摘要
研究了3D-Kagome点阵夹芯板在高斯白噪声激励下横向非线性振动的响应统计特性。分别考察了3DKagome点阵夹芯板在高斯白噪声激励、面内谐和与高斯白噪声激励综合作用,2种不同工况下的横向响应统计特性,应用矩函数微分方程法推导了系统的二阶瞬态矩,利用高斯截断方案,求出二阶稳态矩,并讨论了系统参数对二阶稳态矩的影响,利用Monte Carlo数值仿真验证了本文近似方法的正确性。
Nonlinear response statistics of truss core sandwich plate subjected to the transverse excitations by Gaussian white noise in this paper. The response statistics of the transverse excitations,the transverse and the in-plane excitations are investigated respectivly. The method of the moment differential equations is applied to determinete second order transient moment. The second order steadystate moment are solved by the method of Gaussian truncation. The effects of the system parameters are examined by the Monte Carlo numerical simulations. The analytical results are verified by the numerical simulations.
