (1), a pressure applying three-coordinate sliding table assembly body (2), a guardrail counter-force gantry frame assembly body (3), a counter-force seat (4), a hydraulic pump and synchronous motor assembly body (5), a stroke actuator assembly body (6) and an unbalance loading resisting guide rail and piston rod assembly body (7). The hydraulic pump and synchronous motor assembly body (5) is connected with the stroke actuator assembly body (6) through a hydraulic pipeline, and the stroke actuator assembly body (6) drives the unbalance loading resisting guide shaft frame assembly body (45) in the unbalance loading resisting guide rail and piston rod assembly body (7) to do linear motion back and forth, so that loading of a test piece is realized. The technical problem to be solved by the invention is to make up the technical vacancy of the test bench for the vehicle guardrail test at the present stage and meet the technical requirements of related national standards.

Description

technical field [0001] The invention relates to a vehicle guardrail test stand, more specifically, the invention relates to a vehicle guardrail test electro-hydraulic servo cylinder large platform test stand. Background technique [0002] With the rapid development of my country's automobile industry, especially the great progress of large-scale commercial vehicles, the demand for commercial vehicles in the market is increasing rapidly. At the same time, traffic accidents caused by commercial vehicles are increasing. Vehicle safety has always been a topic of concern to all sectors of society. . The damage, loss and casualties caused by the side collision of commercial vehicles are extremely serious. Small cars do not have side rails, and serious injuries and fatalities can easily occur when the car is hit from the side. For a large truck, when a small car hits from the side, if there is no side guardrail, the small car is easy to get into the bottom of the truck and get stu...

AI Technical Summary

Problems solved by technology

Therefore, in order to effectively protect and prevent or mitigate such side collision accidents, the research and design of commercial vehicle side guardrails have become the focus in recent years. At the same time, the test methods and technical requirements for commercial vehicle side guardrails also need to be further improved. There are still technical vacancies in the side guardrail test bench that meets the national standards at the stage
