该文介绍了推拉式气垫平台的结构 ,定义了该种非常规地面运载车辆的运动方式 ,并分析了它的运动学。整个气垫平台由结构相同的 2个平台串联组成 ,由液压机构相联接 ,前、后平台可互为固定的基础平台和运动平台 ,用液压机构推动或拉动。 This paper introduces the structure of the push-pull air cushion platform, defines the movement mode of the unconventional ground-carrying vehicle and analyzes its kinematics. The entire air cushion platform is composed of two platforms of the same structure connected in series, and is connected by a hydraulic mechanism. The front and rear platforms can be mutually fixed base platforms and motion platforms, and can be pushed or pulled by the hydraulic mechanism.
