Abstract

A test method for testing ground pressure of a tracked vehicle includes the following steps: A. according to the number of loading wheels at one side of a tracked vehicle which needs testing, a corresponding number of holes are dug on the ground, all the holes are arranged in a row, and distance between adjacent holes equals to that between adjacent loading wheels at one side of the tracked vehicle; B. a ground pressure sensor is placed in each hole, each ground pressure sensor is numbered, a numbering sequence is that the ground pressure sensor located at one end is numbered as Number 1, the ground pressure sensor adjacent to the Number 1 ground pressure sensor is numbered as Number 2, the next ground pressure sensor adjacent to the Number 2 ground pressure sensor is numbered as Number 3, and according to this sequence, all the ground pressure sensors are numbered. The invention aims to provide a test method for testing ground pressure of a tracked vehicle, and the method can help researchers to accurately analyze ground tractive characteristics and steering performance of the tracked vehicle.

Description

technical field [0001] The invention relates to a method for testing ground contact pressure of crawler vehicles. Background technique [0002] When a tracked vehicle is running on the ground, the ground contact pressure distribution between the track and the ground is one of the important indicators of the overall performance of the tracked vehicle. At the beginning of the development of vehicle ground mechanics theory, because the ground contact pressure of tracked vehicles could not be obtained through experimental testing, researchers calculated the ground traction force of tracked vehicles by assuming that the distribution of track ground contact pressure was uniform or concentrated. , but the calculation results are quite different from the actual situation. [0003] In order to more accurately calculate the ground traction characteristics of tracked vehicles, foreign scholars have carried out experimental testing and research work on track ground pressure. In the art...
