纤维复合材料层合板的刚度、稳定性及振动等问题都是设计中必须考虑的问题,国内外学者对“双向铺设”层合板考虑稳定、自振频率及弯曲挠度的铺层优化设计曾进行过研究,他们都是以各层板的铺设角为设计变量,然后用 Powell法或变尺度法逐次改变设计变量搜寻各层板的最优铺设角。 The stiffness, stability, and vibration of fiber composite laminates are issues that must be considered in the design. Domestic and foreign scholars have conducted optimizations on the layered optimization design for “bidirectionally laid” laminates considering stability, natural frequency and bending deflection. In the study, they used the laying angle of each lamina as a design variable, and then used the Powell method or variable-scale method to change the design variables one by one to search for the optimal laying angle of each lamina.
