基于ABAQUS的柔索承载梁的受力分析

MECHANICAL ANALYSIS OF BEAM SUPPORTED BY CABLE BASED ON ABAQUS

为研究以柔索承载的梁,拟减小柔索位移大的劣势,继承柔性光伏支架跨度大的优势,以柔索承载的简支梁在均布荷载作用下的内力和变形量为研究对象,通过数值计算及ABAQUS数值模拟研究的方法,对比理想简支梁和作为次梁时的简支梁的数值模拟和理论计算的结果,并对3种状态下简支梁的内力大小和变形模态进行分析,相互论证;然后用相同方法对连续梁进行了模拟分析。研究结果表明:柔索承载的简支梁其受力形式、内力大小及变形情况均接近理想简支梁,连续梁同此结论。研究结论为光伏柔性支架中以柔索承载的梁的设计方法和工程应用提供了理论和计算依据。

The research purpose of this papor is to reduce the disadvantage of large displacement of cable and inherit the advantage of large span of ftexible PV support for beam supported by cables.Research on the internal force and deformation of simple beam supported by cables under uniformly distributed load,numerical calculations and ABAQUS numerical simulation research methods are used to compare the results of numerical simulation and theoretical calculation of ideal simple beam and a simple beam as secondary beam.Then,the internal force magnitude and deformation modes of the simple beam under three different states are analyzed and mutually demonstrated.Simulate and analyze continuous beam using the same method.The research results show that the force form,internal force size,and deformation of simple beam supported by cable are very close to ideal simple beam,continuous beam is also,providing a theoretical and calculation basis for the design method and engineering application of beam supported by cable in flexible PV support.
