面向半实物仿真的液压起落架信号模拟系统设计与实现

摘要

To provide all of the avionics signals and flight control signals to the model of control system of landing gear in the Hardware In the Loop (HIL) simulation of the hydraulic landing gear, a signal simulation system was designed and implemented in the LabWindows/CVI platform with ARINC429 board. The results of the joint commissioning test with a simulation target show the effectiveness of simulation system, which provides a method for simulating signals of hydraulic landing gear in HIL.%为在起落架系统的半实物仿真中模拟起落架控制系统所需的所有航电、飞控信号,利用ARINC429板卡,在LabWindows/CVI平台上设计实现了液压起落架信号模拟系统.通过与仿真目标机的联合调试,验证了模拟系统的有效性,为起落架系统的半实物仿真模拟信号提供了一种方法.
