Abstract:
The sealing performance is directly related to the safety,reliability and mission success rate of aerospace equipment.The sealing performance of rubber seals and the optimized design of the compression force directly affect the performance and work efficiency of the equipment.Based on the hyperelastic Mooney-Rivlin model of nonlinear materials,the mechanical properties of rubber are simulated,and a finite element model of rubber seals is established.Through simulation analysis,the effects of different cross-section dimensions and compression amounts on the sealing performance are studied and compared,and key parameters such as the contact stress distribution,maximum contact stress,and compression force.The size of the fillet affects the final deformation and the contact state.By optimizing the geometric parameters,the compression force can be reduced while ensuring the sealing performance,providing a theoretical basis for the optimized design of rubber seals.
