应用离散梁原理在ADAMS中建立钢板弹簧的动力学模型。为适用于整车仿真,建立两片的钢板弹簧模型代替原有的多片模型。运用ADAMS中的试验设计模块ADAMS/Insight分析Beam梁参数,辨识影响刚度特性的主要参数,并以分析得到的参数作为设计变量,在ADAMS中进行优化,使其满足设计刚度。在满足刚度设计要求的前提下,对钢板弹簧的迟滞效应进行模拟。使用ANSYS建立钢板弹簧的有限元模型,模型考虑簧片间的摩擦,仿真得出了钢板弹簧在加载与卸载过程中的位移曲线,为钢板弹簧动力学模型的迟滞模拟提供了目标曲线。研究表明,经参数辨识后得到的钢板弹簧模型能准确反映其动力学性能,适用于整车仿真。
Application of discrete beam principle in ADAMS to establish the dynamic model of leaf spring. In order to be suitable for vehicle simulation, a two-piece leaf spring model is established to replace the original multi-piece model. The ADAMS / Insight analysis module was used to analyze the parameters of Beam beam. The main parameters affecting the stiffness characteristics were identified. The parameters obtained were used as design variables and optimized in ADAMS to meet the design stiffness. Under the premise of meeting the design requirements of stiffness, the hysteresis effect of leaf spring is simulated. The finite element model of leaf spring is established by ANSYS. The model takes the friction between leaf springs into consideration, and the displacement curve of leaf spring during loading and unloading is obtained by simulation. It provides the target curve for hysteretic simulation of leaf spring dynamics model. The research shows that the leaf spring model obtained after parameter identification can accurately reflect its dynamic performance and is suitable for vehicle simulation.
