基于MATLAB的曲柄滑块机构模拟与仿真

摘要

用曲柄和滑块来实现转动和移动相互转换的平面连杆机构，也称曲柄连杆机构。曲柄滑块机构中与机架构成移动副的构件为滑块，通过转动副联接曲柄和滑块的构件为连杆。曲柄滑块机构广泛应用于往复活塞式发动机、压缩机、冲床等的主机构中。桥梁支座更换与维修是机械传动中必不可少的组成部分。MATLAB 的应用范围非常广，包括信号和图像处理、通讯、控制系统设计、测试和测量、财务建模和分析以及计算生物学等众多应用领域。附加的工具箱（单独提供的专用MATLAB 函数集）扩展了MATLAB 环境，以解决这些应用领域内特定类型的问题。放血刀深基坑防护可以方便地实现对机构的运动分析及模拟。 hca2

本设计应用MATLAB GUI设计工具和M程序结合，进行平面四杆机构的运动分析，通过GUI实现界面的设计，通过M程序完成程序的编制和调试，并通过接口实现了滑块机构的运动分析及模拟，界面运行时判断出机构类型并显示从动杆、滑块的瞬时角速度、瞬时角加速度、极位夹角、最小传动角及反正行程速比系数。

And with the crank slider to realize the rotation and mobile transformation planar linkage mechanism, also say to crank rod system. Slider-crank mechanism with a frame in the m

ovement, component for the slider, through the rotation crank slider and vice connection of components for connecting rod. Slider-crank mechanism is widely used in reciprocating compressor, piston engines, the institutions of the punches, etc. Is the mechanical transmission in the indispensable part.MATLAB application range is very wide, including signal and image processing, communication, control system design, test and measurement, financial modeling and analysis and computational biology for many applications. Additional toolbox (provide individual special MATLAB function set) expanded the MATLAB environment, in order to solve these applications in the particular type of problem. It can realize the movement of the mechanism analysis and simulation.

This design MATLAB GUI design tools and M program combination, the movement of planar four-bar linkage analysis, through the GUI realize interface design, through the M program complete programming and commissioning, and through the interface implementation the slider mechanism analysis and simulation of movement, interface operation mechanism type and judge the pole, the slider shows the driven the instantaneous angular velocity, instantaneous Angle acceleration, extreme position Angle,

minimum transmission Angle and anyway, the stroke ratio coefficient.

Keywords: slider mechanism, MATLAB, GUI
