1 设计课题
1.1设计目的
通过课程设计培养学生综合运用所学知识和技能、提高分析和解决实际问题能力的一个重要环节,专业课程设计是建立在专业基础课和专业方向课的基础上的,是学生根据所学课程进行的工程基本训练,课程设计的目的在于:
1、培养学生综合运用所学的基础理论和专业知识,独立进行机电控制系统(产品)的初步设计工作,并结合设计或试验研究课题进一步巩固和扩大知识领域。
2、培养学生搜集、阅读和综合分析参考资料,运用各种标准和工具书籍以及编写技术文件的能力,提高计算、绘图等基本技能。
3、培养学生掌握机电产品设计的一般程序和方法,进行工程师基本素质的训练。
4、树立正确的设计思想及严肃认真的工作作风。
1.2设计要求
执行元件:液压油缸;
传动方式:电液比例控制;
控制方式:PLC控制;
控制要求:速度控制;
控制精度:0.01
1.3设计参数
油缸工作行程——600 mm;
额定工作油压——6.5MPa;
移动负载质量——1000 kg;
负载移动阻力——5000 N;
移动速度控制——0.2m/s;
1.4 设计方案
利用设计参数和控制要求设计出液压油缸,进而设计出液压系统,通过PLC对液压油缸进行速度控制。 ...
