Abstract

A sunken obstacle for wheel simulation live impact test, consisting of a sunken obstacle block (1), a triaxial force sensor (2), a sensor base (3) and a groove (5), characterized in that: The groove (5) is located on the test road surface (4); the sensor base (3) is placed on the bottom of the groove (5); one end of the triaxial force sensor (2) is installed on the upper surface of the sensor base (3), and the other One end is installed on the lower surface of the recessed obstacle block (1); the cross-section of the recessed obstacle block (1) along the length direction of the groove (5) has a trapezoidal depression; and, the recessed obstacle block (1) It is set that after the installation is completed, the bottom edge of the depressed trapezoid is flush with the road surface (4). The sunken obstacle of the present invention has the advantages of simple structure, sensitive detection and the ability to well simulate the influence of various sunken obstacles on the road surface on the wheels.

Description

technical field [0001] The invention relates to the field of simulation tests of auto parts, in particular to a sunken obstacle used for a wheel simulation live impact test. Background technique [0002] At present, when carrying out the simulated impact test of wheels, the bench method is often used to carry out tests such as radial impact and 13-degree impact, so as to examine the reaction of the wheel under various impact conditions and determine whether the wheel meets the requirements of automobile manufacturers and users. . [0003] The bench test is a simulation of real driving conditions, and the simulation results may not fully reflect the real reaction to various unideal road surfaces in the actual driving process. In order to provide vehicle quality under traffic accident conditions, vehicle manufacturers often use tests such as a real car crashing into a wall to examine the performance of the vehicle under traffic accidents. However, there is no method and devi...
