Principle Scheme Design of Mechanical Systems Based on Energy Interaction Model

在分析机械系统能量行为的基础上 ,建立了机械系统能量交互模型 ,并导出其原理方案设计模型 ,从而将系统原理方案设计转换为系统能量函数关系的求解问题 ;提出了能量函数表达系统原理的方法 ,运用键合图法对系统和元件的能量函数建模 ;研究了单输入单输出机械系统的原理方案设计 。

The energy behaviors of mechanical systems were analyzed and a general energy interaction model of mechanical systems was presented. Based on the energy model, the principle scheme design of mechanical systems can be transformed into the solving of the energy relation of the systems. A concept of energy functions for representing the physical principle was proposed and modeled with the language of bond graphs. Then a scheme tree-based reasoning strategy was also presented for solving principle schemes of single-input and single-output mechanical systems. Finally, a design example is given to demonstrate the design model and solving strategy.
