Dynamic Modeling and Simulation for Heavy Mining Truck

The paper establishes whole model for 3550 heavy mining truck, andfounds digital prototype of whole truck by analysis to restrainttopological structure of whole truck model. Simulation result shows thatwhen truck is running at speed of 30km/h on C random road surface, it'sride comfort performance meets the demand of ISO2631 on 1/3 octavefrequency band separate evaluation rule.
