针对高速运动机构的特点,补充考虑铰链式运动副间隙的机构运动可靠性分析模型,并以曲柄滑块机构为例,应用非连续接触模型和连续接触模型,详尽分析运动副径向间隙和销轴位置的不确定性因素对机构运动可靠性的影响。
The objective is to supplement the analytical model of mechanism moving reliability taking account of kinematics joint gap focusing on high velocity motion mechanism. Based on the theories of reliability engineering and mechanism probability design, the kinematical accuracy reliability for slider-crank mechanism taking account of kinematics joint gap are analyzed by the continual contacting model and the non-continual contacting model. As an example, the study about slider-crank mechanism is provided to show the relationship between joint-gap and kinematical reliability of mechanism.
