Abstract

The invention discloses mechanical experiment equipment and a using method thereof.The mechanical experiment equipment comprises an experiment area and an electric control area, a soft plate is arranged in the experiment area, a plurality of models are movably inserted into the soft plate, the lower end of the soft plate is connected with a rotating plate, the lower end of the rotating plate is connected with a rotating shaft, the rotating shaft penetrates through the experiment area to be connected to a rotating device arranged in the electric control area, and the rotating device is connected to a controller; the controller is arranged in an electric control area, the electric control area is further provided with a draught fan, and the draught fan is connected to the air distribution box through a pipeline. The method has the advantages that the model is placed on the soft board, and the model can be quickly assembled and disassembled; a pressure sensor is arranged inside, and the pressure sensor is placed and fixed on the model, so that pressure data can be quickly obtained; air is discharged through the air distribution box, the air distribution box can move up and down, the air outlet height is adjusted, the rotating plate is matched to drive the model to rotate, and the environment is simulated more truly.

Description

technical field [0001] The invention relates to a mechanical experimental device and a method of using the same, belonging to the technical field of experimental devices. Background technique [0002] The patent No. 202111441381.3 discloses a high wind environment simulation test box based on computational fluid dynamics, which adjusts the size of the air outlet by adjusting the components, obtains different wind speeds under the same air volume, and then according to the different wind speeds or different wind speeds. Simulation data to ensure the accuracy of the simulation data, thereby ensuring the rationality of architectural or urban planning. However, there are the following problems: 1. The wind direction cannot be adjusted; 2. The pressure data cannot be directly obtained; 3. The model layout is cumbersome to load and unload. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a mechanical experimental equipm...
