六十年代中期以后,国外已进入自动分析设计时期。由于电子计算机和各种应用软件的飞速发展,再加上各种实验技术,实验设备的不断更新,使得产品设计成功率高达90％左右,其中结构分析通用程序和各种专用程序,对产品的静动力分析起了很大作用。国外许多公司几乎都普遍采用计算机来分析,计算各类产品的性能。应该看到,电子计算机和各种程序的迅速发展,实际上已引起了设计分析上革命性的变化。一、国外大型结构分析有限元通用程序概况
After the mid-1960s, foreign countries have entered the period of automatic analysis and design. Due to the rapid development of electronic computers and various kinds of application software, together with various experimental techniques and experimental equipments, the success rate of product design is as high as 90%. Among them, structural analysis general programs and various specialized programs, Static and dynamic analysis played a big role. Almost all foreign companies generally use computers to analyze and calculate the performance of various products. It should be noted that the rapid development of electronic computers and various programs has in fact caused revolutionary changes in design analysis. First, foreign large-scale structural analysis of finite element general procedure overview
