摘要:针对某科考船冷却水泵组开展泵组隔振设计。通过上下层隔振器选型及中间筏体结构设计,使系统的各阶模态频率在一定程度上低于主要扰动频率,同时使筏体的主要振动模态远离扰动频率。仿真计算和实船测试结果验证了该泵组隔振设计达到相应设计要求。 |

Abstract:The vibration isolation design of the cooling water pump set of a scientific research vessel was carried out. To make the modal frequency of different orders lower than main disturbance frequency to some extend, and keep the main vibration mode far away from the disturbance frequency, the type selection of upper and lower vibration isolators and the structural design of middle raft were carried out. The simulating calculation and on board test results verified that this pump set vibration design could meet the design requirements. |
