Materials Substitution for Scientific Use of Mg Castings on Motorbikes

摘要

To promote a technological use of Mg alloy castings on motorbike, a technical routine for material substitution was demonstratively presented with engine crankshaft case and motorbike wheels. It was shown that, subjected to failure analysis, comparative FEM analyses, structural redesign, numerical optimization of casting process and strict tests of prototypes, the service performance of the Mg castings can be ensured, in addition to the performance improvement stemming from the advantageous properties of Mg alloys.
