Abstract

Perfections in broadband accelerometers, characterized in that said accelerometers are constituted essentially by a sheet of constant section anchored in one of its end portions in a rigid support, comprising in its mass two cavities symmetrical with respect to the median plane of the sheet perpendicular to the plane of bending, said cavities passing from one part to the other and each having the shape of a cylinder whose generatrices are perpendicular to the plane of flexion of said sheet, said cavities not being reached in the center of said beam and being applied as such so that the thickness separating each of the tensile-compression faces of the sheet from the portion of the surface that limits the corresponding cavity closest to said faces is minimal, and by at least two thicknesses of stress glued on each of the portions of the traction-compression faces of the beam in front of the two cavities, and because it comprises in its free end portion a cavity identical to the first two cavities and having as plane of symmetry a plane perpendicular to the plane of flexion of said sheet and containing the axis of symmetry of said sheet.
