An innovative method utilizing the phenomenon of mechanical resonance in machine drive systems of impact machines has been described. Energy accumulated in mechanical resonance is typically multiple times larger than the continuously supplied excitation energy. The amount of accumulated energy depends on the amplitude of vibration, mass and stiffness of system and present energy dissipation mechanisms. This form of energy can be extracted periodically each time after the amplitude of vibration reaches its maximum value. This effect could be implemented in drive systems of periodically operating machines, such as punching machines and presses. Significant reduction of energy demand in machines that use mechanical resonance in comparison with conventional machines was confirmed by means of simulations and experiments. Accumulation of the energy at mechanical resonance and its sequential extraction were presented together with a new prototype resonance punching press.

机械共振中的能量积累及其在冲击机驱动系统中的应用

已经描述了利用冲击机的机器驱动系统中的机械共振现象的创新方法。机械共振中积累的能量通常比连续提供的激发能大几倍。累积的能量取决于振动的幅度，系统的质量和刚度以及当前的能量耗散机制。每当振动幅度达到最大值后，就可以定期提取这种形式的能量。这种效果可以在诸如打孔机和压力机之类的周期性操作的机器的驱动系统中实现。通过模拟和实验证实，与传统机械相比，使用机械共振的机械中的能源需求显着减少。
