		<abstract>Neste trabalho apresentamos os primeiros resultados do estudo do isolamento vertical em um sistema de pêndulos multi-aninhados, para aplicação como isoladores vibracionais passivos dos espelhos da próxima geração de detectores interferométricos de ondas gravitacionais, como o LIGO Voyager. As funções de transferência teórica dos modos verticais indicam um fator de isolamento de até seis ordens de grandeza em 10 Hz. As medições dessas oscilações apresentam frequências de ressonância indesejáveis e indicam que o sistema necessita de melhorias. Aqui propomos algumas soluções para isso, que já estão sendo estudadas. ABSTRACT: In this work, we present the first results of a study of a vertical isolation of the multi-nested pendula, to be applied as passive isolation on the mirrors of the next generation of interferometric gravitational-wave detectors, such as LIGO Voyager. The vertical transfer functions indicate an attenuation factor of up to six orders of magnitude at 10 Hz. The measurement of these oscillations shows undesirable resonance frequencies and indicates that the system needs improvement. Then, we propose some solutions to this problem, which are already being studied.</abstract>
