Tokyo Metropolitan University Development Of Bolt / Nut Vibration Simulation Technology


In a word, Tokyo Metropolitan University's research team recently developed a simulation technique that can predict the vibration speed of a hammer with a bolt when it strikes a bolt / nut. The technology is expected to shorten the construction of multi-material buildings, contribute to the maintenance of civil construction management.


The program for this simulation technique is to first enter the shape model, the spring constant, the Paassoid ratio, the surface roughness, the bolt axial force, and then calculate their values in C ++ and predict the number of vibrations (in Hertz). So you do not need to rely on rigidity and other data, as long as the appropriate number of shocks can predict the appropriate fastening force.
