抄録

In the first report the foundamental equation about characteristics of the tup motion was replaced with the algebraic simultaneous equations of higher order applying successive approximation of integral, and their approximate solution was obtained. Now in this case several numerical calculations for a 500 kg air hammer of Beche type are attempted through the solution as follows. Characteristics of the tup motion are to be influenced by the speed of crank shaft driving the pump piston and the most adaptive or the principal speed which means that one cycle of single blow accords with one cycle of pump piston, is to be found. Moreover the torque of crank shaft, the air pressure and temperature in both cylinders are calculated. And then referring to the desertation of experimental research "Untersuchung eines Schmiede-lufthammers" the writer has found that characteristic curves obtained by our analysis are similar to these experimental records researched through the reliable installations with pickup, indicator and recorder.
