    摘要:

    對履帶式車輛典型工況下的粘彈性懸架阻尼緩沖件的溫度場進行分析。不考慮材料參數(shù)的溫度相關性，對結構-溫度的耦合場進行單向解耦；將結構分析的結果作為溫度分析的條件，同時對溫度模型施加邊界條件。橡膠受載時為非線性大變形，使用有限元方法獲得數(shù)值解。求解得到典型工況下局部過熱點的位置和溫度值，得到溫度與影響因素的關系曲線，并進行公式擬合。分析結果可為粘彈性懸架阻尼緩沖件的結構優(yōu)化提供參數(shù)。

    Abstract:

    The temperature field of damping buffers for viscoelastic suspensions mounted on crawler vehicles was analyzed under typical working conditions. The temperature correlation of the material was ignored to decouple the structure-thermal coupling field. The analytical results of structure were used as the basic conditions for thermal analysis. Because of nonlinear and large deformation under load, the temperature field was calculated by finite element method (FEM). The positions of local hot spots and temperatures under typical loads were obtained by computation. The curves of temperature against factors and its fitting equation on engineering applications were also determined. The results provide reasonable parameters for damping buffers structure optimizing.
