摘　　要：随着海洋工程发展,深水作业对设备提出了更高的挑战。为实现水下打桩,打桩锤配套的砧铁底端面需进行排水槽设计改造。通过两种改造方案分析,综合加工工艺、受力面积及接触面压强等因素对比,选择采用3°倾角锥型槽方案。对改造后的砧铁在不同工况下进行了有限元分析,验证了方案设计的合理性,为改造方案的优化和选择提供依据。With the development of offshore engineering,deep-water operation poses a higher challenge to equipment.In order to realize underwater piling,the bottom end of anvil matched with pile hammer needs to be reformed by drainage trough design.Based on the analysis of two modification schemes and the comparison of processing technology,stress area and contact surface pressure,a 3 degree inclined conical groove was selected.The finite element analysis of the improved anvil under different working conditions verifies the rationality of the scheme design,and provides the basis for the optimization and selection of the transformation scheme.
