Abstract

The invention discloses a testing device for measuring hydrodynamics of a liquid tank. The testing device comprises a measuring vehicle. A first connecting plate is mounted at the bottom of the measuring vehicle, and the first connecting plate is connected to a force measuring instrument; a strain gauge is provided inside the force measuring instrument; a second connecting plate is connected to the end, far away from the first connecting plate, of the force measuring instrument; a threaded hole is formed in the second connecting plate. The measuring vehicle is fixed on a vibration table through a main fixing screw; the main fixing screw penetrates through the vibration table from the bottom of the vibration table, and the main fixing screw is screwed into the threaded hole and abuts against the bottom of the measuring vehicle. A laser displacement sensor is mounted at one end of the measuring vehicle; a reflecting plate is provided in the range of the laser displacement sensor; the liquid tank is rigidly connected to the upper portion of the measuring vehicle. The invention also discloses a method for the testing device, which performs data processing according to a physical formula to obtain the hydrodynamics in the liquid tank, and makes up for the blank of the instrument for measuring the hydrodynamics in liquid tank sloshing at a laboratory.

Description

technical field [0001] The invention relates to the measurement technology of liquid tank hydrodynamic force, in particular to a test device and method for measuring liquid tank hydrodynamic force. Background technique [0002] Tank sloshing research was initially carried out in the fields of aerospace and nuclear industry, and then researchers began to study liquid sloshing problems. The study of liquid sloshing is mainly to understand the movement of the liquid in the liquid tank and the pressure acting on the bulkhead during the sloshing process. However, in the field of tank sloshing research, the analysis of the pressure acting on the bulkhead is often to measure the pressure values ​​at multiple points on the bulkhead and compare them with the mathematical model. If the measured point pressures are consistent, then deduce The hydrodynamics in the model correspond to reality. However, based on whether the derived hydrodynamic force is really accurate, it needs to be c...
