Mechanical impact dynamics is used to analyse the production and spread of stress wave when hydraulic pile hammer hammerblows piles, the stress wave influence the course of driving pile. slender hammer that is equal to wave resistance of the pile can bring ideal stress waveform. when the hammer weight is constant, efficiency of driving pile can be increased by means of selecting drive cap and cushion pad of different rigidity to match the hammer according to various geological condition and the pile. the structure and principium of hydraulic system of double - acting hydraulic pile hammer with double cylinders is studied in detail in the paper, the hydraulic system and electric control system of six - ton - double - actin hydraulic pile hammer with double cylinder is designed on the basis of it
本文應用沖擊機械繫統動力學分析打樁過程中錘體與樁撞擊時應力波的產生、傳播以及該波對沉樁過程的影響。認為與樁等波阻的細長狀錘體能夠產生理想的應力波波形;在樁錘重量一定的情況下,可針對不同的地質情況和樁,通過選擇不同剛度的樁帽和樁墊與其匹配來提高打樁效率。本文對雙缸雙作用液壓打樁錘液壓系統的結構和工作原理進行了深入的研究,並在此基礎上設計出六噸雙缸雙作用液壓打樁錘的液壓系統和電控系統。The planeness and integrality of the flier - plate were ensured effectively by exerting restrictive pressure, controlling heating and cooling rate, lowering welding temperature or reducing welding time as much as possible, etc. theoretical model of creating quasi - isentropic compression via 93w - ofc - tc4 - a1 - mb2 system flier - plate with graded wave impedance was established, and numerical simulation of the impact process was then carried out
