本文对国产ZJ45钻机现场测试的部分结果进行了分析。说明了提升系统动载荷相对时间的变化规律,提出动载系数的数值和影响动载系数的因素,并对ZJ45和ZJ45J两种钻机动载系数的测试结果进行了比较。
This paper analyzes some of the field test results of domestic ZJ45 rig. The change law of the dynamic load of lifting system relative to time is described. The numerical value of dynamic load coefficient and the factors affecting the dynamic load factor are proposed. The test results of the dynamic load factors of ZJ45 and ZJ45J are compared.
