【摘要】 在考虑温度对圆柱壳材料性能影响的基础上 ,采用伽辽金原理及Melnikov法研究了圆柱壳在热载荷及微扰外压作用下的分岔 ,并讨论分析了温度、长径比、厚径比对圆柱壳发生混沌运动区域的影响。更多还原

【Abstract】 WT5BZ]Based on the temperature effected cylindric shell material property,Galerkin principle and Melnikov method are used to study cylindric shell’s bifurcation characteristics which are affected by heat load and microdisturbing external compression.The influence of temperature,slender proportion and thickness_radius ratio on the region of chaotic motion are analysed,更多还原
