摘要
液压传动广泛应用于各种工程机械,液压系统在工作时散热不足将导致系统温升超限,影响正常工作。该课题从解决某矿井用机械设备温升超限入手,对系统进行热平衡分析,在此基础上建立了热平衡时的散热器面积计算公式,求解出需要匹配的散热面积,利用Matlab/Simulink对平衡时系统的能量,能量变化率及温度进行仿真,结果表明计算结果正确。该匹配方法可以在其它液压系统匹配散热器时作为参考。
Hydraulic transmission is widely applied in variety of engineering machinery,shortage of heat dissipation lead to overrun of the temperature rise,affect the normal work.This topic aims to solve temperature overrun of a mine machinery,use measurement method to calculate the heating power of the system,give analysis of thermal equilibrium,Establish the thermal equilibrium calculation formula of the radiator area based on the analysis of the thermal equilibrium.simulate the thermal equilibrium use Matlab/Simulink.Calculates the radiator area required.The calculation formula established of the radiator area acts as a reference for other matching.
