摘要: 研究探针测定水流场针孔压力测量反应时间的影响因素,给出探针测试系统合理参数,分析探针杆水力共振和受水绕流阻力挠曲的影响,提出相应对策,以提高测试精度。Abstract: The factors were studied that affect reacting time of hole pressure of a probe measuring water flow field. The reasonable parameters of combined probe measuring system was presented. The influence was analysized of probe hydraulic resonance and bending under circufluent drag on the measurement. The countermeasures were advanced to improve the measuring precicion.
