Structural rod incorporating a vibration filtration mode

Structural rod intended to transmit tensile and/or compressive forces between two pins for fastening the rod to a structure or to an article of equipment, said rod having—bearings for fastening at each end, a first end and a second end along a longitudinal axis of said structural rod, wherein said structural rod has a primary rod that has an axial cavity, and a secondary rod inside said axial cavity so that said secondary rod is able to move in the axial cavity of said primary rod along the direction of the longitudinal axis, with said secondary rod being joined to said primary strut through at least one linkage element, and wherein:

• the primary rod has a bearing for fastening at its first end provided with a bore fitted to the dimensions of the fastening pin intended to be inserted in said bore, so that said primary rod is fastened by said bearing in a rigid manner along the direction of the longitudinal axis when said fastening pin is inserted in said bore, and;
• the secondary rod has a bearing for fastening at the second end provided with a bore fitted to the dimensions of the fastening pin intended to be inserted in said bore, so that said secondary rod is fastened by said bearing in a rigid manner along the direction of the longitudinal axis when said fastening pin is inserted in said bore, and;
• the primary rod has a fastening bearing at the second end provided with a bore whose dimensions are greater, at least along the direction of the axis of the rod, than the dimensions of the fastening pin intended to be inserted in said bore, so that said primary rod is linked by said bearing with a predetermined slackness along the direction of the longitudinal axis when said fastening pin is inserted in said bore, and/or;
• the secondary rod has a fastening bearing at the first end provided with a bore whose dimensions are greater, at least along the direction of the axis of the rod, than the dimensions of the fastening pin intended to be inserted in said bore, so that said primary rod is linked by said bearing with a predetermined slackness along the direction of the longitudinal axis when said fastening pin is inserted in said bore, and;
• the linkage element(s) are made of a deformable and elastic material.
