Vibration Formulae on the Foundation of Hammer-Forging Machine

抄録

For convenience'sake of designing the foundation and mounting of Hammer-Forging Machine, the author has introduced the vibration formulae based on impact force, in case its shape is rectangular and saw teeth. These formulae would solve the problem more accurately for actual phenomena than usual formulae which are introduced by the percussion theory on semi-rigid body. By strict consideration of physical meaning, some of these formulae are solved by conventional treatment and contain some approximate solution. But the author has found that the result of the foundation and mounting practically designed for the 1/2 ton steam hammer and 1 ton one by these formulae and the various data, reported, are more similar to actual phenomena. These formulae are considered convenient for service and also valuable for practical design.
