摘要
研究了蜂窝地板在弯曲载荷作用下的失效形式,并基于失效因子建立了优化模型。根据地板结构的优化设计准则,以地板的高抗弯刚度、高强度要求、高固有频率和小质量为目标函数,以稳定性、屈曲极值、剪切强度和刚度为约束条件,构造了评价函数,得出了最优尺寸以及对应的力学性能参数。最后利用强度计算公式对该设计进行了校核,计算结果表明,优化后的蜂窝集装箱地板能满足使用要求。
Main failure modes of honeycomb flooring undergoing bending load were studied and an optimization model based on failure factors was set up.According to the optimization design criterion of the flooring structure,the evaluation function based on four objective functions was constructed,which were high flexural rigidity,high strength requirement,high inherent frequency,and low mass of the flooring,with four constraint conditions,which were stability,buckling extreme,shear strength,and stiffness.The optimal value of dimensional parameters was obtained and the parameters of mechanical property were calculated through them.Strength calculation formula was utilized to check the strength of the structure.The computational results showed that the optimized honeycomb container flooring meets the application demand.
