IMPACT SYSTEM RESTITUTION COEFFICIENT DEPENDENCE ON GEOMETRY

摘要

One of the important parameter of impact process is the coefficient of restitution. Practically important task is to determine the coefficient of restitution in a contact tasks, when is necessary to avoid repeated transient processes during the contact. Many researches accept the coefficient of restitution a constant (Viba, 1988) (Plavnieks, 1969). Contrary in present report this coefficient is obtaining during calculations. Our aim is to obtain an effect equal to plastic impact, when not repeated impacts will happened in system. Prepared calculations shown detailed wave interaction picture in construction. Comprehensive parametric analysis was realized. Results of elastic and viscoelastic material behaviour were compared.
