Abstract

"DISPOSITIVO MECáNICO COMPREENDENDO UM ELEMENTO DE ESTRUTURA ALONGADO DESTINADO A AMORTECER PELO MENOS PARCIALMENTE ALGUNS CHOQUES POR DEFORMAçãO". A invenção se refere a um dispositivo mecânico, compreendendo um elemento de estrutura alongada, destinado a amortecer pelo menos parcialmente alguns choques por deformação. Este elemento de estrutura ou peça compreende um perfil de seção reta escolhido, este perfil sendo munido de alterações localizadas (<244>2, <244>3, <244>4) de formas e posições respectivas, escolhidas para satisfazer sensivelmente uma lei dada de deformação sob esforço conjunto de compressão no eixo da peça, e de torque de eixo perpendicular a um plano que passa por este eixo. Esta lei comporta uma fase de absorção de energia, seguida de um desaparecimento da peça.
