最近几年压力阀在各种力的控制系统上开始试用,如:轿车刹车试验器、轮胎防爆试验器、轴承试验器、轧钢试验机等等,但用得最多的收效最好的还是飞行模拟器中的负载模拟系统,其原理如图10所示。由于采用压力阀使系统大大简化,并且产生的多余力(干扰)明显的减小,如图11所示。这样大大提高了试验精度和可靠性。但遗憾的是由于供不应求,使压力阀的广泛使 In recent years, the pressure valve in a variety of force control system to start the trial, such as: car brake tester, tire explosion tester, bearing tester, rolling test machine, etc., but the most used most effective or flight simulation Load simulation system in the device, the principle shown in Figure 10. The use of pressure valves greatly simplifies the system and produces a significant reduction in excess (interference), as shown in Figure 11. This greatly improves the test accuracy and reliability. Unfortunately, due to the shortage of supply, the pressure valve is widely used
