摘要
用微分求积法分析了一端固支一端具有弹性支承的双参数弹性地基上输流管道的稳定性问题.得到了不同无量纲地基反力系数和无量纲地基剪切模量下输流管道的稳定性区域图,指出了弹性支承常数,地基反力系数和地基剪切模量对管道稳定性的影响.
The stability of pipe conveying fluid with one end clamped and the other spring support on the twoparameter elastic foundation is studied by the differential quadrature method. Then, the stability regional graph of pipe conveying fluid is given for the different dimensionless reaction of the foundation coefficient and the different dimensionless shear modulus of the foundation and effects of elastic coefficient of spring support, the reaction coefficient of the foundation and shear modulus of the foundation on stability of pipe conveying fluid are analyzed.
