汽车的设计、开发和使用离不开力学．简述汽车的发展历史、主要组成及其性能．介绍汽车工程中的几个关键力学问题，包括汽车轮胎力学、行驶稳定性分析、驱动与阻力、振动与噪声、碰撞力学与车身耐撞性、撞击损伤生物力学、行人保护力学等．展望了汽车工程中需要关注的力学问题．%Mechanics plays a key role in automotive design, development and utilization. The requirements of safety, energy efficiency, and environment protection for modern vehicles involve all disciplines of mechanics. This paper briefly introduces the history of vehicles development and its basic structure and performances. The state of the art of the vehicle mechanics is described with emphasis on the key problems in tire mechanics, vehicle directional stability, crashworthiness, and noise and vibration. The vehicles mechanics problems in the future are summarized.
