In 1966, Ross solved the equation of symmetrical free vibration and got six matching solution, but he believed that it is impossible to find a solution which is useful in everywhere. In 1979, Goldenveizer printed a monography in which the uniformly valid representations of curved solution were published, but the representations of membrane solution were still not found. In 1988, Ruo-jing Zhang published the uniformly valid representation of six solutions for symmetrical free vibration and eight solutions for dissymmetrical free vibration for the first time.
但却碰到巨大困难。1966年,Ross给出了轴对称振动的6个匹配解,但却认为不可能求出全域一致有效解。1979年,Gol&denveizer等出版专著,给出了弯曲解的全域一致有效表达式,但仍然没有得到6个解中奇异薄膜解的全域一致有效表达式。1988年,张若京在其博士论文中第一次给出了轴对称6个解和非轴对称8个解的全部&全域一致有效表达式。

In the buckling question under nonconservation force,a simply example( the dynamic stability question under the uniformly follower forces with small deformation % linear elastic, straight normal.) is considered.The variational equation of braid composite cylindrical shells subjectd to uniformly follower forces is deduced based on the variation principle of quasinatural frequency of elastic nonconservative system self-excited vibration.The calculated formulas of the flutter load and quasinatural frequency of shells are obtained. The program for calculating the flutter load is developed.The numerical example is given and some useful conclusions are obtained.
