【摘要】 液压桩锤是一种建筑用沉桩设备,该文介绍一种频率可调的液压桩锤,以适应不同沉桩工况,在阐述其结构和工作原理基础上,建立了低频大位移工况的数学模型,为以后设计此种类型的液压桩锤提供了理论基础。更多还原

【Abstract】 A hydraulic hammer with adjustable frequency which can be used in different peg-sinking conditions is introduced in this paper. Based on the descriptions of the work principle of its structure, the mathematics model of the working condition with low frequency and large displacement is built.更多还原
