Description
このことから、減衰力制御によってΔIをΔI'減少させることができれば、感覚の増加分ΔEをk*(ΔI'/I)だけ減少させることができる。つまり、このように減少させることができる感覚の増加分ΔEが人間の感じる振動抑制感といった感度であり、物理刺激量Iを加速度z"とすると、ウェーバー・フェヒナーの法則を満たすΔEは
ΔE = k*(Δz"/ z"), (k:定数)となる。
而して、上記の演算により得られ、振動抑制感といった感覚の増加分を表す体感加速度増分ΔEに応じて減衰係数が補正される。
このとき、減衰係数Cが最小値Cminをとった場合には、運動方程式は次のようになる。
即ち、-mz1"min = Cmin(z1'- z0')+k(z1- z0) となる。
また、減衰係数Cが最大値Cmaxをとった場合には、運動方程式は次のようになる。
即ち、-mz1"max = Cmax(z1'- z0')+k(z1- z0) となる。
従って、ショックアブソーバABによる減衰力制御のΔz1"は次のようになる。
即ち、Δz1" = (Cmax- Cmin)(z1'- z0')/m となる。
よって、振動抑制感といった感度を表す体感加速度増分ΔE、即ちΔE = k*(Δz"/ z"), (k:定数)は次のようになる。
即ち、ΔE = k*[{(Cmax- Cmin)(z1'- z0')/m }/ z"], (k:定数)となる。
