| 中文摘要: |
| 目的 寻找修枝机整机跌落时的易破损部件，以便针对易损部件设计更合理的结构和缓冲防护包装。方法 基于Hypermesh和LS-DYNA软件对修枝机水平跌落、竖直侧向跌落这2种极限工况进行仿真分析。结果 在2种工况下，旋转管均会发生应力集中，出现破损，影响修枝机使用寿命。结论 在今后的产品设计中，要重点对旋转管的结构进行优化设计；在运输过程中，要着重针对旋转管部件设计合理的运输包装防护结构。 |
| 英文摘要: |
| The work aims to find out the quick-wear parts of complete pruning machine at the time of falling off, so as to design a more reasonable structure and buffer protective packaging. Simulation analysis was carried out for two kinds of drop conditions of the pruning machine based on Hypermesh and LS-DYNA, namely horizontal falling and vertical lateral falling. In these two cases, the rotary tube would be subject to stress concentration and damaged. This would affect the service life of the pruning machine. In the following product design, the emphasis should be placed on the optimized design of the rotary tube’s structure. In the process of transportation, the stress should focus on the design of a reasonable transport packaging protection structure for the rotary tube components. |
