摘要：

以国内某先进乘用车工厂的冲压车间为背景，针对该车间生产物流流程，利用西门子Plant Simulation软件进行仿真模拟，得出在给定生产计划前提下的最佳物流转运设备台数与冲压线线尾装箱工人数量等数据，并分析了该冲压生产线的极限产能情况，同时，验证了规划毛坯库与冲压件库面积可满足车间的正常生产需求。仿真结果表明：该条冲压线极限产能最大可达年产15万辆整车的生产纲领，此时的生产负荷率为90%左右；冲压线线尾装箱工人数量在6~8名最为合适；冲压线线尾转运叉车数量在3~5台为宜；毛坯库面积约为900 m2,可满足生产需求，每种毛坯最大可按3层或4层分层存储；冲压件库面积约为4100 m2，可满足焊装车间的生产需求，此时冲压件库可存储1个批次的生产计划量。将本次仿真结果应用于车间实际生产，为车间管理方面遇到的诸如工人数量、存储面积、物流设备台数规划等方面的问题提供了切实可行的解决方案。

For the stamping workshop of a domestic advanced passenger car factory, the production logistics process of the workshop was simulated by software Plant Simulation of Siemens, and the number of optimal logistics transfer equipment and the number of packing workers at the end of stamping production line under the premise of a given production plan were obtained. Then, the maximum production capacity of the stamping line was analyzed, and the planned warehouse areas of blank and stamping part were verified to meet the normal production requirements of the workshop. The simulation results show that the maximum production capacity of this stamping line reaches 150000 vehicles per year, at this time the stamping line load rate is about 90%, the number of packing workers at the end of stamping line is most suitable for 6-8, the number of transfer forklifts at the end of stamping line is preferably 3-5, the area of blank warehouse is about 900 m2 to meet the production needs, each kind of blank is stored in three or four layers at most, the area of stamping part warehouse is about 4100 m2 to meet the production needs of the welding workshop, at this time the production plan of one batch is stored in the stamping part warehouse. The simulation results are used to guide the actual production of the workshop and provide practical solutions for the problems such as the number of workers, the storage area and the number of logistics equipment in workshop management.
