基于有限元的组合式臂架等效惯性矩计算方法研究
摘要
Abstract
The paper puts forward the calculation method of equivalent inertia moment of combined boom based on fi -nite element , to convert the stability calculation of variable-rigidity combined component into the equivalent calculation of constant-rigidity component , hence to figure out the equivalent Euler critical load of the combined component.As a result, the theoretical value of buckling stability coefficient is consistent with the bulking coefficient through finite element bulking analysis.The calculation method is verified for its correctness through site test.关键词
