Abstract |
This paper introduces the protection design method for electronic units of the self-propelled harvester, which is an agricultural machine used for field farming, among outdoor agricultural machines, and a reliability test evaluation method for it. The field farming work environment is an outdoor off-road surface that is generally divided into a ridge and a furrow. These off-road surfaces are mixed with various factors such as boulders, grass, and puddles, so shocks are constantly transmitted to the electrical equipment during movement and work, and dust is generated and moisture such as raindrops can penetrate into the interior of the electronic units the probability is very high. Typical external environmental factors that adversely affect the electronic units installed on the harvester body when the outdoor agricultural machine moves or works are impact, dust, and water. Therefore, this study proposes in detail a design technique that protects electronic units from the external environmental factors mentioned above and a reliability test evaluation method that can verify it. |
