软硬结合的连续系统模拟实验设计与实践

结合新工科建设和课程教学创新需求,研究并设计了软硬结合的连续系统模拟实验。以模拟仿真为主、实测验证为辅,引导学生使用运算放大器组成的基本运算模块搭建实际系统对应的模拟系统,使用Multisim软件虚拟仪器对模拟系统进行时域和频域性能观测,并通过实验板进行实测验证。内容设计与教学导引具有良好的层次性与自主性,激发了学生课程学习的兴趣,在本科生电工电子实践教学中取得了良好效果。

The continuous excavating technique system parameters optimization and economic assessment simulation model in open-pit mine

Based on the fundamental simulation theories and methods, this paper studies such questions as truck dispatching, discrete processing of belt system continuous haulage, belt system interlock, and economic assessment methods. On the basis of above studies, the paper establishes a simulation model for open pit mine semi continuous production technique system. The paper applies GPSS language to construct a simulation program, and the program has been successfully applied in a certain coalmine.
