The Virtual Assembly of 2K-H Planetaray Gear Transmission based on UG

论述实现2K-H行星齿轮传动虚拟装配的两种方法,基于UG关联约束的方法和基于尺寸驱动技术的方法,指出基于尺寸驱动技术的装配建模更易于程序实现。最后,基于UG装配建模环境,利用尺寸驱动技术通过UG/OpenAPI二次开发实现了2K-H行星齿轮传动虚拟装配,并给出部分代码。实践表明,所得装配模型可用于减速器的运动仿真研究。

Two kinds of method to implement virtual assembly of 2K-H planet gear transmission-are presented according to UG connection constraint method and dimension-driving. It is pointed out that assembly modeling based on dimension -driving is realized easily by program. In the end, using UG/Open API by making use of dimension-driving technique on the basis of UG/assembly modeling, virtual assembly of 2K-H planetaray gear transmission is implemented. Some code is given out. Practice demonstrators that this assembly modeling can be used for simulation of mechanism animation.
