Otomobil güç aktarım sistemleri için elastomer yaylı sönüm sisteminin tasarımı ve doğrulanması

Abstract

 Automobile powertrain system dynamics  Elastomer clutch damper spring validation  Elastomer spring durability under dynamic forces In this study, the comparison has been performed with the traditional metallic helical springs, and the advantages and disadvantages of the systems with elastomer springs and metallic springs were revealed with analysis and test results. The flowchart of the study can be seen below; Figure A. Elastomer damper spring validation methodology performed in the study Purpose: The main objective is to observe the performance of new generation elastomer damper in an automobile powertrain system based on experimental approach comparatively with conventional metallic damper systems. Theory and Methods: Experimental bench tests have been performed to reveal the behavior of the elastomer damper clutch in the powertrain system of the automobiles. Results: Due to the hyperelastic and viscoelastic properties, the elastomer materials react unlike to metal materials depending on many variables such as strength, time, temperature and material properties. Numerical results are indicated in the manuscript. Conclusion: Results of the study show that due to hyperelastic and viscoelastic properties of rubbers, the stiffness characteristic of rubber spring tends to loose within the time which may cause insufficient vibration damping. Also, this study provides and presents new testing and optimization approaches on the clutch disc using rubber damper springs.
