Research on mechanism of anti-icing of polar ships based on ultrasonic vibration

Abstract

At present, the methods for ship anti-icing and de-icing are relatively outdated, mainly relying on traditional mechanical de-icing and chemical de-icing. However, these methods are not only inefficient but also may cause damage to the surface of the ship and increase maintenance costs. Based on the mechanism of ultrasonic vibration de-icing, this paper designs and develops the JUST electro-absorption ultrasonic vibrator, and conducts an in-depth discussion on its application in de-icing technology for steel materials of polar ships. By combining the numerical simulation method with the anti-icing and de-icing experiments, a systematic study was conducted on the anti-icing and de-icing effect of the frozen body of the hull steel plate of polar ships. The research covers the simulation and experimental comparative analysis of the electro-absorption ultrasonic vibrator under 11 different working conditions, revealing the influence of key parameters such as the arrangement mode, quantity, vibration frequency and vibration power of the ultrasonic vibrator on performance indicators such as the vibration displacement of the ship's ice cover and the ice cracking time.
