针对目前高速滑撬系统滑块磨损严重、撬体振动剧烈、测试成本高、实验周期长的问题,提出一种适用于高速滑撬平台的电动悬浮和电磁推进系统。采用数值计算方法建立系统的仿真模型,对系统的悬浮和推进特性进行分析。仿真分析结果表明,系统最大浮重比是电磁吸力型(EMS)悬浮系统的11倍,推进系统需要撬体携带的重量仅占整个撬体质量的4.2%,具有很高的有效载荷。文中所提出的系统较传统的采用滑块支撑、火箭发动机作为动力的高速滑撬系统具有明显优势。
In order to solve the problem that the slider of the high-speed skid system is worn seriously, the prying body vibrates violently, the testing cost is high and the experimental period is long. At present, an electric levitation and electromagnetic propulsion system suitable for high-speed skidding platform is proposed. The numerical simulation method is used to establish the simulation model of the system, and the suspension and propulsion characteristics of the system are analyzed. The simulation results show that the maximum floating weight ratio of the system is 11 times that of the electromagnetic suspension system (EMS), and the propulsion system needs to carry only 4.2% of the total mass of the skid and has a very high payload. The system proposed in this article has obvious advantages over the traditional slider-supported and rocket-powered high-speed skid system.
