摘　　要：为研究海港岸桥主起升环节的液压盘式制动器在工作过程中受到制动力的应力应变状况以及力学性能,首先建立盘式制动器的三维模型,然后根据有限元原理,运用有限元分析软件ANSYS Workbench对其进行静应力分析,得到制动器主要零部件应力、变形情况和应力、变形云图以及其主要部件的应力大小,并对出现应力集中的地方进行优化改进。同时提出增大制动臂底处连轴半径的方法,将原来的连轴半径由30 mm增大到35 mm并对其进行同条件下分析验证,为此盘式制动器的优化设计及动力学分析提供理论基础。通过模态分析,得出其前6阶固有频率和振型,通过计算分析得到结果验证该制动器在制动过程中不会发生共振,结构安全可靠,能满足实际工作要求。In order to study the stress,strain and mechanical properties of the hydraulic disc brake of the main hoisting link of the quayside crane,the three-dimensional model of the disc brake is established first;then,according to the finite element principle,the static stress of the disc brake is analyzed using the finite element analysis software ANSYS Workbench,and the stress,deformation cloud diagram and the stress of the main parts of the brake are obtained;this paper also optimizes and improves the place where the stress concentration occurs.At the same time,the method of increasing the connecting shaft radius at the bottom of the brake arm is proposed,and the original connecting shaft radius is increased to 30 mm to 35 mm;it is analyzed and verified in the same conditions,which provides a theoretical basis for the optimal design and dynamic analysis of the disc brake.Through modal analysis,the first six natural frequencies and vibration modes are obtained.The results show that the brake will not resonate in the braking process,and the structure is safe and reliable,thereby can meet the requirements of practical work.
