Abstract

A half-tracked tractor equipped with an oscillating crawler system has better stability on uneven ground than wheel type tractors, which respond directly to a concavo-convex surface. However, the crawler tension fluctuates according to the variation in the perimeter of the crawler unit, since the hitch point of the oscillating frame is set separately from the drive axis of the drive sprocket. It is suggested that this fluctuation of the crawler tension would influence the driving performance. This study aims to evaluate the relationship between the crawler tension and the driving performance of the oscillating crawler unit using kinematics simulation. The ultimate objective is to achieve traveling control with fluctuation in the crawler tension. This paper introduces a rubber crawler model that is able to simulate the fluctuation in the crawler tension. In the driving simulation, the effect of the elastic parameters of the crawler and support spring on the driving performance of the oscillating crawler unit was examined. It was observed that the driving performance of the oscillating crawler unit is affected by the parameters of the rubber crawler and the support spring of the idle roller.

研究履带张力波动的简单橡胶履带模型

采用摆动履带系统的半履带拖拉机在凹凸路面上的稳定性优于直接响应凹凸路面的轮式拖拉机。然而，履带张力根据履带单元周长的变化而波动，因为振荡框架的悬挂点与驱动链轮的驱动轴分开设置。履带张力的波动会影响履带的行驶性能。本研究旨在利用运动学模拟的方法来评估履带张力与摆动履带单元驱动性能之间的关系。最终目标是在履带张力波动的情况下实现行走控制。本文介绍了一种能够模拟履带张力波动的橡胶履带模型。在驱动仿真中，考察了履带和支承弹簧的弹性参数对摆动履带单元驱动性能的影响。研究发现，橡胶履带参数和惰轮支撑弹簧对振荡履带单元的驱动性能有影响。
