摘要
Abstract
For the stability of n-order variable cross-section compression bars,the differential equations concerning the flexible curve equation were established.Based on the boundary conditions of neighbored-order,a critical load coefficient equation was built by solving the differential equations. And Newton iteration method was applied to calculate the critical load.As a case of telescopic boom for 1200 ton all-terrain crane,comparison results of calculation were analyzed among Newton iteration method,secant method and stability of ANSYS,which indicate the rationality of the critical load coef-ficient equation and efficiency of Newton iteration method.关键词
