摘　　要：为满足凸轮机构运行精密度与稳定性的要求,建立凸轮从动件的结构优化评判体系。基于ANSYS软件构建船舶凸轮机构从动件模型,分析变形与未变形的模型边界和应力分布,以及位移与速度、加速度的关系。根据有限元分析结果,验证所选材料是否符合应力要求。结果表明,凸轮从动件在预期条件下的最大变形量为2.07×10^(-4) mm,变形量很小,在合理的范围内,应力分布从中心向外围逐渐减少,并且最大应力为13.4 MPa,远小于材料的极限值,可以满足凸轮机构使用要求。In order to meet the requirements of the precision and stability of cam mechanism operation,the structure optimization evaluation system of cam follower is established.The follower model of ship cam mechanism is built by ANSYS,and the boundary and stress distribution of the model with deformation and without deformation,as well as the relationship between displacement and velocity,acceleration are analyzed.According to the results of finite element analysis,we can verify whether the selected materials meet the stress requirements.The results show that the maximum deformation of the cam follower under the expected conditions is 2.07×10^(-4) mm,the deformation is very small within a reasonable range,the stress distribution is gradually reduced from the center to the outside,and the maximum stress is 13.4 MPa,which is far less than the limit value of the material,which can fully meet the requirements of the cam mechanism.
