Point masses:	\({m}_{{P}_{1}}={m}_{{P}_{2}}={m}_{{P}_{3}}=\dots \dots ={m}_{{P}_{8}}=m\)
Link stiffness:	\({k}_{\mathrm{AP1}}={k}_{\mathrm{P1P2}}={k}_{\mathrm{P2P3}}=\dots \dots ={k}_{\mathrm{P8B}}=k\)
Viscous damping:	\({c}_{\mathrm{AP1}}={c}_{\mathrm{P1P2}}={c}_{\mathrm{P2P3}}=\dots \dots ={c}_{\mathrm{P8B}}=c\)

Linear elastic translation spring	\(k={10}^{5}N/m\)
Point mass	\(m=10\mathrm{kg}\)
Unidirectional viscous damping	\(c=50N/(m/s)\)

Point \(A\) and \(B\): built-in (\(u=0\))

Acceleration spectrum at supports \(\ddot{u}(f,a)\) standardized to \(1.m{s}^{-2}\)

Points \(A\) and \(B\): \(\ddot{u}=\ddot{u}(f,a)\)
