曲柄摇杆机构极位夹角的定义及图解设计新思路

The new definition of the angle at the extreme position of crank joystick structure and the new way of its illustration design

曲柄摇杆机构的急回特性与其极位夹角θ密切相关。通过对曲柄摇杆机构急回特性运动分析,提出更符合工程应用实际,具有通用性的新的极位夹角θ定义和反映行程速比系数k与极位夹角θ的关系式,并提出一种图解法设计的新思路。

The nasty return＇s character of crank joystick is related with its extreme position＇s angle. According the analysis to nasty return＇s character of crank joystick, putting forward a new definition of extreme position＇angle θ which more mathing the real of engineering application, and universal. And a related fomula between trip over the coefficient kand the extreme angle θ. And putting a new design way of illustration.
