Material surface dynamic ice formation adhesion determination method and device thereof

Abstract

The invention discloses a material surface dynamic ice formation adhesion determination method and a device thereof, and aims to solve the problems that during ice formation adhesion strength determination, great difference exists between static ice formation method and the frozen structure and strength of an actual operating environment, while in dynamic ice formation method measurement, the acting surface of force is much smaller than an ice adhesion area, as ice is fragile in itself, is easily broken without pushing, and can be unmeasurable. The device includes a motor, a cantilever, a rotation speed determination apparatus, a rotation speed display and a high-speed camera, and connecting pieces are disposed at two ends of the cantilever respectively. The method and device provided by the invention ensure the integrity of dynamic icing during test, not only satisfies the simulation degree requirement for real icing, but also meets the requirements for strength protection of icing test pieces. At the same time, the measurement device provided by the invention has the characteristics of ingenious design, reasonable design, simple structure and easy maintenance. Practical tests show that the method and device provided by the invention can meet the dynamic ice formation adhesion determination requirement, the determination result is accurate, and the repeatability is good.

AI Technical Summary

Benefits of technology

This patented inventor describes an improved apparatus that measures static icing resistance while simulating actual conditions such as snow accumulation. These devices have various advantages over previous methods like electrical sensors and optical techniques. They allow precise measurements under different angles, making them ideal for studying these phenomena more accurately than previously possible. Additionally, they provide flexibility by allowing users to select specific parameters based upon their preferences, resulting in better results compared to other current technologies. Overall, it provides valuable benefits in research fields related to dynamic icings.

Problems solved by technology

The technical problem addressed during these studies relates to preventing frost buildup that occurs when there are condensation nuclei formed due to low temperatures near sea level (cold weather). This accumulation causes damage to various parts such as fans, gearboxes, etc., reducing their lifespan and effectiveness. To address this issue, antisking agents have been developed but they require large amounts of energy consumption. There has long existed a desire for more efficient ways to protect against ice deposition without requiring excessive resources.
