Parameter Study of a Step-Climbing Machine for Heavy Load Carriers

摘要

This paper presents the development of a new step-climbing mechanism for heavy load carriers. According to the method of measurement used, the results of experiments are given as the values of resistance and required driving force against a 10 mm step. The basic design of the proposed mechanism is illustrated, and a prototype is manufactured. Measuring impact acceleration using the prototype, we verify the accuracy of the mechanism CAE analysis. In addition, using the mechanism CAE analysis, we reveal the relation-ship between the angle, link length, and performance. Several experiments demonstrate that this prototype is able to drive over a 10 mm step, proving the effectiveness of the proposed mechanism.
