推导凸轮机构压力角表达式的通用有效新方法

A NEW,GENERAL AND EFFECTIVE METHOD FOR DERIVING THE PRESSURE ANGLE’S EXPRESSIONS OF CAM MECHANISMS

以虚位移原理为理论基础和出发点，提出了一种简单通用、行之有效的推导凸轮机构压力角表达式的新方法，它对于平面与空间凸轮机构同样适用．

Based on the virtual work principle,this paper puts forward a simple,geneml and effec-tive method for deriving the pressure angle expressiom,for cam mechanisms,This new method is suita-ble for planar and spatial cam mechanisms as well.
