摘　　要：利用高刚度弹簧,提供负载推力,推力传感器和光栅传感器进行推力和位移检测,设计一种直线运动的通用直线弹性负载加载设备,广泛应用于飞机、运载火箭等襟翼驱动伺服系统、火箭发动机喷管摆动伺服系统等大推力直线弹性负载能力和控制精度测试。试验结果表明,该加载测试台通过调节弹簧压缩量,截取弹簧不同位置的推力段,可以有效地模拟系统的负载特性。显著改善了测试工况,降低了测量误差,提高了试验结果的准确性,并缩短了测试时间,提高了测试效率。Using high-stiffness spring to provide the load thrust, and adopting the thrust sensor and grating sensor to detect the thrust and the displacement, we have designed a general linear elastic load loading equipment, which can be widely used in the aircraft flap driven servo system, the carrier rocket engine nozzle swing servo system and other large thrust linear elastic load capacity tests and precision tests.The test results show that, by adjusting the amount of spring compression and intercepting the thrust at different position of the spring, the test equipment can effectively simulate the system load characteristics, which significantly improves the test condition, reduces the measuring error, improves the test accuracy, shortens the test time, and improves the test efficiency.
