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。 相似文献

钢板弹簧虽然结构简单,使用可靠,但其质量大,行驶平顺性相对较差,所以本文提出新型钢板橡胶组合弹簧来提高汽车行驶平顺性、舒适性。本文基于APDL在ANSYS中对组合弹簧在装配过程中的接触非线性行为进行了分析,并分析了弹簧片几何参数对组合弹簧力学性能的影响。结果表明,相比钢板弹簧而言,七层8+8组合弹簧的接触应力降低了27.37%,七层8+16的组合弹簧的接触应力降低了47.8%;对比8+8组合弹簧、8+16组合弹簧和12+12组合弹簧可得,同时增加钢板层和橡胶层厚度,接触应力降低效果更加显著。由此可见,相同的位移荷载下,组合弹簧在装配过程中的接触应力比钢板弹簧的低,而且接触应力随着橡胶层厚度的增加而降低,同时增加钢板层和橡胶层的厚度更有助于接触应力的降低。 相似文献

钢板弹簧是悬架中力学性能比较复杂的构件,既是弹性元件,又是传递纵向、侧向地面作用力的传力元件,因此精确建立钢板弹簧模型是构造车辆多体模型的一大难点。根据钢板弹簧的结构和受载特点,考虑其工作过程中的大变形、片间摩擦迟滞性及非线性接触等因素,在ADAMS中精确建立了钢板弹簧的多柔体动力学模型。利用ADAMS软件对其进行动特性仿真,仿真分析的结果与试验数据对比,验证了模型是正确的。 相似文献

The taper leaf spring of tandem suspension of commercial vehicle is different from the traditional taper leaf spring. Thus, the professional software MSC.ADAMS/CHASSIS leaf spring, which is specially applied in traditional leaf spring, does not reliably develop the computational model of the taper leaf spring of tandem suspension. The multi-body dynamic model of the taper leaf spring of tandem suspension, which is developed in this paper, is a secondary development model that is based on the leaf spring model built by MSC.ADAMS/CHASSIS leaf spring. End contact and friction in the modified model are redefined to exhibit the hysteretic characteristics of the taper leaf spring of tandem suspension. The test of the taper leaf spring of tandem suspension is conducted to validate the reliability of the modified model. The tests in this paper are divided into two groups. The first group started at an unloaded state at an excitation frequency of 1/30 Hz and amplitude of 70 mm to acquire quasi-static behavior. The second group is conducted at various frequencies (2, 3 and 4 Hz) and various amplitudes (±1, ±3 and ±10 mm) in a loaded state to acquire dynamic behavior. A formula to calculate dynamic spring rate for leaf spring is proposed, and details about the formula are presented. The simulations are conducted under the same conditions as the test. The hysteretic characteristics and the relative error of dynamic spring rate from the test are compared with the ones from the simulations for the validation of the reliability of the modified model. 相似文献

The leaf spring is a representative type of laminated structure. Based on the linear theories of curve beams, the first derivatives of the leave??s status-vector of the leaf spring are provided. The first derivatives of the combination status-vector are obtained by properly dealing with the nonlinear interacted forces between adjacent leaves. Moreover, the precise integration technology and the transform matrix method are introduced to solve the equations. The force-displacement curve of a leaf spring is then calculated separately by using the present method and the finite element software ANSYS. From the results, the precision and advantages of the present methods for analyzing the leaf spring are revealed. The Coulomb??s damping ratio of the leaf spring is studied by using the present method. 相似文献
