摘要
简单阐述机械阻抗与键图二者的主要特点之后,着重分析两个问题:①机械阻抗法与键图二者的共同特点;②键图利用状态变量建立状态方程组,经拉氏变换后求得传递函数,应用于复杂系统时具有简便的特点.
After a brief introduction of both the mechanical impeadance method and bond graph, two problems are discussed:(1)the common features of above-mentioned methods;(2)us- ing the state variables and state equations,after the Laplace transform,bond graph method can be applied to complex mechanical system with simple and convenient advantages.
