| 摘 要： | 采用弹簧单元模拟轮齿啮合刚度,杆单元模拟箱体间的联结螺栓,弹簧阻尼单元模拟滑动轴承和滚动轴承,建立由齿轮、传动轴、轴承和箱体等组成的GWC6066船用齿轮箱动态有限元分析模型及声学边界元模型;分析了齿轮箱在内部动态激励下的动态响应,预估了齿轮箱的振动烈度、结构噪声及空气噪声,并对齿轮箱进行实验模态分析及振动噪声测试,与仿真结果对比分析,二者吻合良好。

| Abstract: | The mesh stiffness of gear tooth is simulated by spring elements,the connected bolt between various housings are simplified as bar elements,and the sliding bearing and rolling bearing are simplified as spring dumping elements.Based on them,the gear-shaft-bearing-housing coupled finite element model and boundary element model of GWC6066 marine gearbox are established.Finally,the dynamic response under internal dynamic excitation is analyzed and the vibration severity,structural-borne noise and air-borne nois... |
