低频大振幅液压冲击器，以其优越的性能在非开挖施工方面拥有广阔的应用前景．对此类液压冲击器的建模和分析是十分必要的．据此，在某些基本假定的基础上，建立起液压冲击器的简化模型，直接用于数值计算和仿真，能得到与试验极其接近的结果
Low-frequency large-amplitude hydraulic impactor has a wide application prospect in non-excavation construction with its superior performance. It is necessary to model and analyze such hydraulic impactors. Based on this, based on some basic assumptions, a simplified model of a hydraulic impactor was established and used directly for numerical calculations and simulations, resulting in extremely close results with the test.
