摘要
水下航行体在出水过程中,横向受到由空泡回射和空泡溃灭带来的冲击压力,引起航行体横向的振动。本文建立了航行体的梁模型,考虑了出水过程中附加质量的变化,计算了出水过程中航行体横向振动频率、振型及响应。从计算结果可看出,在计算出水过程航行体横向响应时,应该考虑附加质量的变化。
The submarine vehicle suffers shock pressure in transverse direction by the re-entrance and collapse of the cavitation when moving out of water, resulting in the transverse vibration of the vehicle. A beam model of the vehicle is built by considering the change of the added mass in exiting-water process, and the transverse vibration frequency are calculated as well as the mode and transverse response. A related conclusion that the change of the added mass need to be considered in the calculation of the vehicle transverse response is drawn.
