Geometrical and physical parameters of components of the absorber in the virtual prototype follow from those technical data of a specific passenger car. Bench tests are conducted and a series of experimental results have been obtained by the MTS absorber test machine for the damping force-velocity which can be imposed in the virtual prototype for dynamic simulation. The piecewise, the hysteretic looped and the abnormal looped hysteretic force-velocity curves for the absorbers are, respectively, input into the prototype.

减振器阻尼力—速度特性是根据MTS减振器特性试验机试验结果，通过分段拟合，分别以分段线性、迟滞环和迟滞环畸变情况输入虚拟样机进行仿真分析，试验及仿真结果比较说明：减振器速度外特性采用迟滞环非线性，比采用双线性化模型更接近试验结果，能够更合理地解释试验现象；减振器阻尼力速度特性曲线出现畸变，如在复原行程初期迟滞特性曲线出现交叉现象，可以引发减振器系统动力特性的高频振动成分增加。
