机身/发动机数控组件测试系统的研制

针对国内尚未拥有机身/发动机数控组件维修、测试能力的现状，并结合该组件当前故障率，提出一种基于虚拟仪器技术的维修测试平台。该平台以GPIB仪器、VXI模块为依托完成硬件设计，利用labview驱动模块实现对各类测试仪器的控制，并进一步完成软件设计。针对此平台进行误差分析的结果表明：该系统测试精度较高，参数误差均在性能指标范围内，能够满足机身/发动机数控组件的维修测试需求。

Development of Test System for Airframe/Engine Data Processing Unit

Based on the current situation that China is still not equipped with the ability to maintain and test the airframe/engine data processing unit and with the current failure rate of this unit, this paper puts forward a maintenance test platform based on virtual instrument technology. The hardware design is completed based on the GPIB instrument and the VXI model. The labview driver module is utilized to realize the control of various test instruments and further accomplish the software design. An error analysis of this platform is carried out and as indicated by the analysis result, this system testing possesses a relatively high precision. With all the parameter errors within the scope of performance indicators, the system is able to satisfy the maintenance and testing demand of airframe/engine NC unit.
