The Research of Using Step Function to Simulate the Step-Movement of Forklift Machine in Mechanical Engineering Based on ADAMS

Article Preview

Abstract:

the movements of forklift mainly include the forward and backward of body,driving of boom cylinder to stick cylinder, flipping and lifting of stick cylinder to shovel,and the recovery of them after the completion of these actions.The paper puts forward using step function in ADAMS to simulate these movements. First, the solid modeling of a forklift established in ADAMS. And then, the step function was utilized to carry on emulation step by step. The concret form of step function is step(parameter,time1,position1,time2,position2),the parameter here is time.The component is in position1 at time1.The component is in position2 at time2.At the same time, the utilization of combined step functions ,which means multiply step functions are add to components , can realize various motions at different time.The step movement is achieved consequently
