摘　　要：在飞机维修仿真中,针对航空电子组件仿真模型不统一、重用性差的问题,提出基于SCM(simulation component model)的规范化建模方法建立组件模型。采用SCM规范定义模型框架后,依据航空电子组件在维修过程中的特性和功能,将组件的输入信号归纳为开关量输入、功能信号输入、故障信号输入和拆装信号输入四类,输出信号定义为功能信号输出和驱动信号输出两类,然后进一步界定了模型输入信号、控制信号和输出信号之间的运算规则,以满足组件操作、测试、拆装、排故等维修行为。最后,以飞行增稳计算机组件为例,在自制的飞机维护训练器上实现其模型化表达,仿真结果表明该方法可行。A normalized method was proposed based on simulation component model（ SCM） for describing avionics in aircraft maintenance simulation process.This method can solve the problem of poor reusability within the existing component models.The component model is built according to the modeling specification and framework of SCM.The input and output signals of the modeled component are summed up according to the avionic component＇s characteristics and functions.A set of operation rules are defined between output signals and the other two signals,which are input signals and a return value from dominant functions.The model not only can realize the functional simulation,but also generate the maintenance behaviors such as operation,test,removal,installation and troubleshooting.At last,the feasibility of this modeling method is verified on the self-researched aircraft maintenance simulator by taking the flight augmentation computer for example.
