摘　　要：为了研究泵控液压起升机构二次起升时的动态特性,在全面考虑各种影响因素的基础上,采用功率键合图的方法,建立了系统动态数学模型,并对模型进行了求解,为泵控液压起重机起升机构的设计提供了理论依据。In order to study dynamic characteristics during subsequent lifting of a pump-controlled hydraulic hoist, a dynamic mathematical model of the system is established and solved with power bond graphic method on the basis of comprehensive consideration of various influencing factors. A theoretical basis for the design of pump-controlled hoist mechanism on hydraulic cranes is thus provided.
