齿轮-五杆机构精确轨迹的综合

Accurate Path Synthesis for Geared Five-bar Mechanism

本文用CAD的几何约束和尺寸驱动技术,在多个复合精确轨迹情况下构造一个基本五杆模拟机构,再根据轨迹综合的原则,由基本五杆模拟机构创造出精确轨迹综合模拟机构。计算机模拟结果表明,该方法具有简洁直观、求解精确和重复性好的特点。

In the case of CAD geometric approach,for more than ten prescribed positions,first using the geometric constraints and dimension driving techniques,a primary simulation mechanism is created.After that,based on the task of path generation for the path synthesis,the simulation mechanisms of accurate path generator with Geared five-bar mechanism are developed from the primary simulation mechanism.The results of computer simulation show that the mechanism simulation approach is not only fairly quick and straightforward, but also has the advantages of accuracy and repeatability.
