FIELD: testing equipment engineering, namely, engineering of stands for vibration testing of primarily long-length large-dimensional optical devices.
SUBSTANCE: stand contains vibro-exciter with platform and device for holding product being tested, made in form of hollow rectangular prism and mounted on the platform. Prism is made eight-sided and has U-shaped rigidity elements, lower and end edges of which are held appropriately, on internal surfaces of side and end sides of prism. Also, in edge sides of prism apertures are made for letting through them elements for holding product being tested. Stand may be provided with detachable hollow conic element with end surfaces for interaction with platform and fastening to it of one of end sides of prism. Also, stand may be provided with cylindrical guides, held on end sides of prism.
EFFECT: improved operation characteristics, possible transfer of vibration to product being tested in axial direction, simplification of preparatory operations for transverse transfer of oscillations.
