Abstract
There are many experimental studies of the measurement of the water impact load. Pressure sensors are widely used to measure the water impact load, but there are few papers handling the characteristics of the pressure sensor thoroughly. The present study investigates the characteristics of the pressure sensor for the measurement of the water impact load. For this purpose, seven pressure sensors are attached to a 2D wedge surface, and the water impact pressure is measured during the free falling of the wedge. Those pressure sensors have different types, sensing areas, and sensitivities. The peak pressures, rise times, and pressure impulses measured by the different types of pressure sensors are compared with one another. On the basis of these results, the characteristics and reliability of the pressure sensor for the measurement of the water impact load are discussed.
