基于有限元模型的木结构规格材可靠度研究

he finite element method was used to simulate the unit selection and material properties of the wood properties. Through the comparative analysis of test results and the finite element analysis, relative error less than 5%. The calculation of the bending deformation and specification material stress analysis is effective based on the finite element reliability analysis of ANSYS software; the structural reliabilities of 750mm *40MM * 40MM wood structures were calculated. In the practical structural design and component size design, the corresponding trend of the deformation and stress distribution can be taken in a certain number of samples of the test specimen, by inputing the sample average of the elastic constants and corresponding to load, , that can provide the reference for the design.
