Method and system for designing stabilizer bar of automotive suspension

Abstract

The invention discloses a method for designing a stabilizer bar of an automotive suspension. The method comprises the steps of: (a) setting the installing position of the suspension stabilizer bar and the length and position data of a connecting rod according to predefined shapes and installing positions of all parts of the automotive suspension; (b) building a DMU model according to the set data to generate motion envelopes; (c) laminating the motion envelopes to obtain a maximum value, setting the shape of the suspension stabilizer bar, and obtaining a gap between the suspension stabilizer bar and the maximal motion envelope; (d) judging if any value of the obtained gap is greater than a predefined safety gap, if so, operating the step (e), if not, returning to the step (b) after resetting the installing position of the suspension stabilizer bar and the length and position data of the connecting rod; and (e) finishing the design. The invention further discloses a system for designing the stabilizer bar of the automotive suspension. The method and the system simplify the design steps of the suspension stabilizer bar, shorten the design period, and improve the shape design level of the suspension stabilizer bar.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for designing an automobile suspension stabilizer bar. Background technique [0002] Usually, in order to reduce the bias frequency of the car suspension to improve the ride comfort of the car, the vertical stiffness of the car suspension is designed to be relatively low, so that the roll angle stiffness of the car is also designed to be relatively low, causing the car to turn When a large body roll angle is generated, the stability of the car will be affected. In order to solve the above problems, the suspension stabilizer bar design is currently used on the front and rear suspensions of the car, and the ratio of the roll angle stiffness of the front and rear suspensions of the car is adjusted through the suspension stabilizer bar to obtain the required steering characteristics. [0003] In the suspension design process, the control arm, shock absorber a...
