Evaluation of mechnical preoperties of vibration damping steel sheets and their application to automobile engine oil pan
초록
In recent years reduction in noise and vibration in automobile has been strongly required not only from the standpoint of environmental regulations but also for raising the commercial value and ride comfort. Vibration damping steel sheets, which are composites made by sandwitching a visco-elastic resin layer between two steel sheets, have been developed as effective noise-abating materials and have found a growth of use in automobile industries. Vibration damping steel sheets for commercial use must be excellent in vibration damping property, press formability and spot weldability, but are inferior to ordinary steel sheets. In this study, the mechanical properties of vibration damping steel are evaluated, and press formability is analysed on the basis of those properties and shear bonding strength. The development of engine oil pan using damping steel sheets are also reported, focusing on serious problems in oil pan drawing.
