摘要

采用三角形变化历程对设备冲击输入谱进行简化

考虑设备抗冲隔离系统的影响

对舰船动力机组在时域上进行数值模拟。分别对舰船动力机组整体和主汽轮机组以及主减速齿轮装置进行冲击加载。通过对不同加载方式的对比分析发现

整体加载时主汽轮机组的动态响应要比主减速齿轮装置剧烈;无论是主汽轮机组还是主减速齿轮装置单独加载时

结构的动态响应都要比动力机组整体加载时剧烈;动力机组的抗冲隔离系统是一个整体

在整体加载工况下其抗冲隔离效果更为明显

可以更好地起到抗冲减振作用。

Abstract

Triangle transformation course is employed to simplify the shock input spectrum of equipments and the shock resistance shielding system is simulated with the finite element method.In time domain

impulse load is loaded on the marine power unites integrally first

then loaded on turboset and the gearcase respectively.Through the comparison of different loading methods

it is found out that the dynamic response of the turboset is more serious than the gearcase when loaded integrally;both the dynamic response of the turboset and that of the gearcase when loaded respectively is more serious than that of the power unite when it is loaded integrally;the shock resistance shielding system of power unite is an ensemble

the effect of its shock resistance and isolation is more obvious when it is loaded integrally

and that can resist shock and vibration more effectively.
