液粘柔性傳動過程及摩擦副熱變形優(yōu)化研究液粘柔性傳動過程及摩擦副熱變形優(yōu)化研究

摘要：

摩擦傳動在機械制造中廣泛應用，但隨著工作條件的變化，摩擦副會發(fā)生一系列物理、化學及機械變化，進而導致熱變形現(xiàn)象，影響摩擦傳動的性能。因此，研究摩擦副熱變形對摩擦傳動的影響，優(yōu)化液粘柔性傳動過程，具有重要的實際意義。

本文主要從液粘柔性傳動過程及摩擦副熱變形的角度出發(fā)，探討了摩擦傳動過程中的熱與動力學機制。首先，進行流體動力學和傳熱學的研究，并建立流體動力學和熱傳遞的數(shù)學模型。其次，通過實驗研究，得到了液粘柔性材料的力學參數(shù)，進而研究了液粘柔性傳動的動態(tài)特性。最后，針對液粘柔性材料的變形造成的摩擦副熱變形現(xiàn)象，利用數(shù)值模擬方法對其進行了優(yōu)化研究。通過對摩擦副材料及制造工藝的分析，得出了一系列優(yōu)化方案，以達到優(yōu)化傳動性能、提高制造標準、減少工藝難度和成本的目的。
