Description

technical field [0001] The invention relates to a test device, in particular to a test device for testing the impact mechanical properties of a one-dimensional magnetic particle chain. Background technique [0002] Impact load is a common dynamic load, which may cause damage and fracture of the structure under its excitation, affect the stability of the mechanical structure, and cause harm to production and life. The development of impact-resistant cushioning systems has been a research hotspot in the field of structural dynamics. In recent years, as a typical energy-absorbing protection medium, the granular system has received more and more attention. It has the advantages of compact structure, convenient installation, and obvious energy-absorbing effect. The one-dimensional particle chain system is the simplest particle system, which attenuates the impact load through the interaction between particles, so as to achieve the purpose of buffering energy absorption, vibration...
