The Dynamic Analysis of high-speed cam with Considering Damping

摘要

With the applied development of Cam mechanism in modern civilization, the running speed of cam mechanisms is increasingly high, the inertial force of system follower raced up. Dynamic analysis and dynamic design must be considered when analyzing high-speed cam mechanism. This article takes combustion engine high-speed Valve cam for example, adopt cyclical motion rule when calculating, follower system would be equaled to Single freedom dynamic model and movement equation would be established. Meanwhile, establishing the movement equation. Use MATLAB to work dynamic response change curve to obtains the different period ratio to push the regulation sector principal oscillation response and ttop the secto sor hangover response far the influence, thus makes the explanation to the period ratio reasonable choice.
