ばねの自由形状はばね特性解析に不可欠である.一般的に自由状態を求めるには,幾何学非線形と材料非線形の両方を用いなければならない.しかし,本報告ではアフィン線形に基づいて,幾何学的非線形がいらない新しい手法を提案する.

Summary

For the purpose of analyzing the characteristic of spiral spring, knowing the free shape of spring is indispensable. And to get the free shape of spring needs to analyze on elasticplastic method with geometric non-linearity. But the practical importance for the spring characteristic is the liner zone without both sideends.If extrapolating liner field to both non-linear zones asuming affine linearity,we are able to analize the spring charactristic only by elasticplastic analysis at both-ends without the necessity of considering geometric nonlinerlity . So we can analyze by easy procedure as compared with traditional integral formulation. This calculation results agree with experimental one in two kind sample springs.
