摘要:

为了避免气缸运动过程中出现爬行现象, 应用试验分析供气压力、节流口声速流导、外作用力、以及进气腔初始体积在实际应用中对气缸爬行的影响. 通过对爬行现象的分析及现有的研究提出爬行判据, 以此判据为依据设计不同工况下的临界爬行试验. 对试验曲线进行观察发现,气缸最终趋于匀速运动. 通过对临界爬行试验数据进行多项式曲面拟合, 得到以供气压力、节流口声速流导以及外作用力为参数的气缸爬行经验判别函数式. 为了验证该判别函数式的有效性和可行性, 对另一个同型号的气缸进行多次试验.结果表明,采用该经验判别函数式能够有效地预测不同供气压力、节流口声速流导及外作用力下同型号气缸是否产生爬行现象.

Abstract:

Stickslip influence factors in practical application, such as supply pressure, sonic conductance of orifice, external force and initial volume of inlet chamber, were experimentally analyzed in order to avoid stick-slip phenomenon encountered in pneumatic cylinder. The critical stick-slip experiments of different working conditions were conducted based on the stick-slip criterion concluded from existing studies and analysis of the stickslip phenomenon. The observation of the experimental curves shows that the final piston velocity is constant. An empirical discriminant function with supply pressure, sonic conductance of orifice and external force as parameters was established by processing the critical stick-slip experimental data for polynomial surface fitting, and its validity and feasibility were verified by performing experiments with another pneumatic cylinder of the same type. Results show that the empirical discriminant function can be used for instructing practical engineering applications by efficiently predicting whether the stick-slip will occur or not for the same type pneumatic cylinder with different supply pressures, sonic conductance of orifices and external forces.
