泡沫铝填充结构大型齿轮优化设计及其性能分析
Optimal design and properties analysis of large gear filled of foam aluminum
摘要
Abstract
In order to explore the new way to reduce weight,vibration and noise of large gear,this paper studies on optimal design and its properties of gear with aluminum foam by taking a large gear in mineral decelerator for an example.The first type,the gear with aluminum foam is designed by original gear.The second type,the gear is optimal designed by takdng torsion stiffness as constraint condition,taking maximum mass aluminum foam filled as object function.The third type,the modals of the three types of gear are analyzed by ANSYS,and their reduction noise is studied by test.It is shown that optimal designed and original gears filled aluminum foam are superior to original gear in dynamic properties and noise reduction.The first two types of gears are greater than original gear in the natural frequencies of the first 5 modes,the maximum increase is 16.1 and 1.9 percent respectively.In the same rotation speed,the first two types of gears are less than original gear in the amplitude of the first 5 modes,the maximum reduction is 10.0 and 5.4 percent respectively.The first two types of gears are lighter 10.92 and 15.93 percent than original gear,respectively.So gear filled aluminum foam is effective in improving light natural,vibration and noise reduction of large gear.关键词
