Abstract

Abstract

The load-bearing capacity and shock response of a state-of-the-art non-fracture super-zip separation device have been analyzed. Based on the static load-bearing analysis, the relationship between the meshing angle and the load-bearing capacity of the non-fracture super-zip separation device has been obtained. The results show that load-bearing capacity is inversely proportional to the angle of meshing teeth and that the critical meshing angle for reliable load-bearing is the self-locking angle of meshing teeth when the friction coefficient of the contact surfaces is constant. By means of the dynamic response analysis, the separation shock responses of the separation devices with different configurations have been gotten. The results show that the two kinds of non-fracture separation devices with different meshing angle can be separated under lower inner pressure compared with the conventional super-zip separation device, and that the peak values of the acceleration history curves of the non-fracture separation device with 5.7° meshing angle configuration are smaller than those of the conventional super-zip separation device at the same measuring points in all three directions.
