Simulation device for air airflow tripping force experiments of arm

Abstract

The invention discloses a simulation device for air airflow tripping force experiments of an arm, which comprises an integral framework, a wire winding mechanism, a traction mechanism and a switch mechanism, wherein the wire winding mechanism, the traction mechanism and the switch mechanism are connected with a spring through a steel wire rope, the traction mechanism is also connected with an arm protection sleeve through the steel wire rope, and the steel wire rope is tensioned through the wire winding of the wire winding mechanism so as to deform the spring, the steel wire rope connected with the switch mechanism can be separated from the switch mechanism through switching on the switch mechanism so that potential energy stored when the spring deforms can be converted into kinetic energy of the traction mechanism. The traction mechanism slides on the integral framework, and drives the steel wire rope arranged on the arm protection sleeve to pull away the hand for reaching the goal of completing the experiments. The simulation device is convenient to operation, has low cost, conforms to the real ejection condition and can obtain accurate data, and the obtained mechanical data can provide the theoretical foundation for the study of the arm protection measure while the aircrew escape of pilots.

Description

technical field [0001] The invention belongs to the technical field of biomechanics, and relates to a biomechanical experiment simulation device, specifically, a device for simulating the airflow release force of the pilot's arm during ejection rescue, which is suitable for releasing the airflow in the hand of the pilot during ejection rescue force research. Background technique [0002] During the high-speed flight of modern fighter jets, in case of danger, the pilot needs to eject to save his life. In order to make the ejection life-saving system small in mass and good in stability, the existing ejection life-saving system mostly adopts an open ejection life-saving seat. Very serious injuries were caused to the chest, abdomen and limbs. Due to the large range of motion of the upper limbs and the difficulty of fixing them, it accounts for the vast majority of airflow impact injuries. During the ejection, when the hand cannot hold the ejection handle (central ring) and is...
