A Testing Method of the compressive poles stable critical load based on the definition of instability of the compressive pole

摘要：

According to the definition of long and thin compressive poles critical pressure, analyzing the problems that exist in conventional experiments of the stability of the compressive pole, a testing method of the compressive poles stable critical load based on the definition of the loss stability of the compressive pole was given in this paper. By the way of adding a straight-line state adjustment and detection unit, the compressive pole can always keep a straight line balance state before it loss its stability. At the same time, by the way of adding a lateral disturbance device,. inducing the abrupt alterant loss stability phenomenon of the balance state of the compressive pole and explaining its destroy mechanism in the state of loss stability.

关键词： the stability of the compressive pole Euler formula lateral bracing lateral disturbance
