紧固件自动拆装过程仿真的设计方法研究

介绍了一种在AUTOCAD环境下,用参数化造型法,实现紧固件拆装过程自动仿真的设计方法.该方法把维修工具及紧固件的设计、工具维修性力学分析,以及维修过程的图形仿真合成在一起.工具及紧固件可以在给定点自动实现三维造型,并可连续进行过程仿真;当施加在紧固件上的外力超过其规定的受力范围时,将以图形方式自动显示,帮助操作者对维修操作过程进行判断.

Study of Design Method of Automatic Fastener Disassembling and Assembling Process Simulation

In this paper presents a design method of the automatic fastener disassembling and assembling simulation (AFDAS) under the environment of AutoCAD by using parametric modeling. This method integrates the tool and fastener design, the tool maintenance mechanics analyses and the maintenance graphics simulation into unity. 3-D models of tool and fastener can be developed at given point automatically and simulated continually. When the force applied on the fastener exceeds criteria for a particular fastener, a graphic expression is automatically displayed to help the operator to judge maintenance operation.
