| Abstract |
The problem of optimal shock isolation is discussed for objects
modeled by a system of two bodies connected by a linear viscoelastic
element. We state the general optimization problem and two important
particular cases-the problem of limiting capabilities of shock
isolation and the problem of parametric synthesis of shock isolators.
Optimal parameters are determined for passive isolators consisting
of a spring and a viscous-friction or dry-friction damper. Minimized
is the peak displacement of the body connected to the base subject
to shock disturbance, provided that the force of interaction between
the components of the object does not exceed a prescribed maximum
admissible value. For each type of the isolator,
the optimal value of the performance index
to be minimized is compared with the absolute minimum
that results from the limiting performance analysis of
isolation of the shock disturbance of a given type.
A relation of the problems considered in the present paper
to the problem of optimization of equipment for the
prevention of impact-induced injuries on transport, in industries,
construction work, and sports is discussed. |
