研究了弹性地基各向同性简支梁非线性分析中轴向位移逼近函数选择的影响。借助 Rayleigh-Ritz 程序检查了三种类型的函数，即振动、屈曲和多项式方法，发现多项式方法函数可产生最佳结果，而屈曲方法被证明不适合屈曲后行为。
The influence of the choice of approximating function for the axial displacement in nonlinear analysis of isotropic simply supported beams on an elastic foundation was studied. Three types of functions, namely the vibration, buckling and polynomial approaches, were examined with the aid of the Rayleigh-Ritz procedure, and the polynomial approach function was found to yield the best results, while the buckling approach turned out to be inappropriate for the post-buckling behavior.
