针对用AMESim建立系统模型时存在的问题,提出基于AMESim优化功能的参数识别建模方法。采用该方法建立某型注塑机注射回路的模型(使用AMESim软件的超级元件功能简化了模型),说明建模的详细步骤,重点阐述如何应用AMESim的优化功能识别系统的未知重要参数,以完善仿真模型。实验和仿真数据的对比说明,使用该方法建立的模型比较吻合真实模型。

Aiming at the existing problems of establishing system model based on AMESim, the modeling with parameter identification based on the optimization function of AMESim was put forward. The injection loop of an injection molding machine was modeled adopting the modeling method （the model was simplified by using the super-component function of AMESim）, and the detailed steps of the modeling with the method were illustrated. How to use optimization function of AMESim to identify the system＇ s unknown important parameters was mainly expatiated in order to improve the simulation model. By comparing experiment data with simulation data, it shows that the model modeled with the method is more consistent with the actual model.
