Analysis of Explosion Impact Force on Explosion-proof Cover

We introduce the working principle and structure of folio and dry explosion-proof cover, and describe the design of the new type explosion-proof cover. Through analyzing the stress relationship of the cover plate when mine gas explosion occurred, we build methematic model of turning torque of cover palte and calculate the turning torque of explosion-proof cover, which provides the basis for motion analysis of explosion-proof and key components design.
