这项工作的主题是振动冲击系统中冲击力行为的实验研究和数学建模，其中锤子安装在推车上，施加规定的位移。通过改变锤刚度和冲击间隙，可以研究不同激励频率下的冲击力行为。实验数据将用于验证数学模型。使用非线性分析更详细地研究了锤子的行为，该分析显示了锤子的各种响应，例如动态跳跃、分叉和混沌。
The subject of this work is the experimental investigation and the mathematical modeling of the impact force behavior in a vibro-impact system, where a hammer is mounted on a cart that imposes a prescribed displacement. By changing the hammer stiffness and the impact gap it is possible to investigate the impact force behavior under different excitation frequencies. The experimental data will be used to validate the mathematical model. The hammer behavior is studied in more detail using a nonlinear analysis, which shows the various responses of the hammer, such as dynamical jumps, bifurcations and chaos.
