基于AMESim的潜孔锤冲击作业过程的仿真

Simulation of DTH Hammer Impact Operation Process Based on AMESim

潜孔锤冲击器虽有厂家提供的规格参数,但针对不同地质岩层会表现出不同的工作特性。这对锤子的设计研究和实际操作都会造成一定的困惑。借助AMESim的系统仿真能力,构建出潜孔锤冲击器接近实际使用的仿真模型。通过对潜孔锤整机作业气动过程的仿真,得到锤头位移和腔体压力曲线,对潜孔锤冲击器的设计工作具有一定的辅助指导作用。

Though the DTH hammer impactor has the specifications and parameters provided by the manufacturer, it will show different working characteristics for different geological strata. This will cause some confusion to the hammer design research and practical operation. In this paper, with the help of AMESim′s system simulation ability, the simulation model of DTH hammer impactor is built, which is close to the actual use. Through simulation of the pneumatic process of the DTH hammer, the displacement of the hammer head and the pressure curve of the chamber are obtained, which can be used as an auxiliary guide for the design of DTH hammer impactor.
