Study on influence of coaxality deviation on interfacial pressure of shrink-fit cylinder

The paper established the mathematical model of two-layer shrink-fit cylinder with proper coaxality deviation based on the theory about elastic-plastic shrink-fit cylinder. An example was applied to show that the interfacial pressure value of the mathematical model was identical with the data of finite element analysis, which indicated the model conformed to actual condition and possessed some theoretical guidance for actual project. The application of the model indicated the coaxality deviation of shrink-fit cylinder should be controlled strictly since the interfacial pressure between inner cylinder and outer one decreased gradually around the circumference.
