鉴于机械自动化、高速化精密化的要求,机械系统的参数设计,不但要考虑它的静态性能,而且要研究它的动态性能。一些机械系统之所以不成功,往往是由于对系统的动态特性缺乏正确的描述和分析,使系统的某些参数和结构得不到正确的选择而引起的。将实际系统或设想的方案,按其组成元件的动能简化成易于研究的、合理的动态教学模型,这是系统动态设计的关键。本文讨论单变量线性定常机械系统的教学模型传递函数。
In view of the requirements of mechanical automation and high-speed precision, the parameter design of mechanical system must not only consider its static performance, but also study its dynamic performance. Some mechanical systems are unsuccessful, often due to the lack of proper description and analysis of the dynamic characteristics of the system, so that some of the system parameters and structures can not be the correct choice. The actual system or envisaged program, according to the kinetic energy of its components simplified into an easy-to-study, reasonable dynamic teaching model, which is the key to dynamic system design. This article discusses the teaching model transfer function of a univariate linear stationary mechanical system.
