Understanding the Effects of Bolted-Joint Attachments and Their Use in Underbody Blast Applications
Abstract
The use of semi-permanent attachments such as bolted joints provides many benefits when adding underbody protection to military vehicles. The use of screws and bolts enable a large amount of flexibility. However, it also identifies a large amount of design related unknowns: How strong does the attachment point need to be? How much load do the bolts take during the blast event? Do they just need to hold the kit in the correct position for the mine engagement or do these bolts need to stay on for the entire engagement? Can the bolted joint alter the boundary conditions of the underbody kit and the hull structure such that it reduces the intrusion into the vehicle occupant area or reduces the global vehicle response of the mine onto the vehicle structure? The focus of this effort is to determine the effect of bolt strength on the underbody kit interface to the hull structure with respect to the intrusion caused by deformation into the occupant area and the global response on the vehicle structure to enable more efficient underbody kit designs for increased occupant protection in ground vehicles.
