摘要
针对间隔阻尼层合支重轮参数经验选取的不足,本文考虑了阻尼层合结构振动能耗散量对支重轮缓冲效果的影响,对其参数进行优化。建立了间隔阻尼层合支重轮振动能耗散模型;采用ANSYS参数化语言,以振动能耗散最大为目标,在常用工况下对其各层厚度、间隔角度进行优化,并在极端工况下验证了优化后支重轮的力学特性。结果表明,优化后支重轮的应力、应变在合理范围内,其振动能耗散量相对优化前提高了83%。本文的优化结果可为阻尼材料在支重轮中的应用提供参考。
According to the shortcoming of parameters experience selection,parameters of segmented damping composite bogie wheel were optimized considering the effect of vibration dissipation energy on buffer quality. A vibration energy dissipation model for bogie wheel was established. Based on the maximum of dissipation energy,optimization of the thickness of each layer and segmented angle were developed by ANSYS parametric language under the common work condition; and then the mechanical characteristics of the optimized bogie wheel were verified under extreme work condition. The results showed that the stress-strain of the optimized bogie wheel was within the reasonable scope and its dissipation energy was raised 83% compared with that of the bogie wheel before optimization. The optimization results can provide reference for the application of damping materials in bogie wheel.
