基于UG的内燃机活塞机构虚拟装配和运动仿真

Virtual assembly and movement emulation for piston mechanism of internal combustion engines based on UG

为改变二维设计的不足和适应现代化的需要,借助UG强大的建模和装配技术,分析了内燃机活塞机构中各构件的三维建模过程及构件之间的虚拟装配过程;通过UG的仿真技术,对内燃机活塞机构设计过程中的连杆创建、运动创建、驱动定义等环节进行了分析。实践证明,利用UG进行虚拟装配和运动仿真,可以缩短产品的研发周期,提高生产效率。

In order to conquer the shortage of two-dimensional design and adapt to the needs of modernization, combining with the strong function of modeling and assembly technology of modern CAD software UG, the authors analyzed the detailed modeling process of piston mechanism in internal combustion engine and introduced the virtual assembly process of all components. Based on the simulation function of UG, it was analyzed for the movements of all components in piston mechanism. Finally, the CAD software UG shows its strong advantage of mechanical design with flexibility and low cost.
