Executive Summary

Dampers in mechanical systems provide safety and comfort against dynamical and impact forces transmitted by external profiles. Since dampers are made of diverse elements, have a large range of performance variables. Therefore, analytical solution for predicting damper behavior is difficult. In the absence of analytical models, one of the popular and reliable methods is statistical modeling. In this study, a modeling approach for a continuously variable damper was successfully used with variable discrete time model through Euler's approximation. Effect of changing spring constants, forces, damper constants and initial displacement in a spring-mass-damper assembly for their effects upon damper characteristics were closely investigated via simulations using PROC MODEL. Initial values were specified in a VAR statement.
