平面四杆机构死点问题探讨及应用

Study on dead point of plane four-bar linkages mechanism and its application

主要以曲柄摇杆机构为例,分析了平面四杆机构死点实质、极限位置、形成死点条件等,为平面四杆机构解决死点问题、利用死点特性提供了理论依据。研究发现机构死点问题可以设法消除,而且存在着一定的应用和发展空间。

The dead point position of crank-rocker was studied by analyzing dead point＇s essence,limiting position and factors of forming dead point.So the purpose is providing theory evidence and using the dead point feature to solve the dead point problem.The results show that the dead point problem of mechanism can be removed and have a number of applications and development space.
