基于的ProE直摆凸轮机构运动仿真

摘要

本课题所研究的直、摆组合凸轮机构是一种新型的机构类型，该机构通过直动从动件凸轮机构与摆动从动件凸轮机构组成联动凸轮机构，能够将主动件的转动转化为从动件上某点沿预期的曲线轨迹并以预期的运动规律运动。

在对直、摆组合凸轮机构理论分析的基础上，我们对直、摆组合凸轮机构进行了Pro/e 运动仿真，精确求解出了各凸轮的理论廓线、实际廓线及各构件结构尺寸等。丰富了机械原理学科的设计理论及内容，适应了在机构设计方面许多学者致力于寻求凸轮机构的精确解和使凸轮曲线多样化及从动件轨迹多样化的要求。

最后，选择预期圆线轨迹为例，利用计算机辅助设计(Pro/ENGINEER)对该机构进行零、部件及总体造型分析设计，并利用Pro/ENGINEER对该直、摆组合凸轮机构进行了运动仿真，以验证理论的正确性和可行性。

因此，对直、摆组合凸轮机构进行深入地研究有着较大的理论和现实意义，有广阔的应用前景。

Abstract

The Z.B Combinatory Cam Mechanism is a kind of new-type mechanism, it can come into a kind of combinatory-movement mechanism which joints translation driven member cam and swing follower cam .It can translate the revolution of the driving body into a point of the driven body which has the ability to move around the anticipation curvilinear path and move based on the anticipation movement rule.

Based on the theory in analyzing Z.B Combinatory Cam Mechanism，we simulate the mechanism in applying VB，solving the profile of theory,reality,cutter of cams,and the subject and dimension of all components exactly.Enriching the design-theory and content of the subject about mechanical principal .Adapting the request of many scholars in component design for searching the exact solution about cam-entity and making the cam-curve various and follower-profile various.

Lastly, taking the four-leaf rose curve for example, applying the Pro/ENGINEER to design the curve, entity and motive emulate for verifying the truth and feasibility of the theory.

Nowadays, researching the Z.B Combinatory Cam Mechanism, having the significance in theory and reality .The prospect is extensive.
