6-component force measuring device for measuring fluid force acting on an elongated model

摘要

To improve the accuracy of measurement with a six-component force measuring device in a fluid force measurement test of a slender model of a hull or a vehicle so that the deformation that occurs in a slender model is not applied to the detection unit of a multi-force detector.SOLUTION: A six-component force measuring device comprises a first link mechanism (21), a second link mechanism (31), and a third link mechanism (41) that support a measurement device main body (60). Each link mechanism comprises a combination of universal joints and bearings so that the force and moment generated in accordance with the deformation generated in the slender model when the fluid force or the forced excitation force is received are not transmitted to the detection unit for the six-component force measurement. It has a three-component force detector (2) for F, Fand Mdetection between the first linkage mechanism and the above-mentioned main part, a two-component detector (3) for Fand Fdetection between the second linkage mechanism and the above-mentioned main part, and a one-component force detector (4) for Fdetection between the third linkage mechanism and the slender model.SELECTED DRAWING: Figure 1
