... support itself tends to increase the resonance frequency of the pipe string as well as the resonance amplitude of buffer, while reducing the maximum axial stress of the pipe in case of the small spring constant. The hard-spring support strengthens this tendency and the soft-spring support tends to act...

... the resonance amplitude of the vibration of the pipe string if their volume and mass were kept constant. A buffer which satisfied the above condition was found to be the cylindrical one with larger disks. This kind of buffer reduced the resonance amplitude of the vibration by about two fifth as compared...

... on the vibration was analyzed theoretically. The results indicate that the above mentioned absorber attached to the buffer could almost reduce the resonance amplitudes of the buffer and pump modules to almost 50% values and the maximum axial stress produced at the top of the pipe string to about 83% value...

... was analyzed theoretically. The results indicate that the abovementioned absorber attached to the buffer could almost reduce the resonance amplitudes of the buffer and pump module to almost 40% values and that larger mass of the absorber more reduces those amplitudes within the range where the mass ratio...
