目的 对航天器铁路运输包装箱构型和加固方案进行设计并优化,满足航天器铁路运输要求。方法 按照铁路超限超重货物运输规则和装载加固规则,对铁路运输包装箱构型和加固方案进行设计,采用ANSYS Workbench进行仿真分析,优化牵拉加固方案。通过现场铁路实装运输试验,验证包装箱构型设计和牵拉加固方案的可行性和合理性。结果 铁路运输包装箱长度方向前后端面均需设置不少于6处承载能力不小于30 kN的牵拉点,采用8×19类直径为12 mm的钢丝绳,按照重心上方和重心下方同时牵拉加固的方案,可以满足铁路运输包装箱运输要求。结论 按照铁路机车车辆限界基本轮廓进行箱体构型,合理设计牵拉加固点和牵拉绳牵拉方向,可以满足航天器铁路运输包装箱加固运输要求。
Abstract
The work aims to design and optimize the configuration and reinforcement scheme of spacecraft railway transport packaging containers. According to the transportation rules of oversized and overweight goods by railway and the configuration and reinforcement rules, the packaging container configuration and reinforcement schemes for railway transport were designed. ANSYS Workbench was used for simulation analysis to optimize the traction reinforcement scheme. Through on-site railway transport tests, the feasibility and rationality of the packaging container configuration design and traction reinforcement scheme were verified. Both front and rear end faces of the packaging container in the moving direction shall be provided with no less than 6 traction points, each with a load-bearing capacity of no less than 30 kN. Using 8×19 type steel wire ropes with a diameter of 12 mm for pulling according to the scheme of traction and reinforcement simultaneously above and below the center of gravity could meet the transportation requirements of railway transport packaging containers. According to the basic outline of railway rolling stock clearance for container configuration design, reasonably designing the traction reinforcement points and the traction direction of the traction rope can meet the reinforcement transportation requirements for spacecraft railway transport packaging containers.
