Abstract
Taking the suspension system of the truck cab as the research object, aiming at the three working conditions commonly used by engineering vehicles, cab suspension system dynamics model is established in ADAMS/view. The stiffness and damping of the front and rear suspension are design variables, and the maximum acceleration of the cab floor is minimized as the design objective. ADAMS’s own optimization module is used to optimize the suspension parameters, and the optimal matching value of the suspension parameters under the three working conditions is obtained. And On this basis, the three sets of values were optimized by DOE orthogonal test technology, and a set of optimal matching values of suspension parameters suitable for three kinds of road conditions was obtained. Finally, the accuracy of the model and the optimization value of cab suspension parameters are verified by the actual road test results.
