基于线性累积损伤的金属结构全场疲劳分析技术

摘要

A way to calculate the whole audience fatigue and the cloud display approach is developed to solve the fatigue for crane metal structure characteristics based on linear cumulative damage theory. The specific process is based on ANSYS software by using its APDL with VC ++. The solution process is automatic to solve the linear cumulative damage theory for whole metal structure fatigue analysis and to obtain the structure of audience fatigue cloud.%基于线性累积损伤理论，针对起重机金属结构特点，提出一种可计算全场疲劳并以云图方式显示的技术方法，以 ANSYS 有限元软件为基础，利用 APDL 与 VC++结合，自动控制其求解过程。解决长期以来疲劳校验只能针对结构某个局部而不能整体分析的问题。
