The specimen mounting fixture is pivotally movable relative to an axis perpendicular to the plane of the mounting face of the platform fixture and holds a specimen to be vibrated along its orthogonal axes. The mounting face of the platform fixture is provided with the necessary angle of incline relative to the plane of vibration, and the specimen mounting fixture is provided with mounting faces having the necessary angle of incline relative to the mounting faces of the platform fixture, such that turning of the specimen mounting fixture about its pivotal axis will expose the mounted specimen to vibration along each of its major orthogonal axes. A shaker platform is provided of a configuration having a mounting face of such angular incline to the plane of vibration so that the specimen to be vibrated may be attached directly to this face, and, in turning of the specimen along an axis perpendicular to said mounting face, subject the same to vibration along a number of other orthogonal axes.，下面是Multi axes vibration fixtures专利的具体信息内容。

权利要求

1. Multi axes vibration apparatus for a test specimen comprising: a shaker platform fixture movable to vibrate in a predetermined plane; said platform fixture having a mounting face disposed at a selected angle of incline relative to the plane of vibration; and mounting means on said platform mounting face, for pivotally mounting a specimen thereon, said means disposed orienting the orthogonals of a mounted specimen relative to the plane of vibration such as to select an angle of incline for the platform face thereto such that said specimen, without dismounting, can be pivotally turned through selected angular increments of 120* exposing successive sets of orthogonals to vibration.

2. The apparatus as in claim 1, wherein said mounting means comprises: a mounting fixture having mounting faces disposed to form the sIdes of an equilateral pyramid orthogonal at its apex; said pyramidal formulated fixture pivotally mounted on said platform face on an axis as from said apex perpendicular to the platform face; and said mounting fixture having a mounting face disposed in a plane perpendicular to the plane of vibration of the platform fixture, such that the base of said mounting fixture lying in the plane of the mounting face of the platform fixture selects an angle of incline therefor relative to the vibration plane such that, with a test specimen mounted on said mounting face of the mounting fixture with its major orthogonals parallel to the orthogonal legs of the mounting fixture, when said fixture is turned through angular increments of 120* about its axis, with the specimen so affixed, each of the major orthogonals of the specimen will be successively exposed to vibration.

3. The apparatus in claim 1 wherein, in combination with said mounting means: the selected angle of incline of the platform mounting face relative to the plane of vibration is equivalent to the angle at the base of an equilateral pyramid, having legs orthogonal at its apex, taken at the vertex of the intersection of two base lines, between one of the intersecting legs of the pyramid thereat and a line drawn from said vertex to the midpoint of the opposite base line.

4. The apparatus as in claim 3 wherein said mounting means comprises an axis mounting, perpendicular to said platform mounting face, with the specimen directly mounted thereon along one of its major orthogonals, such that said specimen, without dismounting, pivotally turned through selected angular increments of 120*, will expose successive sets of other orthogonals to vibration.

5. An apparatus as in claim 1, wherein said shaker platform fixture is substantially wedge-shaped in configuration with the face thereof comprising the platform mounting face.

6. An apparatus as in claim 5, wherein the angle of inclination of said platform fixture mounting face relative to the plane of vibration thereof is 35* 16'' .

7. An apparatus as in claim 1, wherein said platform fixture and mounting fixture comprise: the truncated components of a half cube cut from a cube by a vertical plane through one of its diagonals; said components of the half cube resultant from a plane passed coaxially through said former diagonal downwardly through the lower base vertex opposite said diagonal; said resultant upper component being a mounting fixture in the form of an equilateral pyramid orthogonal at its apex mounted on the lower component forming the platform fixture on the inclined angular mounting face thereof along an axis from the apex of said pyramid perpendicular to said platform face; and said mounting fixture having a mounting face perpendicular to a vertical plane of vibration such that a specimen mounted thereon with all of its major orthogonals parallel to the orthogonals of the legs forming the apex of said pyramid will, when turned on the axis of said mounting fixture through angular increments of 120*, expose all of said major orthogonals to vertical vibration.

8. An apparatus as in claim 5 wherein the angle of inclination of said wedge shaped fixture relative to a horizontal plane of vibration is equal to that angle, taken at the base vertex of an equilateral pyramid, orthogonal at its apex, subtended by a line from said vertex to the midpoint of the opposite base line and a line from said vertex forming one of the legs of said pyramid.
