SUBSTANTIATION OF DYNAMIC PARAMETERS OF VIBROPROTECTION OF PNEUMATIC JACKHAMMERS WITH A SEPARATE BARREL
As a result of mathematical modeling of the system “standard test bench - pneumatic jackhammer with a separate barrel”, rational values of the stiffness coefficients of the shock-absorbing spring and ring rope vibration isolators of hammer are determined, at which the minimum root mean square values of vibration velocity and vibration acceleration of handle are provided. A comparison of vibration characteristics of the MO-2B hammers and with a separate barrel was made, the advantages of a hammer with a separate barrel were revealed.
