Description

Method for Manufacturing a Damper Having Excellent Vibration-prevention Properties This embodiment relates to a method for manufacturing a damper having excellent vibration damping characteristics. The content described in this section merely provides background information regarding the present embodiment and does not constitute prior art. The Paris Agreement, which regulates greenhouse gas emissions more strictly than the Kyoto Protocol of 1997, entered into force in 2015. Led by the EU, the world agreed to limit the rise in global average temperature to no more than 1.5°C by 2100, and more than 120 participating countries, including China, Europe, the United States, and Japan, are aiming for carbon neutrality by 2050. Accordingly, Korea has also set a target of achieving carbon neutrality by 2050 through the expansion of renewable energy, including solar power generation, by setting the share of renewable energy generation at 45.3% by 2036 in accordance with the '10th Basic Plan for Electricity Supply and Demand' and the '5th Basic Plan for New and Renewable Energy' announced in 2020. With the increase in solar power generation facilities and the growing interest in the maintenance of existing facilities due to domestic and international renewable energy supply policies, there is growing interest in the development of advanced technologies for stable energy supply facilities and equipment for solar power generation facilities that have been in operation for over 20 years. It is reported that the initial target energy production capacity of solar power generation systems gradually decreases over time. A significant reason for this decrease is losses and failures caused by vibrations of the panels within the system. According to a NASA report, vibration control has been confirmed to result in an approximately 20% improvement in the energy supply of solar panels. Furthermore, there are research reports regarding the causes of battery cell failure involving continuously applied vibrations, and analyses of the increasing cracking in panels during vehicle movement report crack formation due to vibration-induced fatigue. As the operating time of battery cells increases, cracks potentially enlarge, adversely affecting the panel's function and performance, and causing spotting that leads to a decrease in panel output. Accordingly, there is a demand for dampers with improved vibration prevention characteristics.
