摘　　要：目的 为保障大型工业机械装配、包装、起吊与转运的安全性,对其吊具系统进行结构强度分析与优化设计。方法 设计地脚承重试验,采用称重传感器获得接装机重量,确定吊具载荷。建立烟支接装机吊具有限元分析模型,研究偏载系数为1.5时准静态状态下吊具的应力应变分布规律。基于结构最大应力和许用安全因子,对吊具结构进行优化。结果 优化后底板最大应力为79.6 MPa,安全因子大于3。起吊构件的最大应力为47.6 MPa,安全因子大于5。撑杆部件结构优化后,撑杆最大应力为175 MPa,安全因子大于1.3。接装机起吊试验结果表明,设计的吊具可安全起吊和转运接装机,试验结果与模拟结果相符。结论 设计与优化的吊具结构满足强度要求,能安全起吊、包装和转运接装机。本文的研究为工业机械设备系统性包装运输的安全设计提供了重要理论依据。The work aims to analyze the structural strength of filter assembler spreader and optimize its design to ensure the safety of large industrial machinery in assembly, packaging, lifting and transfer. Foot weighing test was designed to obtain the weight of filter assembler by the weighing sensor and determine the load of the spreader. The finite element analysis model of the cigarette filter assembler spreader was established. Under the quasi-static state, the stress-strain distribution of the spreader was discussed with a partial load coefficient of 1.5. Then, the spreader structure was optimized based on the maximum structural stress and allowable safety factors. The maximum stress of the bottom plate was 79.6 MPa, and the safety factor was greater than 3. The maximum stress of the lifting member was 47.6 MPa,and the safety factor exceeded 5. Besides, the maximum stress of the optimized brace parts was 175 MPa, and the safety factor was greater than 1.3. Finally, the lifting test was carried out to the filter assembler spreader. According to the test results, the designed spreader could lift and transfer the filter assembler safely. The test results were consistent with the simulation results. The designed and optimized spreader structure meets the strength requirements and can lift, package and transfer the filter assembler safely. The research provides an important theoretical basis for the safety design of industrial machinery system in package and transfer.
