Abstract

Vehicle terrain mobility characteristics, provided by the powertrain and running gear, are realized in dynamic interactions between the wheels and terrain. Approaches to modeling and simulation of vehicle-terrain interaction and mobility characteristics as well as engineering approaches to design powertrain sub-systems together pre-determine a vehicle’s technical success or failure before it touches the ground. This article develops a vehicle mobility design technique, applicable to both manned and unmanned platforms, concerned with powertrain power conversion and realization in tire-terrain interactions. The modeling component is based on multi-drive-wheel vehicle longitudinal dynamics combined with terramechanics and powertrain characteristics. The approach advances the conventional dynamic factor by introducing the conjoint effect of the engine, transmission, and driveline system on vehicle traction and acceleration performance in terrain conditions where circumferential wheel forces and tire slippages may differ from each other. The vehicle design component of the proposed technique introduces drivetrain, driveline, and powertrain design factors that assess the influence of the drivetrain and driveline systems on traction, acceleration performance, power conversion, and realization at the wheels. The vehicle-design-for-mobility technique is completed by examining indices of mobility margins and performance. An analysis of several 8x8 armored personal carriers and 4x4 off-road vehicles illustrates the proposed technique.

地形机动车辆设计:一种动力总成功率转换建模技术及其实现
车辆的地形机动特性是在车轮与地形的动态相互作用中实现的,由动力总成和行走装置提供动力。车辆与地形相互作用和机动性特性的建模和仿真方法,以及设计动力总成子系统的工程方法,共同决定了车辆在接触地面之前的技术成功或失败。本文发展了一种适用于有人驾驶和无人驾驶平台的车辆机动设计技术,涉及轮胎-地形相互作用下动力系统功率的转换与实现。建模组件基于多驱动轮车辆纵向动力学,结合地形力学和动力系统特性。该方法通过引入发动机、变速器和传动系统对车辆在不同地形条件下的牵引和加速性能的共同影响,改进了传统的动力因素。该技术的车辆设计部分介绍了动力传动系统、传动系统和动力传动系统设计因素,这些因素评估了动力传动系统和传动系统对牵引力、加速性能、动力转换和车轮实现的影响。机动车辆设计技术是通过考察机动余量和性能指标来完成的。对几辆8 × 8装甲个人运输车和4 × 4越野车的分析说明了所提出的技术。
