摘　　要：分析了杨木—秸秆层合梁在弯曲变形中的失效情况,并根据实际需要,在层合梁结构总厚度一定的情况下,以梁的弯曲变形和弯曲应力为约束,以减少复合结构的总质量为目标,利用ANSYS有限元工程分析软件对梁的横截面结构尺寸进行优化设计。The failure intensity of poplar-straw laminated beam caused by bending deformation is analyzed. According to actual needs, with the total thickness unchanged and with the bending deformation and bending stress as restriction, the optimum design of the structure size of the cross section of the beam is made, using ANSYS finite element program, in order to reduce the total mass of the beam.
