Problems solved by technology

[0007] However, when a fixing jig according to the related art is used, individual product test results and actual vehicle test results are different
Therefore, there are limitations in simulating the relative displacements, such as torsion or bending, introduced by the fixing fixture into the actual panoramic sunroof

Abstract

A vibration test fixture may include: an upper fixture frame to which a vibration test object is fixed and a lower base frame mounted to a vibrator; and a plurality of double parallelogram members, the Dual parallelogram members are connected between the clamp frame and the base frame for displacement in upward / downward directions and / or forward / backward directions. Each of the dual parallelogram members may include a compound four-joint linkage structure and a wire rope isolator. The vibration test fixture can simulate deformation modes due to generation of resonance.

Description

technical field [0001] The present disclosure relates to a vibration test fixture, and more particularly to a vibration test fixture for simulating the relative displacement of, for example, torsion or bending of a vehicle component, including a panoramic sunroof, in a vibrating environment. Background technique [0002] Generally, repetitive vibrations transmitted from a road surface or driving components of the vehicle such as an engine during running of the vehicle are transmitted to the vehicle body, and components such as the vehicle body or the sunroof are deformed due to the repeated transmission of the vibrations. [0003] Since deformation causes cavities or steps which in turn cause water leakage or deterioration in appearance, a quality assurance process is performed by measuring relative displacement such as torsion or bending by vibration testing before actual design of the vehicle. [0004] For example, a model analysis test is performed by providing vibration ...
