Auto - body assembly is one of important parts of the whole car . its quality is a key factor that affects the quality of the whole car 轿车车身是轿车的重要组成部分,是影响整车质量的重要因素之一。
The auto - body assembly requires hundreds of sheet metals . for accounting the effect of low stiffness of sheet metals , their tolerances based on analysis and synthesis have an influence on the quality of the assembly 轿车车身主要由冲压金属薄壁件组成,具有柔性大、刚度小等特点,其装配偏差的分析与综合对装配质量有很大影响。
Combining the results of modal experiment analysis on body - in - white and the results of finite element analysis , structural dynamics modification on the car front - body of a monocoque body has been made based on optimization algorithm 结合轿车白车身试验模态分析和有限元分析的结果,成功地对某承载式轿车车身的车头子系统结构进行了基于优化算法的结构动力学修改。
The existing assembly tolerance analysis and synthesis are mainly applied to the rigid assembly , and not suited to the deformable sheet metal assembly . it is necessary to find a new method that applied to the deformable sheet metal assembly . there is great meaning that we use the new method to make clear the variances sources and to improve the quality of the sheet metal assembly 现有装配偏差的分析与综合研究主要沿用了刚体装配误差理论,不适合柔性金属薄壁件,因此,寻求适用于具有柔性特点的薄板装配偏差研究方法,探明引起装配偏差的各类偏差源,对控制轿车车身等薄板装配偏差具有重要意义。
It exponds and summarizes the design method of car body car body internal layout , by the aid of basal design graphic tools , the software system of expert system based body interior layout was developed , design idea and method of the system were discussed , operation of the modules in the system were summarized , the way of the establishment of basal design modules used in car body interior was given . at last , combining with the mini - car project of the technical department of 999 auto group co . ltd and a new car project of a car research institute , this system was put to check its practicality and feasibility . the result was satisfactory 论文中阐述了专家系统和一般设计软件的不同,总结和分析了轿车车身内部基础布置设计的方法,借助于基础设计图形工具开发了基于专家系统的轿车车身内部布置设计的软件系统,论述了系统的设计思想和方法,总结了系统中的各模块运作形式,给出了轿车内部布置的基础设计模块的建立方法;最后结合三九汽车公司技术开发部的微型轿车项目以及某汽车研究所开发的新车型,就软件系统的实用性和可靠性进行了检验,结果令人满意。
