研究了线性强化材料索网结构的非线性振动。在考虑温度变化的基础上,研究了线性强化材料索网结构存在几何非线性变形的振动问题,利用Galerkin原理及改进的L-P法求出了线性强化材料索网结构非线性振动的近似解,讨论分析了温度、线性强化、振幅等因素对线性强化材料索网结构非线性振动固有频率的影响。

The influence of temperature on the nonlinear vibration of suspension network structure with linear hardening material was studied. The nonlinear vibration governing equation on account of geometric deformation was presented in consideration of temperature changing. The approximate solution of nonlinear vibration of suspension network structure with linear hardening material was given by use of Galerkin principle and Improved L-P method. The factors that affect the nonlinear vibration, such as, the degree of temperature changing, linear hardening as well as vibration amplitude were discussed.
