 摘要：在保证吊装安全的前提下，对静音发电机组的吊装结构进行轻量化改进设计。将2组吊装横梁、4个吊耳的吊装结构优化升级为1组吊装横梁、2个吊耳的吊装结构；通过理论计算选择最佳吊耳厚度，利用仿真软件Abaqus进行可靠性及偏移量建模仿真，对优化后的静音发电机组吊装结构进行起吊试验验证。试验结果表明，优化后吊装结构的强度及机组的平衡性满足起吊要求。优化后的吊装结构安全可靠，减轻了质量，降低了制造成本，提高了产品竞争力。

 Abstract： Considering the basic safety of hoisting, the lifting structure of the silent generator set is improved by lightweight design. The lifting structure of 2 groups lifting beams and 4 lifting lugs is optimized and upgraded to 1 group of lifting beams and 2 lifting lugs. The optimal lifting lug thickness is selected through theoretical calculation, and the reliability and offset are simulated by Abaqus. The lifting test is also carried out to verify the optimized lifting structure of silent generator set. The test results show that the strength of the optimized lifting structure and the balance of the unit meet the lifting requirements. The optimized hoisting structure is safe and reliable, which not only reduces the weight and manufacturing cost, but also helps to improve the product competitiveness.
