六足靴式气垫车的结构参数优化
首发时间:2013-09-30
摘要:软地面恶劣复杂环境下车辆的通过性一直是非路面车辆动力学及其控制领域的研究热点及难点。课题组在前期对半履带气垫车研究的基础上,提出一种以六个气垫靴作为行走机构的新型软地面概念车。该车通过驱动机构实现其纵向运动,而足的垂向运动则通过充放气实现。在本文中,先简单介绍了这种新型车辆的结构和工作原理,然后针对其结构和工作原理,分析确定了其所应当具备的约束条件。使用约束条件,建立标准化的数学表达式,利用matlab软件进行多约束优化设计,最终确定靴式气垫车的各项结构参数。

Parameter Optimization of the Six-Air-Cushion Boots Walking Concept Vehicle
Abstract:It has been a difficult but hot subject to improve the vehicle trafficability in some complex soft-terrain environments in the research area for off-road vehicle dynamics and control. Based on previous study for a semi-tracked air-cushion vehicle, a novel soft-terrain concept vehicle with a walking mechanism by using six air-cushion boots is proposed. The vehicle motion is realized by a driving-gears while the boots vertical motion is realized by air charging or discharging. In this paper, the structure and working principle of the vehicle are described firstly. Then the constraint conditions are proposed according to the structure and working mechanism of the new walking concept vehicle. With the constraint conditions, the mathematical equations are established and the multiple-constraint condition optimization is conducted in matlab in order to determine the structure parameters of the six-air-cushion boots walking concept vehicle.
Keywords: Soft-terrain vehicle Air-cushion boot Structure design Multiple-constraint condition design
