Method for processing Kinematics and Compliance characteristic data of sedan suspension

Abstract

The present invention provides a method for processing Kinematics and Compliance characteristic data of a sedan suspension. The method comprises: acquiring emulation files and experimental files, which are obtained by performing emulation and experiment tests in different working condition projects; acquiring names of all the files in each working condition project, and storing the file names in the same working condition projects in the same file name storage units; reading the file name storage units, importing the emulation files and the experimental files in the corresponding working condition projects into a MATLAB according to the file names, and extracting emulation data and experimental data; acquiring an emulation curve and an experimental curve of a plurality of working condition projects that reflect Kinematics and Compliance characteristics of the suspension, and generating a Kinematics and Compliance characteristic parameter table; and generating a report file according to a result of data processing. According to the method for processing the Kinematics and Compliance characteristic data of the sedan suspension, the names of all the emulation files and experimental files in each working condition project can be simultaneously obtained, so that data of the files of the plurality of working condition projects can be processed all at once subsequently, time is saved, an error rate is low and further the development cost is saved.

Description

technical field [0001] The invention relates to the field of automobile chassis, in particular to a processing method for car suspension K&C characteristic data. 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 experimental 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 improvement...
