In the work it is proposed a new discontinuous impact model based on the restitution coefficient and the finite duration of the collision, which are functions of the velocity before the collision. The model was validated during modelling, experimental and simulation studies of the bifurcation dynamics of an oscillator of one-degree-of-freedom with a one-sided limiter. The simulation results using the new discontinuous impact model were compared with numerical solutions obtained with the use of the continuous five-parameter Hunt-Crossley model assuming the obstacle compliance. It was shown that the new discontinuous model produces results that are as realistic and consistent with the experimental data as the compliant impact model. Moreover, the significance of the dependence of the restitution coefficient on the speed before the collision and the contact time during the collision in obtaining a good agreement of the simulation results with the experimental data were shown.

在这项工作中，提出了一种新的基于恢复系数和有限碰撞持续时间的不连续碰撞模型，它们是碰撞前速度的函数。该模型在具有一侧限制器的单自由度振荡器的分岔动力学的建模、实验和仿真研究中得到验证。将使用新的不连续冲击模型的模拟结果与使用连续五参数 Hunt-Crossley 模型（假设障碍物顺应性）获得的数值解进行比较。结果表明，新的不连续模型产生的结果与合规影响模型一样真实且与实验数据一致。而且，
