Abstract

The invention provides a test bench which comprises a main machine and a binding component, wherein the main machine comprises a swinging component and an overturn system; the swinging component comprises a swinging plate capable of swinging freely in forward and backward directions; the overturn system is arranged on the swinging plate, and is used for driving an object to be tested to turn over, and/or rotate in a horizontal plane; the main machine further comprises a leveling system used for adjusting the swinging plate so as to enable the swinging plate to return to an equilibrium position under a force-free effect; the binding component is arranged on the overturn system and used for fixing the object to be tested; the test bench further comprises an angle gauge used for measuring the inclination angle of the swinging plate and a period meter used for testing the swing period of the swinging plate. The test bench provided by the invention can be used for measuring more parameters, the measuring process is short, and the efficiency is high.

Description

technical field [0001] The invention relates to a test bench, in particular to a bench for testing the center of mass and moment of inertia of a rigid body. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, people have obviously higher requirements for the quality of life. For example, the change of transportation, from the first walking to the bicycle era, and then slowly transitioning from the bicycle era to the motorcycle era, and now more and more cars have entered the homes of ordinary people and become an indispensable means of transportation for people. . [0003] For a passenger car, the height of its center of mass directly affects the roll and pitch performance of the passenger car; its moment of inertia directly affects the vehicle's transient handling stability; moreover, parameters such as the center of mass and moment of inertia of the car are determined during the simulation analysis proc...
