前言今天,在美国防部的大部分导弹研制计划中,各种模拟技术已起着非常重要的作用。事实上,模拟作为一个技术领域,是由于要求不制造实际系统并进行试验就能确定复杂的导弹制导系统各个部件工作好坏而产生的。用计算机模拟复杂的物理系统,为我们提供了一种手段,利用这种手段,在实际系统交付制造以前,投入适中的资金,我们就能迅速回答许多设计上的问题。使用这种方法,还可以避免许多误差。然而,在历史上,只有在极少数的研制计划中,模拟技术的使用 Foreword Today, various simulation technologies have played a very important role in most of the U.S. Defense Department’s missile development programs. In fact, simulation is a technology area that arose from the need to determine how well the various components of a complex missile guidance system work, without making actual systems and experimenting. Using computers to simulate complex physical systems gives us a means by which we can quickly answer many design problems by investing modest funds before the actual system is delivered to manufacturing. With this method, many errors can also be avoided. However, in history, the use of analog technologies has been simulated only in a very small number of development plans
