适用于“双8”轨迹的凸轮机构及其设计方法
|
摘要
该文以实现"全国大学生工程训练综合能力竞赛"赛题规定中的无碳小车连续交替绕过中线上3个间距相同的障碍桩走"双8"字形轨迹为目的,灵活运用MATLAB,Solid Works和ANSYS等建模仿真工具,系统经历了从理论分析,做出假设,公式推导,到3D建模,再到仿真选材,最后到结果检查的完整过程,设计出了一种可普遍适用的转向调节机构——摆动从动件盘形凸轮机构。它在具有简单、紧凑结构特点的同时,也具有稳定、可靠的工作状态,可以轻松实现不同的"双8"字形轨迹,并达到周期性重复绕障的目的。这种凸轮机构及其设计方法在应对赛题的变化上,以及满足其他行业发展的需求上,也有一定的普遍适用性和应用前景。
This article aims to solve the problem in the National Undergraduate Engineering Training Integration Ability Competition-realize the carbon-free car's "double 8" trajectory by continuously and alternately bypassing the three obstacles with the same spacing on the center line. During the complete process from theoretical analysis,hypothesis,formula derivation,3D modeling,simulation and selection of materials to the results of inspection,and a widely-used steering-adjustment mechanism—CAM mechanism with an oscillating follower disc is developed by means of MATLAB,Solid Works and ANSYS and other tools. The mechanism,with a simple and compact structure,boasts its stable and reliable working state; it can easily realize different "double 8" trajectories for multiple times. The mechanism and its design method can be widely adopted in the competition and other industries.
