Design and Development of a Kind of Instant Opening Door Locking Mechanism
Aiming at the slow response speed of instantaneous door opening of a large-scale DC suction wind tunnel,which af-fects the quality of the flow field,a locking mechanism with instant response is designed.Numerical simulation of the actual work-ing process of the locking mechanism designed in this paper is carried out.By setting constraint conditions and comparing the sim-ulation results,the size parameters of the locking mechanism are optimized,and a two-way locking method is proposed,which adopts cylinder control and has an automatic locking function.Finally,a physical prototype was developed according to the opti-mized parameter size,and the structural strength and rationality of the locking mechanism were verified through tests,and the comparison test of the opening time data was carried out,and the instant opening time of the door was only 120ms,380ms is re-duced on the basis of 500ms for the original opening.
