Hitachi Construction Truck Manufacturing sought to improve payload efficiency and fuel economy by reducing dump truck weight while maintaining durability and fatigue life. Engineers used integrated simulation workflows to evaluate vehicle dynamics, structural loads, thermal behavior, and rollover protection. Multibody simulations helped determine real-world load cases, while topology optimization guided component redesign. Using Altair’s unified licensing model, Hitachi accessed multiple analysis tools within a single environment. The result was a 10% weight reduction in major structures, faster development cycles, improved fuel efficiency, and increased confidence in truck reliability under demanding mining conditions.
