Abstract:In this paper, the deformation survey method on the Oresund Bridge is stated in details. In first part of this report, some general information about this striking project is given. The survey methodologies and calculation process as well as a comparison of survey results carried out by two construction teams are also involved in this report. Then, three methods that are usually used in deformation surveys will be explicit, and a discussion about the most suitable one that can apply to the project in reality is followed. | |||

Abstract:The reconnection launcher, which launches solid projectile, is a kind of the electromagnetic launchers. The operation principle of the reconnection launcher is introduced. A model of three-stage reconnection launcher is set up by MATLAB and the velocity of the projectile is simulated. As the velocity of the projectile is a variant during the launch, a velocity measurement method for the three-stage reconnection launcher in practice is presented, on the basis of computer and micro controller unit (MCU). A practical three-stage reconnection launcher is fabricated and a 160g-plate projectile is launched. The final launched velocity is accelerated to 24.991m/s in three steps. A velocity curve is gained by this method and it is consistent with the simulated result. | |||
