Дослідження динамічних характеристик спеціалізованого транспортного засобу, що має дворівневу нелінійну систему підресорювання

Abstract

The work deals with the definition of an effective way of the suspension on the specialized vehicles and is aimed on improvement of the smoothness of its movement (riding comfort). A riding comfort is an important operational feature of the modern vehicles that allow to protect the passengers and goods from the influence of the vibrations during the vehicle movement. These are especially important for the transportation of the dangerous goods.The paper presents the design scheme of specialized vehicles, which has additional level of cushioning, with the nonlinear characteristic, which has a quasi-zero stiffness in the equilibrium position. The mathematical model of the dynamic behavior of the specialized vehicles are developed as a nonlinear discrete conservative system. The results of numeric calculations of the dynamic response of the vehicle on the impact is presented based on the developed model. A vertical vibrations of the luggage platform is analyzed caused by the kinematics impact that applied on the axis of the vehicle. The load is applied on the same time on each axis of the vehicle providing vertical vibrations of vehicle's structural elements. The obtained displacement over the time demonstrates the stationary polyharmonic behavior due to the conservativeness of the model and have been analyzed on its spectral composition. A comparative analysis of the frequencies and amplitudes of the oscillations have been carried out in the vehicle with linear and nonlinear arrangements. The obtained numeric data shows a significant reduction of the amplitudes of the vibrations and also frequencies of these vibrations that can be achieved using the nonlinear system of suspension with quasy-zero stiffness. A reduction of the amplitudes of the vibrational velocities has also been observed

Стаття присвячена вивченню ефективності застосування нелінійного дворівневого підресорювання спеціальних транспортних засобів, яке спрямоване на підвищення плавності їх ходу. Наведені результати теоретичних досліджень, щодо характеристик відповідного транспортного засобу, як нелінійної системи. Побудовано математичну нелінійну дискретну динамічну модель даного транспортного засобу, на основі якої проведено серію досліджень щодо вільних коливань транспортного засобу, як консервативної нелінійної системи. Наведено результати порівняльного аналізу щодо частот та амплітуд коливань які встановлюються в транспортному засобі в лінійній та запропонованій дворівневій нелінійній компоновках при імпульсному збудженні, що прикладається до коліс даного транспортного засобу
