Inertial Vibration Characteristics of Track Chassis Caused by Reciprocating Motion of Crank Slider

Shock and Vibration, 2019
The crank slider of self-propelled 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.
