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。
For a rocket planetary gear reducer, the first use of ADMAS software to establish its rigid dynamics model and verified by the dynamic simulation of the model is correct, but also to obtain the key parts of the dynamic load in time and frequency domain curve; followed by the establishment of Decelerator box finite element model, the application of LMS Virtual.Lab software solved the forced vibration response of the box, and the use of acoustic boundary element method simulation analysis of the noise characteristics of the reducer. In order to further understand the dynamic characteristics of the high and low reducer laid the foundation for the reducer to optimize vibration and noise reduction to provide technical support.
