AI Technical Summary
Existing dampers in buildings, bridges, and railways are complex in structure and have unstable sealing performance, resulting in unstable resistance and poor sealing performance. Consequently, the dampers are bulky and cannot meet the high-efficiency vibration reduction requirements of modern equipment.
A hydraulic damping shock absorber was designed. A sleeve is fitted on the connecting column, and a bellows and a damping spring are installed between the sleeve and the support plate to form a sealed cavity filled with damping oil. The flow of the damping oil provides damping energy. At the same time, a cooling cavity is set between the sleeve and the inner cylinder and filled with coolant. Heat exchange is carried out through the flow of coolant to enhance the heat exchange effect.
It achieves stable damping energy dissipation through the cooperation of damping oil and coolant when the equipment vibrates, suppressing vibration, and improves the vibration reduction performance of the equipment through enhanced heat exchange, thus meeting the high-efficiency vibration reduction requirements of modern equipment.
