1. 研究目的与意义（文献综述）
with the rapid development of industrial technology and informationtechnology, the system equipment in various fields related to automobilemanufacturing is becoming more and more complex, and the degree of integrationand intelligence is also improving. with the development of complex equipment,the whole life cycle cost in design, development, test, operation, maintenanceand so on increases greatly. therefore, higher requirements are put forward forthe display form of data and the omni-directional display of the actualoperation of the organization.
with the rapid development of industrial technology, the development ofmodeling and simulation, which is widely used in automobile design andevaluation, has not slowed down. in the 1960s, modeling and simulationtechniques could only calculate specific physical phenomena with relativesimplicity. however, with the continuous improvement of computing power andalgorithm and the improvement of sensor technology, it has reached the pointthat it is not just in the design stage, but can conduct dynamic simulationthroughout the life cycle of the product.
driven by the advance of simulation technology and the actual demand ofcomplex mechanism, the research of real-time simulation technology hasgradually become a hot topic.
2. 研究的基本内容与方案
the basic content
(1) establishmodels of automobile machinery institutions. processing materials and textures ofit to achieve a high degree of similarity. asan example, the research will start from the door with hinged relation. andgradually try to simulate the power mechanism on the chassis, includinggearbox, universal joint, engine and other chassis components.
(2) simplify thepart model drawn to reduce the loading time of the geometric model and the timeto change on the simulation platform.
