摘要

针对某火箭炮高低行星减速器,首先应用ADMAS软件建立其刚性动力学模型并通过动力学仿真验证了模型的正确性,又进一步得出了关键部位动载荷的时域与频域曲线;其次建立了减速器箱体的有限元模型,应用LMS Virtual.Lab软件求解出了箱体的强迫振动响应特性,并利用声学边界元方法仿真分析了减速器的噪声特性。为进一步了解该高低减速器的动态特性奠定了基础,也为该减速器开展减振降噪优化设计提供技术支撑。

Abstract

For a rocket artillery elevating mechanism planetary reducer,firstly the rigid dynamics model is built by using the software ADAMS and the rightness of the model is verified through dynamics simulation,then,the dynamic load in time- domain and frequency- domain for the key parts of the reducer are obtained.Secondly,the finite element modal of the reducer box is established and the forced vibration response of the reducer is calculated with the software LMS Virtual. Lab and its vibration noise characteristics is simulated by using the acoustic boundary element method. A foundation for further understand the dynamic performance of the rocket artillery elevating mechanism reducer is provided,and the technical support for the optimal design of vibration and noise reduction of this sort of reducer is also provided.
