| 目的 解决操控台在按照振动试验考核过程中出现的内部结构散架、表面磨损等问题，通过振动试验考核，满足恶劣颠簸路段运输要求。方法 对操控台进行力学仿真，对操控台结构最大等效应力处进行优化设计，提出一种加固木箱填充聚氨酯发泡材料的包装方法，采用有限元仿真计算和剩余强度系数公式评估强度安全，并通过随机振动试验进行验证。结果 优化结构及改进包装后的操控台剩余强度系数大于1，随机振动试验后台体及包装箱未出现损坏现象。结论 操控台结构优化方式和新型包装方法具有合理性，满足振动试验考核和恶劣颠簸路段运输要求。 |
| 英文摘要: |
| The work aims to solve the problems of scattered internal structure and surface wear of the console in vibration test and assessment, and meet the requirements of vibration test and assessment of transportation in harsh and bumpy sections. The mechanical simulation of the console was carried out, the maximum equivalent stress of the console structure was optimized, and a packaging method of reinforced wooden box filled with polyurethane foam material was proposed. The strength safety was evaluated by finite element simulation calculation and residual strength coefficient formula, and verified by random vibration test. The results showed that the residual strength coefficient of the console after optimizing the structure and improving the packaging was greater than 1, and the console body and packaging box were not damaged after the random vibration test. Therefore, the structure optimization mode and new packaging method of the console are reasonable, which can meet the requirements of vibration test and transportation in harsh and bumpy sections. |
