Abstract

The invention provides a quasi-three-dimensional automatic measurement system for wind tunnels of an atmospheric boundary layer, relating to a quasi-three-dimensional automatic measurement system. The quasi-three-dimensional automatic measurement system is used for solving the problems that the continuous multipoint measurement and automatic motion of a velocity rod can not be realized because the existing large-sized wind tunnel mobile control equipment is relatively few in category and complicated in structure, automatic equipment is mostly imported from abroad, high in cost and inconvenient in popularization and application, and own equipment is mostly equipment of manual control. The quasi-three-dimensional automatic measurement system comprises a forward-backward moving device and an upward-downward moving device; the upward-downward moving device is arranged in the forward-backward moving device; a first forward-backward moving mechanism and a second forward-backward moving mechanism are arranged at the two sides of a forward-backward moving bracket in parallel; an upward-downward moving bracket is arranged in the forward-backward moving bracket; and a first upward-downward moving mechanism and a second upward-downward moving mechanism are arranged at the two sides of the upward-downward moving bracket in parallel. Support frame length adjustment members and measuring rod support mechanism length adjustment members are adjustable within a certain range of length and can carry out leveling to a certain degree. The quasi-three-dimensional automatic measurement system is applicable to the automatic measurement of the wind tunnels.

Description

technical field [0001] The invention relates to a quasi-three-dimensional automatic measurement system, in particular to a quasi-three-dimensional automatic measurement system for an atmospheric boundary layer wind tunnel. Background technique [0002] A wind tunnel is a pipeline-shaped experimental device that can artificially generate and control airflow to simulate the flow of gas around objects, measure the effect of airflow on objects and observe physical phenomena. It is the most commonly used and most effective for aerodynamic experiments. Tool of. With the development of industrial aerodynamics, low-speed wind tunnels (wind tunnels whose Mach number M is less than 0.4 in the experimental section of the wind tunnel) are becoming more and more widely used in transportation, housing construction, wind energy utilization, and environmental protection. application. In wind tunnel experiments, the model or object is often fixed in the wind tunnel, the gas flows through t...
