METHOD FOR IMPROVING DYNAMIC RIGIDITY AND DAMPING CAPACITY WHILE MAINTAINING AND IMPROVING STATIC RIGIDITY OF COUPLED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for improving a dynamic rigidity and a damping capacity while maintaining or improving the static rigidity of a coupled portion.;SOLUTION: There is provided a method including the steps of: preparing a coupled structure with a first member, a second member, an elastic member, and a fastening member; regulating an interference between the first member and the second member; and arranging the elastic member between the first member and the second member to fasten the first and second members using the fastening member so that a first abutting surface and a second abutting surface abut against each other at given coupling contact pressure. At this time, the interference and the given coupling contact pressure are regulated so that the equivalent rigidity of a coupling portion is equal to or more than that obtained when the elastic member is not interposed therebetween and an equivalent viscous damping coefficient increases.;COPYRIGHT: (C)2014,JPO&INPIT
