【Abstract】 this paper analyses the forces in a giant slap door with impact theory and obtains the conditions that the top hinge refrains from impact when the door is opened.How the exhausts affect the reaction of the top hinge is also discussd.Hence this paper offers basis for optimizing the design of slap door.更多还原
