1、科类工科本科生毕业设计基于MATLAB的曲柄滑块机构模拟与仿真BasedontheMATLABslider-crankmechanismmodelingandsimulation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。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
2、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。可以方便地实现对机构的运动分析及模拟。本设计应用MATLABGUI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。关键词：滑块机构、MATLAB、GUI26BasedOntheMATLABSlider-crankMechani
