Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0031] like figure 1 Shown, passenger car structural optimization method of the present invention comprises the steps:

[0032] S1. Establish the initial model of the beam unit of the whole vehicle, conduct modal analysis on it, and compare it with the modal of the same type of vehicle.

[0033] Among them, the comparison with the modes of the same type of vehicles is carried out in order to realize the validity of the verification model.

[0034] S2. According to the comparison results, a topological shell element model is esta...

Abstract

The invention provides a method for optimizing the structure of a passenger car. The method for optimizing the structure of a passenger car can reduce the weight of a traditionally designed passenger car by 30%, and increase the stiffness of the entire vehicle by 20%. The stress distribution of the entire vehicle is even and there is no stress concentration area, while meeting the requirements of lightweight, improve the safety performance of the vehicle. At the same time, the bus structure optimization method of the present invention can significantly reduce the development cycle of the whole bus and reduce the cost of the bus.

Description

technical field [0001] The invention relates to the technical field of passenger cars, in particular to a method for optimizing the structure of passenger cars. Background technique [0002] In the skeleton design of a bus, the body skeleton of a bus is different from that of a car. The body structure of a bus is mainly welded by square steel of different specifications. In design, the traditional bus skeleton design is mainly based on design experience, which puts forward higher requirements on the professional skills of engineers. When it is necessary to modify the skeleton structure of the bus, it needs to be verified by tests, and the design period is long. [0003] Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0004] The purpose of the present invention is to provide a passenger car structure optimization method to overcome the problems in the prior art. [0005] In order to realize the above-me...
