Analysis of Instantaneous Center of Zero Acceleration of Rigid Body in Planar Motion

Haibin Sun, Tingting Liu


When the angular velocity vector of rigid body in the plane motion unequal to zero, we can certainly find a point which instantaneous acceleration equal to zero at that particular instant. The point is named instantaneous center of zero acceleration. We proved the existence of the point and obtained the location of the point. We could solve mechanical problem quickly using instantaneous center of acceleration as base point.
