壳体振动 meaning in English
hull vibration
Examples
- Experimental study on vibration isolation of sandwich shell infused with er fluid
电流变液夹层壳体振动隔离的实验研究 - The noise of such structures root in the shell vibration that drove by the inner engine , when coupled with the liquid medium , the noise will affect the performance of the vessels badly
这些航行器的结构噪声来源于内部机械激励壳体振动，并带动周围流体介质振动产生声辐射，它严重影响了水下航行器的整体性能。 - If you add to this the effects of a sonar set mounted in the small nose of a torpedo rushing through the water at speeds up to 80 miles per hour with its consequence noise and vibration , plus hull borne vibrations from the power plant , it can be seen that only the most advanced electronic filtering gives any chance of success
如果再加鱼雷在水中以每个小时高达80海里的速度前进时所产生的噪声和震动对安装在小小雷顶声纳的作用，加之动力装置所产生的壳体振动，就不难看出，只有最先进的电子滤波才可能有成功的机会。 - Vibration response distributions of single ring stiffened cylindrical shell and multi - ring stiffened cylindrical shell are studied . the simulation results calculations of vibration level and radiated power level are gotten , about the single - ring stiffened cylindrical shell with average distribution force exciting along its one end
对单筋圆柱壳体在一端受均布力作用下的表面振级和声辐射功率级进行了仿真计算，分析了加筋处理对圆柱壳体振动和声辐射的影响。 - The submarine structure is simplified to single or double infinite cylindrical shell stiffened with rings , bulkheads and stringers , focusing on underwater sound radiation from the single shell . the shell motion is described by donnell ' s theory including excitation forces and reactions of rings , bulkheads , stringers and fluid , which leads to the fluid - structure coupling vibration equation . expressing displacements by velocities , applying modal expansion circumferentially and fourier transformation longitudinally result in the shell ' s modal equations of motion
壳体的运动方程采用较为简单的donnell理论描述，运动方程中包括了激励力、加筋结构(环肋、舱壁和纵骨)和流场对壳体的作用力，从而组成流场-结构的耦合振动方程，并进一步将方程中的位移用速度表示，然后沿轴线方向进行fourier变换，将速度和各项荷载沿圆周方向进行模态展开，得到了壳体振动的模态运动方程。
