【摘要】 剖析如何从细长压杆临界力的定义出发,找到一种基于压杆失稳定义的压杆稳定临界力测试方法,探讨了实验准确测得压杆稳定临界力的条件,总结了自制实验教学设备的体会。
【Abstract】 Analyse how to find a testing method based on the definition of the loss stability of the compressive column according to the definition of long and thin slender compressive column’s critical load.Talk over the conditions of obtaining the long and thin slender compression rod’s critical pressure exactly,summed up the self-understanding of making equipment used in experimental teaching.
【Key words】 the stability of the compressive bar; Euler formula; lateral bracing; lateral disturbance;
