摘　　要：采煤机的牵引部作为采煤机的执行机构,在往复牵引采煤机行走的过程中,载荷波动剧烈,轮齿负载过大,易造成轮齿断裂缺口,设备损坏。针对其牵引机构受力复杂情况,用Adams及相关软件,对采煤机建立虚拟机模型,依据模型对其牵引机构进行了动力学分析,针对行走轮与销排受力分析,采用遗传算法迭代选取最优参数,并以此参数更改原模型进行动力学分析。仿真实验证明,与原模型相比,优化后行走轮齿根部应力减小了15%,轮表面接触应力减小了12.5%,应力的降低减轻了行走轮与销排的磨损,确保了采煤机的安全作业。As the executive mechanism of the shearer,the traction part of the shearer fluctuates violently in the process of reciprocating traction of the shearer,and the load on the teeth is too large,which is easy to cause tooth fracture and notch and equipment damage.In view of the complex force of its traction mechanism.Using Adams and related software,the virtual machine model of shearer is established,and the dynamic analysis of its traction mechanism is carried out according to the model.For the force analysis of walking wheel and pin row,the genetic algorithm is used to iteratively select the optimal parameters,and the original model is changed with this parameter for dynamic analysis.The simulation results show that compared with the original model,the optimized walking gear root stress is reduced by 15%,the wheel surface contact stress is reduced by 12.5%,the reduction of stress reduces the wear of walking wheel and pin row,and ensures the safe operation of shearer.
