摘要
通过控制压力铸造充型速度来改善汽车发动机缸体铸件力学性能,提高发动机缸体铸件品质。采用可编程控制(PLC)控制压力铸造的充型速度,克服了充型过程中速度波动幅度大的缺点。采取MATLAB软件对压力铸造充型速度进行仿真,并与PD控制方式仿真结果进行比较和分析。仿真结果证明:采取PLC控制发动机缸体压力铸造充型速度,充型速度波动幅度较小,充型过程相对稳定。
Appropriate controlling the filling speed of the pressure casting can improve the mechanical properties of the automobile engine cylinder block and improve the quality of the engine cylinder block castings. In this paper, the process flow of engine cylinder pressure casting was analyzed, and the whole scheme of pressure casting control system was designed. According to the control target using PLC control method, MATLAB software was adopted to simulate the filling velocity of pressure casting, and the simulation results were compared and analyzed with the PD control method. The results show that adopting PLC to control engine cylinder pressure and filling velocity, the filling velocity fluctuation amplitude is smaller, the filling process is relatively stable.
