Calculation of optimal parameters of the foundation for woodworking machines with large dynamic loads

The groundwork for machines with dynamic loads should meet the calculation requirements regarding strength and suitability regular operation need occupational safety standards acceptable vibration levels. In addition, fluctuations in not cause a harmful impact on technological processes, equipment, devices located foundation or outside it.A mathematical model of vibrations methodology calculating parameters are presented, taking into account from unbalanced masses characteristics ground base.The is solution to differential equation vibrations.The article refutes number conventional concepts body foundation, its base, geometric center damper between ground.The basis determining damping modulus logarithmic decrement damping.It constant depends elastic properties soil, as well installation mass. more significant decrement, faster extinction occurs. It was found that an increase resistance coefficient allows reducing mass simultaneous area so acts limitation.It established ensure prevent resonance ratio frequency natural forced be at least 1.5.The optimal mass, base depth laying carried out according criterion minimum cost construction.An application software has been developed calculation. projection machine large two-story sawmill.
