Calculation of the Modulus of Elasticity with Using Natural Frequency Formula and Updated Finite Element Analysis Of Automotive Rear Lamp Lens
Öz: In this study; the weight of the modal accelerometer used in the RovingHammer Impact Test Method was added in the finite element analysis (FEA) andthe undamped modal analysis of the automotive rear lamp lenses were performed.Also, calculated new Elastic Modulus for Polymethylmethacrylate (PMMA)material with using natural frequency formula and this value was used in theANSYS WB® program and the undamped modal analysis was repeated. Afterthat, frequency response functions (FRFs) of an automotive rear lamp lens wereobtained by using Roving Hammer Impact Test Method. At the same time;dynamic characteristics of the structure, natural frequencies, damping ratios andmode shapes were obtained. Damping ratios were calculated from the FRF’s byusing the Half Power Method. Finally, experimental modal analysis (EMA) andFEA results were compared.
