摘要
传统的图表分析型ＤＦＡ虽然对改进产品的可装配性有显著作用，但其可视化程度较差．为弥补这一不足，提出了一种装配仿真系统，可在产品设计阶段生动直观地进行预装配，验证和改进产品的装配工艺．着重介绍了系统的２个关键技术：装／拆运动的１１元组表示及变换可实现装配元件任意运动的模拟，装配路径有效性检查的递进算法能较大程度地提高运算效率．该系统已在商用ＣＡＤ软件Ｐｒｏ／Ｅｎｇｉｎｅｒ的基础上用Ｃ和Ｐｒｏ／Ｄｅｖｅｌｏｐ开发成功，并在工程实际中用作ＤＦＡ的可视化工具．
Conventionally, DFA methods are table chart
based and are lacking in visualization, even though application of them can improve product
assemblability significantly. As a complementary approach to DFA, an assembly simulation
system is presented in this paper, with which a product at design stage can be pre assembled
dramatically, meanwhile its assembly process plans can be verified and improved. Two of the
key technologies for the system are emphasized: the first is an 11 tuple representation for
assembly/disassembly movement and its transforms which enable arbitrary element
movements in an assembly to be simulated, the second is a gradual algorithm which provides
a fast and efficient way of validity check for assembly trajectories. Now, based on the
commercial CAD software Pro/Engineer, the system is implemented with C and Pro/Develop,
and has been used as a visualization tool of DFA in an engineering project.
