【摘要】 讨论了轮式起重机伸缩臂倒置伸缩液压缸的稳定性的计算方法。在考虑缸筒对活塞杆的约束作用时,不仅考虑了缸筒的弯曲刚度,还计入了液压油对缸筒弯曲刚度的影响,从而使计算结果更接近实际情况。最后还给出了计算程序框图,以便应用时参考。更多还原

【Abstract】 The stability calculation methods of inversely mounted telescopic hydraulic cylinder in mobile crane are discussed. In the study of the restrictive effect of the cylinder body on the piston rod, not only the flexural rigidity of cylinder, but also the effect of hydraulic fluid on the flexural rigidity in cylinder are considered, so that the result is much closer to reality. The block diagram of calculation program is presented for reference.更多还原
