Free Modal Calculation of Cylinder Head of an Engine

As the demand for high speed and light weight of automobiles continues to increase, the requirements for power, volume and weight of the engine are also increasing. In the design and development of automobile engine cylinder head, the finite element analysis of its structural strength, stiffness and finite element model is used to analyze the static strength and finite element modal analysis of the cylinder head. The natural frequency and mode state of the cylinder head structure under the free mode and restrained mode are simulated and calculated, and the reliability of the structure is proved to be reliable. It provides a theoretical reference for subsequent casing design
