ABAQUS 程序在微机上的移植和开发

TRANSFER AND DEVELOPMENT OF THE PC VERSION OF ABAQUS PROGRAM

概述了大型力学非线性有限元结构分析通用程序ＡＢＡＱＵＳ微机版的移植和开发工作，解决了不同计算机浮点数格式差别、数据传输中的死机等特殊移植技术难题，并通过二次开发给程序增加了可视化输入输出功能，既降低了分析工作的劳动强度，又保证了计算的可靠性。微机版ＡＢＡＱＵＳ程序通过了原版所附标准例题的验算，结果完全符合。用微机版ＡＢＡＱＵＳ对中国实验快堆（ＣＥＦＲ）壳体进行了强度和变形计算，计算结果亦与ＡＤＩＮＡ程序的计算结果完全一致。

The transfer and development of the PC version of ABAQUS——a large nonlinear mechanical finite element analysis program are carried out. Some special problem such as diffe rence of the floating data format in different computers and the computer's unusual dead halt during the data transfer is solved and the visualized I/O capability is added in the redevelopment.Thus, by utilizing the visual capability, the intensity of analysis works is reduced, and the correctness of analysis is ensured. The PC ABAQUS are tested by the standard examples from VAX verison of ABAQUS and the calculation results are correct.The results of calculation of stress and deformation for CEFR shell structure with PC ABAQUS and ADINA codes agree very well.
