摘　　要：针对船用齿轮箱振动监测位置设置不精准的问题,文章基于Solidworks+HyperMesh+ABAQUS的组合平台,建立了齿轮箱三维实体模型及有限元模型,开展约束模态分析和冲击响应分析,研究了船用齿轮箱箱体、传动齿轮系的振动模态和冲击响应特性,掌握了不同激励频率下的振动响应敏感部位,为振动监测位置确定提供了依据。Aiming at the problem of inaccurate positioning for vibration monitoring of marine gear boxes,this paper builds a three-dimensional solid model and finite element model of the gear box by using the combination platform of Solidworks+HyperMesh+ABAQUS.The paper conducts the constrained modal analysis and impact response analysis.In addition,this paper studies the vibration modes and impact response characteristics of marine gear boxes and gear trains and grasps the sensitive parts of vibration response under different excitation frequencies,which provides a reference for determining the position of vibration monitoring.
