Problems solved by technology

However, since the reflective plane mirror and the soap film are on the same plane, the reflector mounted on the cantilever beam needs to pass through the plane of the soap film and be arranged in front, so that the displacement recording device of the laser point (that is, the camera device of the dynamometer system) and the soap film flow The field camera device needs to be misplaced, which brings a lot of inconvenience to the experiment

Abstract

The invention discloses a Single degree of freedom micro force measurement system for soap film water tunnel model experiment, related to the field of experiment equipment of experimental fluid mechanics. The system comprises an upper water storage device, a valved flowmeter, a recording camera, a second reflecting plane mirror, a first reflecting plane mirror, a laser emitter, a main camera, a lower water storage device, an upper water pump, a support frame, a receiving plane, a six-degree-of-freedom adjustor, a cantilever, a model support device, a soap film and an experimental model. The first reflecting plane mirror is parallel to the second reflecting plane mirror, the first reflecting plane mirror and the second reflecting plane mirror are perpendicular to the soap film; the main camera and the recording camera are arranged at two sides of the soap film; the cantilever is fixed on the six-degree-of-freedom adjustor; the six-degree-of-freedom adjustor is fixed on the frame of a soap film apparatus, and is located behind the soap film. According to the system provided by the invention, spatial arrangement of the force measurement system is changed, a real displacement value ofa laser point is obtained more accurately, and experiment precision is improved.

Description

technical field [0001] The invention belongs to the field of experimental fluid mechanics, and relates to a single-degree-of-freedom micro-force measurement system used for a soap film water tunnel model experiment. Background technique [0002] The soap film water tunnel device is a typical experimental device for simulating a two-dimensional flow field. 6 times. The theory proves that the motion of the soap film follows the incompressible N-S equation when the speed of the soap film is much smaller than the propagation speed of the Marangoni wave. The device has the advantages of simple operation, convenient maintenance, good repeatability, stability and reliability, and is widely used in two-dimensional flow field experiments. [0003] The current soap film water tunnel device can well use the monochromatic light interferometry to display the characteristics of the flow field, and record the motion of the experimental model object in the flow field through a high-speed ...
