Estudo do movimento de balanço de um sistema com perturbação interna
The roll motion of a system with internal perturbation is investigated. The system consists of a rigid box with a pendulum fixed on the top and supported by an elastic dissipative suspension. The mathematical model is obtained by the Newtonian Mechanics. One establishes the rtability chart with …

Reações de impulso em mecanismo articulado plano com folga nas articulações
The dynamic performance of a four-bar plane linkage with clearance in one of the revolutes is investigated. Impulsive reactians at the joints were evaluated during impact and free flight modes. External and inertia loads are accounted for. The analysis was applied to a similar linkage witha out …

Mejoramiento de un sistema mecanico por control activo
In this work the suspension of an automobile car is investigated for the possibility of improving its dynamics by the addition of an active element. The system is simulated by idealized masses, springs and dashpots. The proposed active compQ nent is visualized as a servo mechanism ora force …

Aplicação do método de Ritz extendido na análise de vibrações e estabilidade dinâmica de placas circulares
The aim of this paper is to present an appraximate soluction for the natural frequencies of circular plates, under axisynnetric transverse vibration. It was used the Ritz method to form a minimizing sequence for the energy functional. Initially a review of the basic principles of the variational …
