代码说明:

针对问题一:为了描述折叠桌的动态变化过程,我们以外侧桌腿和地面的夹角为参数,建立了每条桌腿末端坐标的参数方程。利用Matlab软件求解,通过参数的连续变化,描述了折叠桌的动态变化过程,并且绘出了此动态变化过程中桌脚边缘线的变化轨迹图,同时得到了桌腿木条开槽的长度的设计加工参数。 针对问题二:通过分析,根据桌子结构的稳定性、用料最省、加工简便的要求,我们选用触地的四条腿所围的矩形面积、所有桌腿开槽长度之和、实木平板的面积分别对其进行刻画。以此作为优化指标,以最外侧桌腿长、最外侧桌腿长截余距离(见符号说明)、钢筋的位置为决策变量,建立了多目标规划模型。利用Lingo软件求解,我们得到了最优设计加工参数。 针对问题三:我们采用 请点击左侧文件开始预览 !预览只提供20%的代码片段,完整代码需下载后查看 加载中 侵权举报

    说明:  A commonly used control device called a programmable logic controller, or a PLC, is used to read a set of digital and analog inputs, apply a set of logic statements, and generate a set of analog and digital outputs. Using the example in the previous paragraph, the room temperature would be an input to the PLC. The logical statements would compare the setpoint to the input temperature and determine whether more or less heating was necessary to keep the temperature constant. A PLC output would then either open or close the hot water valve, an incremental amount, depending on whether more or less hot water was needed. Larger more complex systems can be controlled by a Distributed Control System (DCS) or SCADA system.
