Outline of Final Research Achievements

To use the the bolted joint,with 2 bolts on the line of load direction, as the device absorbing the energy, we should design the bolted joint to make break the base plate before breaking out the bolt by shearing. We propose the calculating method the tranceffered force by each bolt. Bolted joint for friction type, it is recommended to use 60mm as the end distance especially for the plate with thickness of 9mm in order to increase the pefoemance of deformation and load capacity.
