摘要
设计了中高压水射流反推力测试系统,介绍了测力原理,研究了测试系统的动态特性,并分析了密封圈对系统性能的影响。结果显示,最大超调量以及调整时间均随输入反推力的增大而减小;系统存在稳态误差,但可以通过测量静摩擦力来补偿。
The design and measuring principle of mid-/high-pressure water jet reaction thrust system was introduced. The dynamic performance was studied, and the effects of seal ring to system performance were analyzed. The results show that maximum overshoot and setting time are both reduced with the increase of reaction thrust and that steadystate error exists in the system. But the steadystate error can be compensated by the static friction.
