FIXING STRUCTURE FOR PARALLEL LEAF SPRING, PARALLEL LEAF SPRING UNIT, MICHELSON INTERFEROMETER AND FOURIER TRANSFORMATION SPECTRUM ANALYSIS APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a fixing structure for parallel leaf spring in which one-side terminals of a parallel leaf spring can be vibrated while maintaining a parallel attitude with higher precision.;SOLUTION: A fixing structure for a parallel leaf spring comprises parallel leaf springs 60 including flat plates 61 and 62, a moving portion 63 and a base portion 64, and fixing sections 50 and 70 which hold the base portion 64 from positions S1 and S2 therebetween and fix the side of another terminal 60B of the parallel leaf spring 60 with a predetermined holding force applied to the base portion 64. In the state of resonating the parallel leaf spring 60, a node N1 of a primary free vibration mode at the other terminal side 60B of the parallel leaf spring 60 is positioned inside the base portion 64. By resonating the parallel leaf spring 60 fixed between the fixing sections 50 and 70, rotation moments RA and RB are generated in the base portion 64, the fixing sections 50 and 70 apply the holding force to the base portion 64 so as to operate the holding force within a virtual plane XY including the rotation moments RA and RB. The positions S1 and S2 are in a point-symmetric positional relationship with the node N1 as a center.;COPYRIGHT: (C)2013,JPO&INPIT
