摘要
本论文分析了阀控非对称油缸在正反向阀开口量相等时 ,其正反向油缸速度比并不等于油缸面积比 η。在空载时等于 η;而在有常力负载时等于 ηps+po/ps-po。
The positive - to - negative velocity ratio is not equal to the area ratio η of the cylinder when the positivevalve opening is equal to the negative. In the no - load case, the velocity ratio equals to η′η, while in the caseof constant force losd, equals to η′, where the η′is a constant(ηP o + P o)/(P s-P o)related to load force p o, oilsupply pressure p s. and the cylinder area ratio η.\;
