- 摘要:
- 介绍了推力测量传感器并联工作原理，进一步确定并联作为液体火箭发动机试验推力测量中多只传感器的电路连接方法。通过对多只传感器并联的选配与分析，在保证灵敏度与输出阻抗比值一定的情况下，该方法可以提高推力测量精度，同时输出力值不受偏心载荷影响。
- Abstract:
- The mechansim of parallel connection mesurement is presented. Parallel sensors are chozen as the measurement method in liquid propellant rocket engine tests. Multiple sensors connections are analyzed and tested. The analysis and test results show that parallel connection measurement of thrust sensors can improve the measurement precision and eccentric load has little effect on the result.
