Optimization design method on volute structure of lift fans for air-cushion vehicle
英文摘要：The volute structure is the key connect component for lift fans and air-cushion vehicle, including the interaction of load transfer and vibration transfer. It is important to improve the structural design of volute to reduce the vibration intensity and strength risk. The working mode of air-cushion vehicle and its lift fans is studied to distinguish the structural damage risk on the volute structure. An optimization design method is presented subsequently. Moreover, a real volute structure is carried out for further study, whose vibration intensity is above the accepted level. A series of technology measures are designed to improve the structural property on load bearing and vibration transferring. the good effect is achieved compared to the origin volute structure, including the strength, deformation, vibration and fatigue. As a conclusion, this paper presents a good reference for the structural design on volute of lift fans for air-cushion vehicle.
