A port tyre crane has various parts and complex structure, which is made up plenty of beam - bar and shell elements, manual calculation can not guarantee the precision while finite element method needs onerous structure modeling and a great deal of date input. the finite element analysis and modeling of the port tyre crane are difficult because of complex structure and various loads. in order to fit further more design and exploitation of the same type as well as the upgrade of the production i study a kind of parametric software for structure analysis of the port tyre crane, it can reduce the difficulty of modeling and structure analysis as well as improve efficiency
港口輪胎式起重機部件繁多、結構復雜，由數目眾多的梁桿與板殼組成，其結構設計和力學分析使用傳統的手工計算方法難以保證精度，有限元方法則需要繁重的結構建模和大量的數據輸入，並且要求分析人員具有相當的力學知識和有限元基本理論。港口輪胎起重機結構的復雜性、載荷工況的多變性導致港口輪胎起重機結構有限元建模和分析工作效率低、難度大。針對這種情況本課題研發了一套港口輪胎式起重機結構的有限元參數化分析軟體，以適應同類機型的進一步設計開發和產品升級換代，降低建模和分析的工作難度，提高工作效率。
