Description

Technical Field

[0001] The present invention relates to the field of vibration reduction technology, and in particular to a vibration reduction device and method based on the Léleau triangle. Background Art

[0002] Vibration damping devices are essential for improving the performance of precision instruments and mechanical equipment. They reduce the impact of vibration, ensure accurate operation of equipment, and improve system stability and safety. In the fields of ships, vehicles, precision processing and measuring equipment, vibration damping devices can effectively isolate low-frequency vibrations, reduce structural noise, and provide a more comfortable operating environment.

[0003] Traditional vibration damping devices play a vital role in many fields, but some of their defects limit their performance and application scope. First, traditional shock absorbers are mostly made of materials such as rubber, which have a limited service life and are not easy to replace, resulting in a significant decrease in vibration reduction effect over time. Secondly, these devices are often difficult to adapt to complex environments such as high and low temperatures, large load impacts, salt spray, and damp heat, which limits their application under extreme conditions. In addition, some traditional shock absorbers have complex structural designs, low space utilization, and large sizes, which not only increase manufacturing costs, but also make maintenance and replacement more difficult.

[0004] Stability and control issues are also common defects of traditional vibration reduction devices, especially in precision mechanical equipment, which may lead to a decline in equipment performance. At the same time, the design of complex structures also increases the risk of failure, especially in harsh environments, the reliability and durability of vibration reduction devices may be insufficient.

[0010] Further, the damping spring connecting device includes a damping spring, a card block, a locking plate, an inner card block slot, an outer card block slot and a connecting column; the card block cooperates with the inner card block slot and the outer card block slot on the locking plate through the upper sliding column, and cooperates with the slot on the connecting column through the lower sliding column; there are 5 inner card block slots evenly distributed on the locking plate, and an outer card block slot is arranged adjacent to each inner card block slot; there are 10 slots evenly distributed on the connecting column.
