Abstract
This paper describes the use of a hybrid computer in the optimal design of impact absorbers. The objec tive is to minimize the maximum acceleration of the mass (load) being protected by the absorber during a transient, subject to the constraint of available "rattle space" within which the mass may move with out hitting the stops. The mathematical model of the absorber was implemented on the analog section of the computer, while the digital section performed parameter optimization and controlled the analog computer. The results are presented in the form of normalized curves showing the optimum stiffness and damping coefficients for various conditions and the resulting maximum acceleration levels in each case. The results show that hybrid computer optimization is fast and very effective for the optimal design of nonlinear impact absorbers.
