在第一篇中,推导出了“阀控非对称油缸的频率特性”的基本方程,并求得了数值结果,另一方面,假定负载压力在半个周期内几乎保持不变,推导出了其近似方程。在本研究中对“阀控非对称油缸的频率特性”进行了试验分析。试验用的是东京精密测器(株)生产的3F-60L-30型电液伺服阀,其额定流量为60升/分,许用最大电流为30毫安。在液压源的输出压力保持10兆帕,电液伺服阀的输入电流频率范围为2～30赫的工况
In the first chapter, we deduced the basic equation of “the frequency characteristics of the valve-controlled asymmetric cylinder” and obtained the numerical results. On the other hand, assuming that the load pressure remained almost unchanged within half a cycle, we deduced that Approximate equation In this study, the “valve-controlled asymmetric cylinder frequency characteristics” were analyzed. The test was performed on a 3F-60L-30 electro-hydraulic servo valve manufactured by Tokyo Seimitsu Co., Ltd. Its rated flow rate was 60 L / min and the allowable maximum current was 30 mA. The output pressure of the hydraulic source to maintain 10 MPa, electro-hydraulic servo valve input current frequency range of 2 to 30 Hz conditions
