Development of High-Pressure Die-Casting Simulation and Verification in Motorcycle Parts

摘要

With the growing demand of weight reduction in recent years, hollow structural casting products, which are weldable, of high strength and rigidity, are produced by high-pressure die-casting. In order to develop such a cast product in a short period of time, techniques are required to predict the castability, weldability, strength, quality at an early stage of development. The conventional simulations, however, are unable to satisfy the aforementioned demands. In an attempt to respond to those demands, the authors through this reported research quantifiably analyzed the porosity in the casting, and realized predicting of actual strength and elongation. By applying the newly developed casting simulation to the motorcycle parts, the cast part design can be accurately verified, allowing signification reduction of the thickness and weight.
