摘要
研究了一种架空轨道穿梭车,可用于多种工业场合的物料运输。为了提高穿梭车的工作效率,减小轨道垂向不平顺引起的车身垂向振动,基于H 2优化确定了悬架的最优参数,使车身垂向振动的能量最小。为验证悬架参数的合理性,分别对1/4车模型和整车模型进行仿真。对1/4车模型进行数值仿真,仿真结果验证了参数的合理性。基于Simpack建立了整车的多体动力学模型,利用根轨迹法计算了整车模型在美国六级轨道谱下失稳的临界速度,仿真结果满足设计要求,再次验证了参数的合理性。
In this paper,the aerial rail shuttle was studied,which can be used in various industrial applications,such as underground mine transportation,unmanned warehouse and production line of precast concrete components.Moreover,in order to improve the work efficiency of shuttle vehicle and ameliorate the vibration caused by vertical track irregularity,the optimal parameters of suspension are obtained based on H_(2) optimization,i.e.,the stiffness and damping which can minimize the vibration energy.Finally,the quarter vehicle model and whole vehicle model are simulated respectively,and both simulation results verify the correctness of the parameter optimization results.
