Abstract

The invention discloses a vehicle body structure optimization method and system, and the method comprises the steps: obtaining a suspension physical structure of a vehicle body, and building a multi-body dynamics model according to the suspension physical structure; Analyzing the movement condition of the wheel along with the suspension frame through multi-body dynamics simulation software, and adjusting the movement condition of the wheel according to the sensitivity of a suspension frame part; The main bushing characteristics of the suspension are adjusted, so that the bushing absorbs more impact energy from the wheel. According to the method, the motion characteristics of the suspension mechanism can be determined through multi-body kinematics analysis in the design stage; The bushing structure is redesigned according to the vehicle parameter information, the existing suspension structure can be used to a great extent in the chassis development process, the universality of parts isimproved, the chassis development and optimization cost is effectively reduced, and the vehicle performance can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for optimizing a vehicle body structure. Background technique [0002] With the rapid development of the economy and the automobile industry, people's living standards have been rapidly improved, and automobiles have gradually become the means of travel for ordinary families. [0003] When people drive a car, they often encounter some roads with poor road conditions, such as potholes, gravel, etc. When the car is driving on these roads, the ride comfort of the vehicle will be greatly affected, especially when the speed is high , the driver and passengers will receive a greater impact, affecting the driving and riding experience. [0004] Therefore, in the process of vehicle development, it is necessary to improve the ride comfort of the vehicle. However, due to the relatively old suspension technology used in some models, when optimizing the body structur...
