【 摘 要 】

One of the most efficient ways of improving percussion-action machines is selecting the shape of an anvil block such that to generate impact adequate to penetration resistance of rocks. From this viewpoint, the authors present a numerical-analysis algorithm and implementation to determine and analyze impacts generated by a complex-geometry anvil blocks. Application of the automated calculation is illustrated in terms of impacts generated in down-the-hole hammers.
