基于UG的平面连杆机构运动仿真和分析

所谓机构的运动分析,就是对机构的位移、速度、加速度进行分析。在已知原动件的运动规律的条件下,分析机构中其余构件上各点的位移、轨迹、速度和加速度,以及这些构件的角位移、角速度和角加速度。为此,介绍了如何利用UG软件来实现连杆机构运动仿真和分析的方法及步骤。以平面六杆机构为例,在UG/Motion模块中,用动画来表现机构的运动过程,用图表和电子表格来反映运动仿真的结果,得到精确机构运动数据,为机构的优化设计提供参考依据。

The motion simulation and snalysis of planar linkages based on UG

This article introduces the method and procedure how to realizes the motion simulation and analysis of linkages using the UG software. Takeing the planar six-bar mechanism for example,the rate process of mechanism can be displaied with the animation and the result of motion simulation can be reflected with the graphic and the electronicforms in UG/Motion module.The accurate data obtains from the result provides the reference for the mechanism optimized design.
