Abstract:
These preliminary dynamic tests were run subsequent to the Boydbolt static tests. The purpose was to (1) check out the revised installation technique (procedure 2. 33597 5, Revision C), (2.) examine the Boydbolt with the hardened spindles (CA 2.773-14-1) as compared with the regular bolt (CA 2773-14), and (3) further test the effect of Mylar insulation material on bolt preload.
