AI Technical Summary

Problems solved by technology

As a shock-absorbing energy-dissipating component, the ability of the shape memory alloy damper to absorb and dissipate energy is limited by the displacement and speed of both ends of the device, and the energy dissipation capacity is often insufficient.
