Abstract

The invention provides a method of processing kinematic characteristic data and dynamic characteristic data of an automobile suspension. The method comprises the steps: acquiring simulation documents and experimental documents of simulation and experimental tests under different work condition items; importing the acquired simulation documents and experimental documents into MATLAB (matrix laboratory) and extracting simulation data and experimental data from the MATLAB; acquiring simulation curves and experimental curves, capable of reflecting K&C characteristics of the suspension, of multiple work condition items and acquiring zero-point values or zero-point gradient values of the corresponding parameters; generating a K&C characteristic parameter table according to the calculated zero-point values or zero-point gradient values; and generating a report document according to the data processing result. Problems of consuming long time and making mistakes easily for obtaining the suspension performance analysis report can be solved well; the researching efficiency of the suspension performance of a simulation model or a trial vehicle at the automobile development and design stage can be improved greatly and the development cost is saved.

Description

technical field [0001] The invention relates to the field of automobile chassis, in particular to a method for processing data of automobile suspension kinematics and dynamics. Background technique [0002] The kinematics characteristics (Kinematics, referred to as K characteristics) and dynamic characteristics (Compliance, referred to as C characteristics) of the suspension are collectively referred to as the K&C characteristics of the suspension. When the forces and moments act, the suspension guide mechanism affects the performance of the vehicle. [0003] The K&C characteristic of the suspension is an important basis for the dynamic characteristics of the vehicle, which affects the overall vehicle performance such as vehicle handling stability, driving comfort and driving speed. There are two test methods: one is the computer software simulation method, and the other is the real vehicle bench test through the vehicle suspension test bench. Through the analysis and impr...
