AI Technical Summary
Existing magnetorheological vibration dampers suffer from problems such as difficulty in integration, insufficient load-bearing capacity and resistance to lateral forces, and inadequate heat dissipation. Furthermore, it is difficult to effectively combine active and semi-active components.
A hollow magnetorheological vibration damper is designed, which adopts an inner cylinder, an outer cylinder and a piston assembly structure. Combined with the intermediate cylinder and piston core, it realizes the integration of active control and semi-active control. The hollow structure increases the heat dissipation area and improves the load-bearing and lateral force resistance capabilities.
It achieves the integration of active and semi-active control, reduces energy consumption, improves the heat dissipation performance and load-bearing capacity of the vibration damper, and reduces abnormal noise faults.
