摘要：节气门用来控制汽车的进气量，其性能的好坏直接影响到发动机的燃油效率和动力性。基于对节气门的功能和耐久性试验方法的研究分析，以美国国家仪器公司（NI）的软硬件开发环境为基础，开发了对节气门的位置传感器、怠速执行器和气门体的试验台。测试台以机械加载结构模拟了实际发动机系统中管路两侧压差对节气门叶片轴形成的作用力，使试验条件高度还原实际状况，提高了试验结论的正确性。

Abstract: The throttle controls the air input of the automobile engine. The performance of the throttle has a direct effect on the engines fuel efficiency and dynamic. Based on the analysis of testing methods for throttles function and endurance, this system, which can be used to test the endurance and reliability of the throttle body and its position sensor as well as the idle speed actuator, was developed with NI LabVIEW and corresponding hardware. Furthermore, an especial mechanical structure was used in the system to simulate the acting force on the rotational axis, which would be caused by the pressure difference between both sides of the throttle in real conditions. In this way, the accuracy of test conclusion can be improved.
Key words: throttle; test bench; endurance; virtual instrument; LabVIEW
