Abstract

The invention provides vehicle body testing and loading equipment. The vehicle body testing and loading equipment includes suspension devices, a loading device and displacement detection devices, wherein the suspension device is used for suspending a vehicle body to be tested; the loading device is connected with the vehicle body so as to pressurize the vehicle body; and displacement detection devices are connected with the vehicle body so as to detect the deformation of the vehicle body. The vehicle body testing and loading equipment can solve the problem that vehicle body testing and loading equipment in the prior art is not convenient for loading and testing a suspension train.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a vehicle body testing loading device. Background technique [0002] At present, there is an essential difference between the suspended sky train and the traditional vehicle structure in the past. The running part of this type of vehicle is located on the upper part of the car body, and the vehicle is suspended on the lower part of the running part through a track at a certain height from the ground. When a vehicle model is tested, it is first necessary to suspend the vehicle in the air, so the traditional longitudinal load test bench and loading device cannot be used to carry out longitudinal load loading on the vehicle. [0003] In addition, building a test bench is time-consuming, laborious, expensive and has a low utilization rate, and the construction of a pit is obviously a huge project. Contents of the invention [0004] The main purpose of the present invention is to pro...
