Abstract

See full text

A vibration test jig may include an upper jig frame to which a vibration test object is fixed and a lower base frame mounted to an oscillator, and a plurality of double parallelograms connected between the jig frame and the base frame, for generating displacements in an upward/downward direction and/or a forward/rearward direction. Each of the double parallelograms may include a complex four-articulation link structure and a wire rope isolator. The vibration test jig can simulate a deformation mode due to generation of resonances.
