Description
R=δF/δs
[式中、Fは力であり、そしてsはたわみ(deflection)である]
を用いた力/たわみ直線の傾きで決まる。その上、スプリング構成要素の場合、許容ばね限界応力(spring limit stress)が特徴的な特徴であり、これは、DIN 2088およびDIN 2089に従い、引張り強度Rmに定数を掛けることで計算される。前記定数はスプリングの幾何学的形状および用途に応じて0.4から0.7であるが、これは個々の環境に依存する。
(C%)/(N%)=0.8から2.0
[(Nb%)+(V%)]/10(Ti%)=5から17。
ε=100・Δd/d0
を用いて断面積の差Δd=d0−dから相対的寸法変化εとして計算した。
