| 目的 为了不断提高缓冲结构的综合防护性能，设计一种刚性和柔性模块组合化的一体式托架缓冲防护结构。方法 设计缓冲防护总体结构，分析总体结构的综合性功能，计算理论柔性模块缓冲性能，采用Ansys有限元静态模块分析贮存状态的托架强度，采用动态模块分析跌落状态的产品加速度冲击过载、产品位移量和托架强度。结果 缓冲防护结构强度小于材料抗拉强度，产品在跌落过程中受到的加速度冲击过载满足设计要求。结论 缓冲防护结构设计合理可行，综合防护性能更优，为缓冲防护领域结构设计和分析提供了设计和数据参考。 |

| The work aims to design an integrated bracket buffer protection structure composed of rigid and flexible modules to improve the comprehensive protection performance of buffer structure. The overall structure of buffer protection was designed. The comprehensive function of the overall structure was analyzed. The buffer performance of flexible modules was calculated theoretically. Ansys Finite element static module was used to analyze the strength of the bracket in storage. Dynamic module was used to analyze the product acceleration impact overload and displacement and the strength of the bracket in drop state. The strength of buffer protection structure was less than the tensile strength of material and the accelerated impact overload of the product during falling met the design requirements. The design of buffer protection structure is reasonable and feasible, so that the comprehensive protection performance is more excellent, providing design and data reference for structural design and analysis in the field of buffer protection. |
