水电水利工程中用于启闭各种闸门的液压缸具有工作行程大,活塞杆承受的拉、压荷载大,启闭操作的可靠性要求高等特点。实际应用中,计算其稳定性的资料很多,临界载荷取值相差很大。针对上述情况,提出了液压缸稳定性计算的新方法。将液压缸简化为二阶变截面的压杆,应用Matlab软件,得到液压缸临界载荷的校核公式。结果表明,所得到的计算结果简单方便,有利于人们在设计中的计算。

Hydraulic cylinder used for opening and closing various gate has features of long work schedule, high reliability of o ̄pening and closing operations, with its piston rod bearing high tension and pressure load in a hydropower project. In the actual application, a lot of materials are used to calculate the stability, but critical load values vary widely. Aiming at the above situa ̄tion, a new method is presented, which is used to calculate the stability of the hydraulic cylinder. The hydraulic cylinder is sim ̄plified as a second-order variable cross-compression bar, the formula of the critical load of the hydraulic cylinder is obtained by using Matlab software. The results show that the calculation result is obtained simply and conveniently. It helps people in the design calculation.
