Abstract
The finite element model for dent performance of aisle floor in white body was established according to the practical problem.The index of dent performance of aisle floor was obtained according to the calculated result.The results of experiment and finite element analysis method were compared.The comparison results show that they have good consistency.The method of finite element analysis is effective.In order to obtain the optimized parameter combination for dent performance of aisle floor,orthogonal test was established.The research factors were depth of transverse stiffener,material designation and thickness.Each factor was designed in three levels.An orthogonal table L9(34)was built and 9 groups of finite element analysis model were conducted.The analysis results were processed by the variance and range analysis,and the influence of each factor and level for each dent performance index of aisle floor were gained.The optimized parameter combinations are confirmed finally.Design references for dent performance of aisle floor are provided,and it has significance in application.关键词
