摘要
目的研究薄型烟机包装跌落状态下的变形问题,并根据测试及仿真分析结果提出整改方向和具体措施。方法根据运输包装件跌落试验方法确定导致产品变形的跌落工况,基于Creo和Ansys Workbench软件进行产品包装件跌落仿真分析,得到产品的位移及应力分布。结果扫频测试共振频率与模态分析固有频率一致,证明了有限元模型建立的正确性;跌落过程中能量守恒证明了分析结果的正确性;最大位移分布于滤网、蜗壳、电机上,最大应力分布于产品外壳上;实验室测试与仿真分析得到的加速度随时间的变化趋势基本相同。结论分析产品跌落变形问题可采用实验室测试与有限元仿真分析相结合的方法,全面评价产品变形情况和应力集中现象。解决薄型烟机变形问题可通过增加衬垫、改进产品结构等方式实现。有限元模型的验证和分析过程中的能量守恒能够保证有限元分析结果的正确性。
The work aims to study the deformation of the thin-type kitchen ventilator package under drop condition, and put forward the rectification direction and specific measures according to the test and simulation analysis results. The drop condition causing product deformation was determined according to the drop test method of transport packages. Based on Creo and Ansys Workbench software, the drop simulation analysis of product packages was carried out, and the displacement and stress distribution of products were obtained. The consistency between resonance frequency measured by sweep frequency test and the natural frequency of modal analysis proved that the finite element model established was reasonable. The conservation of energy in the drop process proved that the analysis result was correct. The maximum displacement was distributed on filter, volute and motor. The maximum stress was distributed on the product shell. In addition, the trend of acceleration obtained from laboratory test varying with time was basically the same with that obtained by simulation analysis. In order to analyze the drop deformation of products, laboratory tests and finite element simulation analysis can be combined to comprehensively evaluate the deformation and stress concentration of products. The deformation problem of the thin-type kitchen ventilator can be solved by adding pads and improving the product structure, etc. The validation of the finite element model and the conservation of energy in the analysis process can ensure the correctness of the finite element analysis results.
