Multifunctional testing platform of dynamic characteristics of vehicle dynamics

Abstract

The invention discloses a multifunctional testing platform of the dynamic characteristics of vehicle dynamics, which comprises a rotary coder, a synchronous belt, a moment motor, a retaining ring, a bearing, a motor slide block, a shaft sleeve, a longitudinal guide rail, a transversal guide rail, a fixed square plate, a steel ball, a steel ball fixing frame, a rotating disc, a moment sensor, a brake disc, a cylinder bracket, a cylinder shaft, an outer rotor motor, a force and moment sensor, an arrester bracket, an arrester, a cylinder, a measurement and control system, a code disc, a rotating speed sensor, a centering roller bracket, a centering roller lifter and a centering roller. By the invention, the whole vehicle dynamics is comprehensively researched on the testing platform, a driving or brake moment and a steering resisting moment are applied to wheels, and the wheels are permitted to steer in rotating motion so that more working conditions can be imitated by applying driving or braking moment on wheels and permitting the wheels to steer during rotating motion. The multifunctional testing platform can test and research the dynamic characteristics of vehicle longitudinal dynamics and transversal dynamics. The attached figure is the structural front view of the invention.

Description

technical field [0001] The invention relates to an automobile test bench, in particular to an automobile dynamic characteristic test bench. Background technique [0002] Vehicle dynamics mainly includes longitudinal dynamics, lateral dynamics and vertical dynamics. At present, the methods used in the testing and research of automobile dynamics mainly include real vehicle road test, computer simulation and bench test. The real vehicle road test requires a large test site, and the test cost is high. The computer simulation method needs to establish a mathematical model of the vehicle and its components, and requires experimental verification. The bench test method overcomes the shortcomings of the real vehicle road test and computer simulation method to a large extent, and is widely used in the test and research of automobile dynamics. However, the current automobile dynamics test bench uses longitudinal dynamics and vertical dynamics It mainly focuses on the testing and re...
