Software beefs up tractor radiator-guard mount

摘要

Caterpillar's Track-type Tractor Div. (Peoria, IL) just boosted the strength and fatigue resistance of a radiator-guard mounting system on its D8 Track-type tractor. To save steps, the design team used technologies that reduce drawing time and eliminate costly metal tooling. Using 3D CAD, rapid prototyping, and investment casting, engineers brought the prototype to market in one-fourth the typical time.
