|
摘要
针对矿井提升机制动过程中的钢丝绳张力变化大的特点,本文基于虚拟样机技术,运用RecurDyn多体动力学仿真软件建立了提升机虚拟样机模型;基于此模型研究了重载提升工况和重载下放工况制动过程中钢丝绳张力变化规律,结果表明:重载下放工况制动过程中钢丝绳张力大于重载提升工况下钢丝绳张力。
In view of the large variation of the tension of wire rope during the braking process of mine hoist, a virtual prototype model of hoist is built used the software of RecurDyn based on virtual prototyping technology. Based on this model, the change law of wire rope tension during the working condition of heavy load lifting and heavy load is researched. The results show that the wire rope tension of heavy load down condition is greater than the tension under heavy load lifting during the braking process.
