井架结构力学性能的有限元分析

FEM Analysis of Mechanical Behavior of Derrick

介绍了有限元法用于结构计算的基本原理,并通过一个工程实例,应用大型通用有限元软件ANSYS对井架结构的力学性能进行了分析,获得了在计算荷载作用下井架的最大应力与位移,并求得了井架结构的失稳荷载,为井架结构的设计提供了有价值的理论依据,为以后的井架设计提供了一种非常有效的计算方法。

The basic principle for structure computation by FEM is introduced, and through a project example of a derrick, whose structural mechanical behavior is analyzed through large- scale general FEM software ANSYS, consequently the maximum stress and displacement and critical load under the load are obtained, which provides a valuable theory basis for the derrick structure design. At the same time, it provides one extremely effective computational method for later derrick design.
