摘　　要：研究了电动铲运机工作过程中电缆张力的变化,提出了电缆动态张力的计算公式,根据现场实测的结果,提出了考虑路面不平度和铲运机振动时的修正系数,并计算了卷、放缆溢流阀开启压力的比值和电缆的最大冲击张力。The piece given here studies the tension changes of a electric LHD's cable in working and then establishes a formula for dynamic tension calculation of the cable. Depending on the results of testing on site the revising coefficients regarding the road plainness and vibration are offered. Finally the opening pressure ratio (cable reelling up to out) of the reel overflow valve and cable's max. shock tension are also calculated.
