The invention relates to the technical field of rolling testing, and discloses a rolling testing device and a testing method thereof. The rolling test device comprises: a test platform; a driving assembly which is arranged on the test platform; a transmission assembly which comprises a length-adjustable connecting arm, wherein the center of the connecting arm is in transmission connection with the output end of the driving assembly, and the driving assembly can drive the connecting arm to rotate in the horizontal plane; two load-carrying assemblies which are arranged at the two ends of the connecting arm correspondingly, wherein each load-carrying assembly comprises a weight with the adjustable weight; and two rolling parts, wherein each rolling part is rotatably arranged on one load-carrying assembly, the connecting arm can drive the load-carrying assemblies and the rolling parts to do circular motion in the horizontal plane, and the rolling parts rotate in the vertical plane relative to the load-carrying assemblies, so that the rolling parts roll a to-be-tested part on the test platform. The rolling test device disclosed by the invention can realize automatic rolling of the to-be-detected part, and has the characteristics of uniform rolling speed, high test accuracy and high test speed.
Description
technical field [0001] The invention relates to the technical field of rolling test, in particular to a rolling test device and a testing method thereof. Background technique [0002] In the prior art, in order to verify the reliability of the ground coil of the wireless charging system after the vehicle is rolled, the test is mainly carried out through real vehicle rolling. Due to the thousands of times of rolling, the test cycle is long, the tester needs to drive forward and backward repeatedly, and manual counting is required, the test efficiency is low, and the probability of error is high; at the same time, the speed of vehicle rolling cannot be accurately measured, which does not meet the test requirements. Contents of the invention [0003] Based on the above, the object of the present invention is to provide a rolling test device and its testing method, which can realize automatic rolling at a constant speed of the object to be tested, without manual counting, and ...
