Route Analysis of Trail Adjustable Wagon Based on Crank Rocker Mechanism

Abstract

The trajectory analysis of a transport wagon is a prerequisite for its rational path planning. In order to analyze the influence of crank and rocker lengths on the trajectory of a transport wagon in a four-bar spatial mechanism, two kinds of trajectories, single “8” and double “8” were simulated. The results show that changing the crank length will obviously change the trajectory shape, and changing the rocker length will mainly change the walking angle. This conclusion provides a basis for the route adjustment and planning of transport vehicles.
