Model making system for physical similar simulation experiment

Abstract

The invention relates to a model making system for physical similar simulation experiment. The model making system includes an experimental box and a tamping device installed on the experimental box. Two rows of racks parallel to each other are mounted at the upper end of the experimental box, the tamping device includes a tamping impact head, impact air cylinders, a connecting steel plate, a tamping connecting plate, a walking pneumatic motor, walking gears, a feed chute, guide rods, a distance adjustment stud and a distance adjustment pneumatic motor. The front ends of the impact air cylinders' piston push rods are fixedly connected to the tamping impact head, the bottom end of the tamping connecting plate is disposed on the upper part of the experimental box through the walking gears, the walking gears are engaged with the racks, the tamping connecting plate is equipped with the walking pneumatic motor controlling gear advancing, the upper end of the impact air cylinder at the middle of the connecting steel plate is fixedly connected to the distance adjustment stud, and the upper ends of the remaining impact air cylinders are fixedly connected to the guide rods. The model making system provided by the invention can complete the tamping work of an experimental material, alleviates the labor intensity, and makes an obtained experimental model have a higher similarity level with a prototype.

Description

technical field [0001] The invention relates to the technical field of physical similarity simulation experiments, and in particular to a model making system for physical similarity simulation experiments. Background technique [0002] my country is the world's largest coal-producing country, with coal output accounting for 48.3% of the world's total. At the same time, coal is my country's main energy source, accounting for 76% and 69% of the total primary energy production and consumption respectively. However, my country is also a country with a high incidence of coal mine accidents. Accidents such as water, fire, gas, and roof seriously threaten the life and property safety of mine operators. In order to effectively curb the occurrence of coal mine accidents, scholars have conducted a large number of experiments to study the occurrence of disaster accidents, and physical similarity simulation is an important means. [0003] The physical similarity simulation experiments ...

Problems solved by technology

However, at the present stage, in the process of making experimental models, most of them are carried out manually, and human uncertain factors bring uncertainty to the making of experimental models, so the mechanical parameters of the model cannot be accurately controlled, and manual work is labor-intensive.
