This paper describes an innovative analytic/numerical method for modeling steering systems for automotive applications. Starting from a detailed literature analysis and pushed by vehicle manufacturers’ needs, a simplified steering dynamic model, characterized by few parameters, has been identified. It guarantees both the replication of the dynamic behavior of real systems, generally represented through more complex multibody models, and the reduction of the simulation time of the entire vehicle system, making it suitable for dedicated numerical computing environments, such as the, so-called, explicit multibody codes. Moreover, particular emphasis has been place on the correct evaluation of the influence of friction on steering system dynamics.

本文介绍了一种创新的解析/数值方法，用于对汽车应用的转向系统进行建模。从详细的文献分析开始，并在汽车制造商的需求推动下，已经确定了一种简化的转向动力学模型，其参数很少。它既保证了通常以更复杂的多体模型表示的真实系统动态行为的复制，又保证了整个车辆系统仿真时间的减少，从而使其适合于专用的数值计算环境，例如所谓的，明确的多体代码。此外，特别强调了对摩擦对转向系统动力学的影响的正确评估。
