摘　　要：在船舶艉轴的机械密封中,不同材料的配合将产生不同数值的磨损和变形量。基于ANSYS有限元软件,建立橡胶-硬质合金密封的二维热-力耦合模型,分析力与温度场、力与变形之间关系。结果表明,静环橡胶的温度最高点和磨损严重区域发生在二维耦合模型中接触端面的上端面;动环和静环由最初的全端面接触变为部分接触,间隙呈锥度形状;在二维耦合模型中,随着端面比压的增大,下端面变形量增加的梯度明显大于上端面变形量增加的梯度。s In the mechanical seal of stem shaft, different wear and deformation are produced with differentpaired material .Based on ANSYS software, the heat-pressure coupling model is established with the collocationof rubber-hard alloy of mechanical seal, which analyzes the relationship between pressure and temperature,pressure and deformation. The research demonstrates that the highest temperature of the static ring rubber andserious wear area is occurred on the upper of contact face in the two-dimensional coupling model. The dynamicring and the static ring from the initial full face contact transformation as the part of face contact and the gap istaper shape. In the two-dimensional coupling model, with the face specific pressure is increasing, the increasedgradient of the lower contact face is obviously greater than that of the upper contact face.
