摘要
采用了较为合理、简单的液压缸计算模型,分析了液压缸各主要部分对其静力稳定的影响,基于小挠度稳定性理论,应用最小势能原理,得到临界压力近似计算方法,通过计算实例表明,该计算方法的计算过程比较简单,且计算精度很高。
In the paper,a simple and reasonable computational model of the hydraulic cylinder is built,and influences of each component of the hydraulic cylinder on the static stability of the cylinder are analysed.Based on small deflection stability theory,the theory of minimum potential energy is used to obtain an approximate method of computing critical pressure.The computation example shows that the calculation method is simple and quite accurate.
