中文摘要：
运动保真性-是凸轮机构设计的重要基础性和前提性条件。通过一个具体实例，引出运动失真现象、运动保真条件，分析得到失真仅可能出现于往程或返程的重要结论。提出影响运动保真性的两大类因素一离散参数和连续函数，以及较为深入系统地讨论了它们对运动保真性的影响规律。提出“失真”、“弱保真”和“强保真”的系统划分性概念，深化了对运动保真性的理解和认识，对摆动平底推杆盘形凸轮机构的分析设计具有重要参考价值和指导意义。
英文摘要：
Motion fidelity is the important basic quality and precondition of cam mechanism desion. Motion distortion and motion fidelity condition are proposed, and an important conclusion that motion distortion may appear only in actuating travel and return trave is put forward. Two factor-discrete parameter and continuous function-that can impact motion fidelity are proposed, and the effect of them to the motion fidelity are thoroughly and systematically discussed. The comcepts of ＂motion distortion＂ ,＂ critical motion fidelity＂, and ＂absolute motion fidelity＂ are proposed that can help to forge a deep understanding and awareness of motion fidelity, which has important value and implications in th design of plate cam mechanism with oscillating flat-faced follower.
