摘　　要：波浪冲击压力是海洋工程中重要的物理量之一,采用压力传感器测量波浪冲击压力的传统方法测量结果单一、稳定性差,因此需要寻找一种代替压力传感器的新测量元件。本文针对波浪对直立板的冲击模型,利用MFC对该模型的波浪冲击压力进行测量。为了验证该测量方法的可行性和准确性,将MFC测量波浪冲击压力的实测值与海洋工程中常用的经验公式的计算值进行对比。实验结果表明,MFC的测量结果与我国规范的计算结果较吻合;与我国规范相比,5种入射波高产生的所有有效数据中,仅5 cm入射波高平均误差超过10%,为18.25%,12 cm入射波高平均误差最小,最小为2.56%。Wave impact pressure is one of the important physical quantities in ocean engineering.The traditional method of measuring wave impact pressure using pressure sensors has single measurement results and poor stability.Therefore,it is necessary to find a new measuring element to replace pressure sensors.In this paper,MFC is used to measure the wave impact pressure of the model for a wave impact on a vertical plate.In order to verify the feasibility and accuracy of this measurement method,the measured values of wave impact pressure measured by MFC were compared with the calculated values of empirical formulas commonly used in ocean engineering.The experimental results show that the measurement results of MFC are in good agreement with the calculation results of our country's specifications;compared with our country's specifications,among all the effective data generated by the five incident wave heights,only the average error of the incident wave height of 5 cm exceeds 10%,which is 18.25%.The average error of the incident wave height of 12 cm is the smallest,with the smallest being 2.56%.
