Applying 3D-CAD to turbocharger development

Ishkawajima-Harima Heavy Industries has developed a 3D-CAD system for turbochargers, satisfying requirements for digital mockup development.

Traditionally component clearances and interferences, and assembly feasibility, have been verified using real models. Now, three-dimensional computer-aided design (3D-CAD) can develop a digital mockup (DMU) in virtual space, reducing development time for new products.

A 3D-CAD approach works particularly well with original equipment manufacturer (OEM) suppliers, who do not require a large-scale computer system to handle the design of an entire vehicle. However, suppliers often must have multiple CAD systems to handle the full range of OEM requirements. Supplementary systems also are needed to manage data between the systems. Turbocharger manufacturer Ishikawajima-Harima Heavy Industries (IHI) recently has begun using 3D-CAD for engineering design and development.
