| 摘 要： | 本文介绍了挖掘机用柴油机前端轮系设计研究与优化的过程和成果,详细介绍了柴油机前端轮系异响的原因分析、设计优化措施及结果。首先,确定风扇皮带轮包角过小和风扇功率消耗过大是导致轮系异响的主要原因。然后,制定设计优化措施,通过增加惰轮来改善风扇皮带轮包角,通过降低挖掘机匹配的风扇功率消耗,使皮带滑移率等技术参数满足设计标准。最后,通过仿真计算和试验验证,将研究成果和设计优化措施转化为产品,解决柴油机前端轮系异响,使挖掘机的整体噪声品质得到明显改善。

| Abstract: | This thesis introduces the optimization process and achievement of engine FEAD system for the excavator.Fist,confirm the main reason of FEAD system sound contains the fan pulley warp too low and the fan power too high.Second,make actions to solve the problem by adding a idle pulley and matching a low power fan.Last,transfer the research to production after simulation and test,which solve the FEAD system sound and improve the sound quality of excavator. |
