塔机标准节K形杆系的受力分析

Stress analysis of tower crane K bar

对于塔身主弦杆采用方管或圆管的自升式塔机,其塔身标准节顶升面多采用K形杆系。以某型号塔机为例,对标准节K形杆系用有限元方法分析腹杆的受力,对K形杆系的布置、结构形式进行较详细的分析。

For the main chord of tower crane adopt square tube or circular tube of self-lifting tower crane,the tower body standard section jack-up surface with k type truss.In the case of a certain type of tower crane,to analysis the stress of the standard section K type system's web member with finite element method,and make a more detailed analysis of K type truss layout structure.
