Pickup truck rear door fatigue endurance performance test device, control system thereof and test method thereof

Abstract

The invention relates to a pickup truck rear door fatigue endurance performance test device, a control system thereof and a test method thereof. The test device comprises a rack composed of beams and stringers, a test bench and a turnover mechanism. The beams and the stringers are mutually connected. The test bench and the turnover mechanism are arranged at the end part of the rack. A turnover drive electric cylinder is arranged between a turnover vertical rod and a vertical bracket. A connection mechanism which is connected with a rear door is arranged on a turnover cross rod. According to the invention, the design is improved; the action of the operation of the pickup truck rear door and the force magnitude of a user can be truly simulated; fatigue endurance testing can be carried out on various pickup truck models sold in the current market; and the reliability of a rear door system can be effectively detected.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a pickup truck rear door fatigue durability testing system. Background technique [0002] With the continuous development of the automobile industry, automobile equipment has entered the era of flexibility, and the quality requirements for vehicles are getting higher and higher. Before a car goes on the market, all parts of the car need to be tested for functional compliance. As a practical tool that can take a small number of passengers and load goods, a pickup truck plays an irreplaceable role in the automotive field. And there are some defectives at present for the fatigue durability test of the rear car door parts on the pick-up truck, such as mentioned in CN104458279A in relevant automobile four-door two cover durability test performance system to carry out fatigue durability test to each door of common car, and this There are certain shortcomings in the durability ...

AI Technical Summary

Problems solved by technology

And there are some defectives at present for the fatigue durability test of the rear car door parts on the pick-up truck, such as mentioned in CN104458279A in relevant automobile four-door two cover durability test performance system to carry out fatigue durability test to each door of common car, and this There are certain defects in the durability test of the equipment for the special rear door of the pickup truck

Due to the high frequency of durability of the back door of pickup trucks, the durability of the equipment itself is also evaluated. If the equipment is unreliable, the reliability of the door system and the matching performance of related functional parts cannot be effectively tested.
