摘要
在分析了新型开槽机原有液压系统存在的问题的基础上,指出了运用数字仿真法对其进行改进的必要性。采用新的建模方法———功率键合图法,建立了开槽机送料液压系统的动态数学模型,并用MATLAB软件对其进行了动态特性数字仿真研究。分析了各种技术参数对系统动态特性的影响规律,确立了改进后的送料液压系统。
On the basis of analyzing the deficiency of original hydraulic system of a new kind of slotting machine, the necessity of improving the hydraulic system was pointed out by means of numeral simulation. Aimed at feeding hydraulic system of the slotting ma- chine, a dynamic mathematical model was established by power bond graph, and numeral simulation on the dynamical properties of the system was investigated with the MATLAB software. Influence law of primary technology parameters of the feeding hydraulic system on dynamic characteristics of the system was expounded and improved feeding hydraulic system was accomplished.
