摘要

摘要: 装载机液压缸输出功率是分析液压系统能量分配规律、计算液压系统效率、评价液压系统元件匹配是否合理的重要参数之一。本文以动臂缸为例,研究了其输出功率变化特性的测定方法。在分析建立动臂缸输出功率数学模型基础上,选用了动臂缸工作参数测试用传感器与数据采集仪,并实机测试了装载机铲装小石方时动臂缸无杆腔、有杆腔油压及活塞位移,应用Vib'SYS和nSoft软件对实测油压和位移数据进行了分析处理,制取了单次典型作业循环动臂缸无杆腔与有杆腔油压及活塞位移变化历程;应用MATLAB对制取的单次典型作业循环不同作业段的动臂缸油压和位移进行了拟合,通过编程处理获得了动臂缸不同作业段的功率波形,将各作业段功率波形按作业时间顺序进行了合并,获取了铲装小石方时动臂缸输出功率变化特性曲线,分析结果表明,文中提出的动臂缸输出功率测定方法是可行的。

Abstract: The output power of loader hydraulic cylinder was one of important parameters to analyze the energy distri-bution rule, calculate the efficiency of hydraulic system and evaluate the matching reasonability of hydraulic compo-nents. In this paper, the determination method of the output power change characteristic of loader lifting arm cylinder was studied. Based on the analysis and establishment of the output power mathematical models of lifting arm cylinder, the sensors and data acquisition instrument for testing the working parameters of lifting arm cylinder were selected, and the hydraulic pressure of rodless chamber, rod chamber and piston displacement were actually tested when loader shovelling small stone, after analyzing and processing the measured hydraulic pressure and displacement with the soft-wares of Vib'SYS and nSoft, the change courses of the hydraulic pressure of rodless chamber, rod chamber and piston displacement of single typical operating cycle were obtained. In the paper, MATLAB soft was applied to fit the hy-draulic pressure and piston displacement at different operating segments of the obtained single typical operating cycle, and by the programming process, the power waveforms of different operating segments of lifting arm cylinder were ob-tained, after the power waveform of each work segment was merged according to the operating time order, the output power change characteristic curve of lifting arm cylinder when loader shovelling small stone was acquired. The analy-sis result showed that the provided determination method of lifting arm cylinder output power was feasible.
