打桩锤

In order to analyze the influence of filled metal particles on impact force for hydraulic pile hammer, analytical solution of mathematic model for pile hammer filled with metal particles considering effects of metal particles was presented. In the solution, lumped mass were used as metal particles, a spring was used as contact stiffness between metal particles and hammer body, different variable lumped masses were used as pile hammer, the ram and anvil, a spring and a dashpot were used as the anvil cushion and pile respectively.
