摘　　要：文中采用数值模拟优化设计了耐温承压超声探头,并对探头进行了耐温承压(30~60℃,1.0~1.6MPa)和线性误差分析的实验研究。结果表明,计算得到探头外壳底部最优厚度为1.05mm,最优隔热层厚度为0.2mm。随着外界介质压力值和温度变化,其检测最大误差值分别为3.2%和3%。探头在水和原油中的线性实验最大误差分别为9%和10%,满足原油管道测量精度的要求。In this paper,the temperature-resistant and pressure-bearing ultrasonic probe was designed and optimized by numerical simulation,and the temperature-resistant and pressure bearing (30~60℃,1.0~1.6MPa) and linear error analysis were carried out.The results show that the optimal thickness of the bottom of the probe shell is 1.05 mm,and the thickness of the optimal insulation is 0.2 mm.With the external medium pressure and temperature changes,the detection results of the maximum error value were 3.2% and 3%.The maximum errors of the linear experiment of the probe in water and crude oil were 9% and 10% respectively,which meets the design requirements of the measurement accuracy of crude oil pipeline.
