车组链输送机是一种新型的散状物料连续性输送设备。针对输送机关键结构中承载输送带并依托轨道运行的连续轨道车组在曲线工况处的曲线通过性能展开了研究。建立轨道车组曲线通过时的非线性动力学模型并进行分析。利用多体动力学仿真软件SIMPACK建立轨道车组模型,从不同的工况条件和轨道小车结构出发,分析轨道车组的曲线通过性能的变化。仿真结果表明,车组链输送机轨道车组在各工况下的动力学性能评价指标随着车速、车间距提高而减小,随曲线半径、缓和曲线长度的提高而增大;采用较小轴距轮对和铰接结构车体能够适应曲线轨道;轨道车组的曲线通过性能良好,各项指标都处于安全限度范围值之内。
Abstract The vehicle group chain conveyor is the new kind of continuous material conveying equipment in bulk materials field. For its essential structure, which is the continuous track group car carrying the conveyor belt and relying on the rail runs. Curve passing performance at curve working conditions is studied. A nonlinear dynamics model of the conveyor track group passing the curve is established and analyzed. The multi-body dynamics simulation software SIMPACK is used to build the track group car model. Based on the different working conditions and the structure of the car, the variation of the curve passing performance of the track car is analyzed. The simulation results show that dynamics performance index of the track car in vehicle group chain conveyor under various working conditions decreases with the increase of the vehicle speed and spacing, and increases with the increase of the curve radius and transition curve length. Track car with smaller wheelbase and articulated body can adapt to curved track. The curve of the track car has good performance and all indicators are within the safe limit range.
