对曲柄滑块机构进行了几何分析并确定了其设计参数的取值范围。基于Pro/E的Top-Down设计方法,建立了曲柄滑块机构的骨架模型。通过Pro/Program编程和添加关系式实现了骨架模型参数化设计。基于骨架模型建立了曲柄滑块机构装配模型,并在Pro/Mechanism模块中进行运动学仿真分析,成功地建立了一个参数化设计与仿真系统。该系统能够获取曲柄滑块机构任意位置的运动规律,具有可视化、参数化、操作简单等特点,为教学与生产实践提供指导。
Geometric analysis is done and value ranges of design parameters are confirmed for Slider-crank Mechanism.Based on the Top-Down design in Pro/E,the skeleton model for slider-crank Mechanism is built.And parametric design for the skeleton model is realized by programming and adding relations in Pro/Program.Based on the skeleton model,an assembly model is built,and is kinematically simulated in Pro/Mechanism.So a parametric design and simulation system for slider-crank mechanism is finally established.With this system,movement law in any position of slider-crank mechanism can be obtained.This system is characterized with its visualization and parameterization and easy operation,which may provide guidance for teaching and productive practice.
