Study on Rational Distribution and Influencing Factors of the Axle Load for Multi-axle Vehicles

Axle shaft load is an essential parameters of the chassis design and vehicle dynamics analysis of a nineshaft all terrain crane.The axle load calculation model was adopted to get the axle load of a nine-shaft all terrain crane.The simulation based on the FEM analysis for a nine-shaft all terrain crane was made to verify the rationalization of the model and the calculation method.It can be used to get the axle load in consideration the axle distance,Spring stiffness and the convexity of road for nine-shaft all terrain crane.It also offers guidance for a nine shaft all terrain crane designing and assignment.
