插床导杆机构的设计造型与运动学仿真

The modeling and kinematics simulation of slotting's guide bar mechanism design

首先根据插床运动机构的设计要求,进行了插床导杆机构的设计与尺寸计算,然后运用Pro/E软件进行导杆机构的结构设计与造型,最后在ADMAS环境中建立该机构的虚拟样机模型,对机构的实际工况进行了仿真分析,得到了相关的工作特性曲线,并重点分析了插削长度、运动过程中的加速度和导杆摆角以及施加载荷情况等主要参数对机构运动的影响。对比仿真结果与设计要求,两者数据基本一致,验证了该设计的准确性。

According to the design requirements of the slotting machine,it analyzes the design and dimension calculation for the guide bar mechanism of this machine,establishes the structure design and three- dimensional modeling of each part for the guide rod mechanism based on Pro / E software,builds the virtual prototype model of the mechanism in ADAMS environment,realizes the mechanism simulation. It also illustrates a series curve of the performance characteristic,and discusses the main parameter related to the mechanism motion,such as slotting length,acceleration characteristic,guide rod swing angle,and load cases etc. Comparing with the design requirements,it shows the simulation results and verifies the accuracy of this design.
