Abstract


Articulated dump truck (ADT) is a non- highway truck transport vehicles , much the attention of the world due to the the extensive road adaptability and good maneuverability . With the rapid development of China's national economy , the government has increased investment in infrastructure , ADT will become an indispensable means of delivery by the road construction, railway construction , mining and other types of engineering , with good market prospects . The suspension system is a general term for force transmission between the car frame and axle ( or wheel ) , connected devices . Its role is the impact force generated by the uneven pavement slow aggregate transmission effect in the twisting force and the force between the wheels and the frame , the attenuation of vibration, to ensure that the automobile ride traveling . Suspension of the car ride comfort , handling stability and ride comfort , and a variety of performance has a significant impact , which objectively suspension design more stringent requirements to ensure that the suspension with good elastic kinematic characteristics and frequency characteristics of the critical parts have sufficient strength and longevity . In this thesis an articulated dump truck , the CAE software UG create a three-dimensional model of the chassis . The completion of the I-DEAS software before the suspension longitudinal force transmission mechanism , the three-dimensional digital model of the U - shaped frame and finite element model . Static and vibration modal analysis using finite element theory on three U -shaped frame , stress distribution , natural vibration characteristics data . Fatigue life analysis in accordance with the design requirements of modern suspension , before, during and after the U -shaped frame . By the analysis results , before, during and after the U -shaped frame overall life of the more reasonable distribution of the U - shaped frame to meet overall performance requirements .
