典型工况下垂直救援车载提升系统动力学分析

Dynamics analysis of vertical rescue vehicle-mounted hoisting system under typical working conditions

介绍了垂直救援车载提升系统组成及工作原理;采用UG建立了垂直救援车载提升系统三维模型,并将三维模型导入ADAMS中构建了系统动力学模型;利用动力学模型模拟了系统在救援舱空载下放、救援舱重载提升、救援舱紧急制动、钢丝绳过放等典型工况下钢丝绳受力及救援舱与地面的碰撞力情况,为系统设备选型和设计提供了理论依据。

Composition and working principle of vertical rescue vehicle-mounted hoisting system were introduced.A 3 Dmodel of the system was built by use of UG,which was introduced into ADAMS to build dynamics model of the system.Wire rope tension and collision force between rescue capsule and ground of the system under typical working conditions such as no-load lowering of rescue capsule,heavy-load lifting of rescue capsule,emergency braking of rescue capsule and over lowering of wire rope were simulated,which provide theoretical basis for selection and design of the system.
