摘要
针对履带式车辆现用刚性支重轮减振降噪效果较差的现状,设计了两种不同减振方案支重轮—间隔和非间隔式阻尼支重轮。利用有限元分析技术,分别建立了两种阻尼支重轮实体模型,在考虑结构材料、几何、接触非线性的条件下,进行了阻尼支重轮力学性能(径向应力、应变、位移)的计算,结果表明,在给定的条件下,两种方案在工作环境中均可以在较短时间内消耗掉输入的振动能量,具有较好的减振性能,其中以间隔式效果更佳。这里的阻尼减振方案,对今后阻尼减振降噪技术在管(杆)状对称结构中的应用有一定的参考价值。
According to the status of the existing rigid bogie wheel＇s poor damping effect,two different damping schemes are designed：segmented and non-segmented damping bogie wheel,which are used in crawler vehicle.By using the finite element analysis technology,entity model of the damping bogie wheel was set up.When the material,geometric,contact nonlinearity were considered,the mechanical characteristics （Longitudinal stress,strain and displacement） of damping bogie wheel were calculated.The results showed that two kinds of design schemes in the working environment have the better vibration-reducing effect.They could consume vibration energy in a relatively short period of time.And the segmented damping bogie wheel has better damping property than the other.Damping scheme in this paper could give a certain reference for the damping technology application in the tube or shaft structure.
