Tokyo metropolitan university research team has developed a set of simulation technology, can use a computer to predict hammer percussion speed vibration of bolt/nut.The technology can shorten the material more complex project, contributing to the maintenance management of civil engineering and construction.The application of this simulation technique is first input shape model and elastic coefficient, he ratio, surface roughness, bolt axial force, and then calculated by c + + and their numerical prediction and earthquake (unit: Hertz).So you don't need to rely on the rigid data and so on, as long as cooperate with the proper vibration frequency will be able to predict the proper fastening strength
