Özet

© 2022, TUBITAK. All rights reserved.Automobile mirrors are exposed to vibration, as many types of equipment in the car, while driving. Vibrations on the mirrors may adversely affect driving by impairing the driver's clarity of vision or, depending on the frequency of vibration, may cause damage to the electronics inside the mirror and/or the outer casing of the mirror. Therefore, automobile mirrors should be designed considering the vibrations they will be exposed to, and vibration analysis should be performed by subjecting them to vibration tests after the design. Fixtures are needed for vibration tests, and an appropriate fixture design should be made to avoid resonance during these tests. The fixture's natural frequency to be designed must be greater than the natural frequency of the component to be tested. In this study, simulation studies are carried out for the side rearview mirror vibration fixture using Topology Optimization and Modal Analysis tools of Altair Inspire software, and fixture design is created according to these results. The final design of the fixture is produced, the simulation results are compared with the experimental results, and a 25% deviation is determined between the results. The transmissibility rate of the designed and produced fixture is maximum at 1250 Hz in the simulation environment and at 943 Hz experimentally.
