把流动坐标原点设在球囊中心,探讨了用充气薄膜球囊测量流体压力的数学方程,提出了应优选圆球囊测压,并分析了测压误差及误差处理方法,绘出了仿真曲线与实验曲线,通过实验验证了仿真的正确性.
The origin of the flow coordinate is set at the center of the balloon. The mathematical equation for measuring the fluid pressure with the inflation membrane balloon is discussed. It is suggested that the measurement of the balloon pressure should be optimized. The error of the pressure measurement and the error handling method should be analyzed. With the experimental curve, the correctness of the simulation is verified through experiments.
