摘要
剪刀架机构大量应用于民航领域特种设备中。从机构学出发,以剪刀架单元为研究对象,通过分析自由度和建立输出、输入运动方程,研究剪刀架单元的运动学位置方程。提出行程放大系数与最大行程两个指标,用来评价不同输入方式的效率。结合实际应用,对现有输入方式进行比较,结果表明支臂间输入方式具有最优性能。
There have many scissors mechanisms existing in special devices of civil aviation.Based on mechanism theory,kinematics formulas of scissors unit were investigated through analyzing DOF and building input/output equations.Two parameters：stroke amplification factor and maximum stroke value were proposed to assess performance of different input configurations.Combining current applications,input configuration with best performance is the input configuration between left arm and right arm by comparing input configurations.
