| 摘要: |
| 采用子结构导纳法建立了由燃料泵、主机、隔振圈以及舱段壳体组成的动力舱段耦合结构振动传递计算模型,计算了耦合结构的机械导纳,并通过试验验证了模型的有效性。以燃料泵受到的激励载荷作为输入参数,求解了舱段壳体目标点处的振动响应,以此开展了参数影响规律研究,结果表明:在300~1 500 Hz频率范围内,采用密度及杨氏模量较小的材料作为燃料泵选材能够有效降低舱段壳体的振动响应;摆盘箱结构参数对于舱段壳体振动响应的影响比气缸体结构参数更为显著,增大摆盘箱结构的厚度能够降低舱段壳体的振动响应。 |

| Abstract: |
| A parametric model of torpedo dynamic cabin, including auxiliary machinery, engine, ring isolator and cabin shell, was established based on substructure receptance method. The mechanical receptance of the coupling structure was calculated. The model was validated by mechanical receptance experiment. With the auxiliary machinery force as the input parameter, the vibration response of cabin shell was calculated. The influence of some major parameters was analyzed. Preliminary results show that choosing material of low Young modulus and low density as the material of auxiliary machinery can reduce the vibration response of cabin shell in the frequency band of 300~1 500 Hz; the parameters of swashplate box have a larger influence on the vibration of cabin shell than that of cylinder block and increasing the thickness of swashplate box can reduce the vibration response of cabin shell. |
