Analyzed with the developed software, the stress and deformation distributions of f320 derrick and j250 / 42 - k derrick under several working conditions are obtained. the results obtained here are consistent with tha t obtained with supersap93, which illustrates the program is correct and practicable. finally a fem pre - processor and post processor is developed
本論文用編制的程序分析了f320型和jj250 / 42 - k型石油鉆機井架在幾種工況下的應力、變形分佈,及兩種井架的固有模態、屈曲模態和可靠性,所得結果與supersap93的計算結果比較,應力和位移誤差均相差很小,說明本程序系統是正確可行的。
