The Research On Acceleration Switch Based On The Mercury Surface Tension Theoretic

In the aerospace, automotive, inertial navigation, rockets, vehicle inspection, torpedoes control of areas in which the emergence of various new technologies, all kinds of equipment are all moving in the direction of increasing miniaturization, in such a situation the request the use of the switch can achieve the requirements of miniaturization, but also to provide a reliable current and stability.Micro-fluid acceleration switch is the urgent need for the above reasons, the emergence of a new type of production, miniaturization in size in line with the stringent requirements in terms of performance, which can provide special state of steady acceleration run and can provide a more stable current characteristics of and to prevent spark generation, brought new development support for the gross national product and national defense science and technology.Based on the economic and social development, strong demand to try on the development of a new type switch based on the acceleration of the surface tension of mercury, proposed a new micro-acceleration switch design; Analyzed using mercury as the conductive medium superiority; In static context, I comprehensive the knowledge of fluid mechanics, elasticity, calculus related knowledge, Aiming at the determination of contact angle experiments are mostly derived from the macroeconomic situation,but for the micro-size, the experiment more difficult, the results are often imprecise. By theoretically authors calculated the size of the contact angle in case of mercury and silicon micro-channel media, and also calculate the precise location of mercury in the micro-channel surface. Have done a preliminary design of the overall size of the micro-switch. Provide for the micro-switches designed the theory of bedding and feasibility analysis.
