Suspension and plate spring motion analysis method and system

Abstract

The invention discloses a suspension and plate spring motion analysis method and system, and the method comprises the following steps: carrying out the segmented simulation of a plate spring, and obtaining a plate spring equivalent model; calculating data parameters of the plate spring equivalent model; obtaining a dynamic simulation hard point skeleton-level model of the suspension; and inputtingthe data parameters of the plate spring equivalent model and preset suspension dynamic parameters into the dynamic simulation hard point skeleton-level model to obtain kinematic characteristic data corresponding to the suspension and the plate spring. According to the method and system, the plate spring can be simplified into the plate spring equivalent model, so that the plate spring is combinedwith the whole suspension mechanism, dynamic simulation of a whole suspension system is achieved, high-similarity plate spring motion simulation is achieved, dynamic analysis of suspension inclination bounce can be achieved, and a guiding effect on design of peripheral parts of the front portion is achieved.

Description

technical field [0001] The invention relates to the field of dynamic analysis of automobile design suspension systems, in particular to a suspension and leaf spring motion analysis method and system. Background technique [0002] At this stage, there are few studies on suspension and leaf spring kinematics simulation in the industry. Traditional leaf spring trajectory methods, leaf spring parametric modeling and other analysis methods cannot combine leaf springs with the entire suspension mechanism. As a result, it brings certain difficulties to the integrity of the dynamic analysis of the suspension system and the subsequent boundary setting, and cannot play a relevant guiding role in the design of the front peripheral parts. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] For this reason, an object of the present invention is to propose a kind of suspension and leaf spring ...
