空腹桁架式桥架有限元计算及分析

Finite Element Caculation and Analysis of the Truss of Crane

建立了空腹桁架式起重机的有限元模型,结合100 t空腹桁架式桥架,明确了几种计算工况,确定了各工况的计算载荷,对强度及应力分布作了综合分析。

The finite element modal of the truss of bridge craneby is constituted ,based on lO0 ton bridge crane, the critical condi-tions under stress are analyzed and the intensity and distortion of the struct are calculated.
