那位大哥大姐帮忙我下面一段摘要翻译成英文
随着科学技术的发展,人们使用的机器设备功率增大、转速加快,在现代工程技术中振动这一普遍存在的现象日益受到人们的关注.为了提高舰船的战斗性和保证良好的性能,抗冲击成为军事家的重要课题.为了克服以上困难,人们经历了很多尝试,从单层隔振到双层隔振,再到浮筏隔振,使舰船的隔振与抗冲击性能越来越高.
本文利用有限元分析软件ANSYS,对舰船模型进行有限元建模,然后通过模态分析分别找出船体的固有频率和相应振型,避免在此产生共振.确定上层建筑整体的隔振与抗冲击方案,通过动力设备振动与船底冲击的模拟计算与响应分析,改变系统参数进行谐响应与冲击响应比较,对设计的上层建筑隔振与抗冲击方案进行分析、比较与对比.

Along with the development of science and technology,the use of machinery and equipment,power,speed accelerated In modern engineering technology vibration of the widespread phenomenon of increasing people's attention.In order to improve the combat ships and guarantee good performance,the impact strategist become an important issue.To overcome the above difficulties,a lot of people try to experience,from single to double isolation isolation and to the floating raft.enable ships with the isolation shock resistance is getting higher and higher.This paper uses finite element analysis software ANSYS,the ship model finite element modeling,Then modal analysis to identify the hull were the natural frequencies and mode shapes corresponding to avoid this resonate.Superstructure determine the overall impact of isolation and programs,through power equipment hull vibration and impact simulation and response analysis,change system parameters harmonic response compared with the impulse response of the superstructure isolator design and program impact analysis Compare and contrast.
