| 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.

| Abstract: | 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. |
