新型立式曲柄导杆滑块实验台设计与研究

Design and Development of Vertical Crank Guide Rod Slide Block Experiment Table

为了满足机械设计与机械原理课程的教学需求,设计一种新型立式曲柄导杆滑块实验台。该实验台结构新颖,可快速拆装来改变结构参数,传动单元可视,方便学生观察。应用矩阵法建模,得出滑块位移、速度、加速度表达式,应用达朗伯原理,求解约束反力。通过UG建立三维模型,搭建虚拟样机,进行运动仿真。经过实验对比分析,仿真图像和实测图像波形与数据基本吻合,结果符合曲柄滑块运动学规律。该实验台不仅可以调动学生的积极性,增强对实验环节的参与感,还可以满足实验教学的需求。

In order to meet the teaching requirements of Mechanical Design and Mechanical Principles.A new type of vertical crank guide rod experiment table was designed.With the characteristics of new structure,quick disassembly,transmission unit visualization.It was easy for students to observe the connection characteristics and transmission characteristics.In order to obtain the curve of slider displacement,speed,and acceleration,the matrix method was used to build the model.The Constraint Reaction Force was solved with application of D’Alembert principle.Three-dimensional model was built by UG software for motion simulation to obtain the curve.Motion simulation functions was provided after the Test Data and Experimental Data was compared.The results shows that the displacement,velocity and acceleration of the crank slider are basically consistent with the data.It can mobilize the enthusiasm of students,enhance the students'participation in the experimental process,to meet the needs of experimental teaching.
