Abstract

In this study,
Random and Harmonic vibration test specifications for Automotive Lighting
systems are compared according to their damage content. Harmonic and Random
vibration specifications which have different durations and Acceleration Power
Spectrum Densities (PSD G) are plotted and compared according to damage
accumulated on one degree of freedom (SDOF) system. Outcome of this study is
the evaluation of fatigue strength of common or similar parts used on lighting
systems which are dedicated to different customers, different car segments; and
evaluation of the severity of new customer vibration durability test specifications
and evaluation of special design precautions for new design projects. Shorter
duration PSD G’s and Harmonic tests which have equivalent Fatigue Damage
Spectrums (FDS) can be created and instant design modifications can be tested
and evaluated. In addition, in this study, random test time reduction formula
was validated with physical tests.
