EVALUATION METHOD FOR FASTENING PART WITH SLACKENING STOPPING FUNCTION FOR FASTENING MEANS, AND DESIGN METHOD FOR FASTENING PART OF FASTENING MEANS BASED UPON EVALUATION METHOD FOR THE FASTENING PART

摘要

PROBLEM TO BE SOLVED: To provide an evaluation method for a fastening part with a slackening stopping function for fastening means, and a design method for the fastening part of the fastening means based upon the evaluation method for the fastening part.;SOLUTION: There is provided an evaluation method for a fastening part with a slackening stopping function for fastening means. The evaluation method includes: a first step S1 of mounting the fastening part having the slackening stopping function on the fastening means, conducting a slackening test while placing a load in an axis orthogonal direction of the fastening means, and acquiring slackening occurrence presence/absence data through FEM analysis; a second step S2 of generating a desired multidimensional response curved plane from predetermined design specifications and various conditions; and a third step S3 of plotting desired design specifications of the fastening part on the response curved plane and evaluating whether slackening occurs.;COPYRIGHT: (C)2014,JPO&INPIT
