高速凸轮机构重要的研究课题之一就是从动件运动规律的设计。 本文提出的“综合对称型运动规律”,在一定程度上兼收各种基本运动规律的优点,该运动规律的特性指标优于目前文献所给出的结果。该运动规律增加了设计参数,因而给设计运动规律带来了灵活性,可从特性指标坐标图上选择合适的设计参数,设计出合乎要求的运动规律。 One of the important research topics of high-speed cam mechanism is the design of follower motion. The “Symmetric symmetrical movement rule” proposed in this paper, to a certain extent, incorporates the advantages of various basic movement rules. The characteristic index of the movement rule is superior to the results given in the current literature. This law of motion increases the design parameters, thus giving flexibility to the laws of design movement. The appropriate design parameters can be selected from the characteristic index coordinates to design the desired motion law.
