摘要

心形曲柄是能够生成心形线的行星机构，使用心形曲柄替代导杆机构的驱动曲柄，相当于导杆机构具有一个变化的长度和速度、沿着心形线运动的曲柄，从而改变了导杆的运动特性。提出了心形曲柄导杆间歇运动机构，给出了运动分析、导杆极限位置、导杆摆角等计算方法，研究了按照导杆摆角设计近似间歇运动机构的设计方法，计算了导杆的最小长度，讨论了中心距对机构运动性能的影响。采用最小二乘法进行了机构参数逼近。

Abstract

The cardioid crank is a planet mechanism which is able to generate cardioid curve， with cardioid crank as the driven crank of the guide-bar mechanism is equal to the mechanism which has a crank of the varying length and varying speed and moving along the cardioid， which changed the kinematic characteristics of the guide-bar. A cardioid crank guide bar dwell motion mechanism is presented. The motion analysis and the calculation method of the limit position and oscillate angle of guide-bar are presented. The design method of approximate dwell motion mechanism is studied according to the guide-bar oscillate angle， the minimum length of guide bar is calculated， and the influence of center distance on the motion performance of the mechanism is discussed. The least square method is used to approximate the mechanism parameters.
