Inertial Vibration Characteristics of Track Chassis Caused by Reciprocating Motion of Crank Slider
The crank slider of selfâpropelled baling machinery is used for straw compression on the crawler chassis structure. During the reciprocating motion of the crank slider, the inertia of the piston will cause a greater shock to baling machinery. In this paper, the inertia of the crank slider piston was analyzed on crawler chassis.
