摘要
本文先采用挠曲线精确微分方程求出细长压杆临界力,再与用欧拉公式求出的细长压杆临界力进行比较,得出“欧拉公式求压杆临界力的精确度很高”的结论。
This thesis has evaluated a critical force on the long and thin press bar by making use of the precise differential equation concerning the flexible curve at first, and then compared the critical force with another critical force on the long and thin press bar by means of Ora Formula. Hence, from this it has drawn a conclusion that the precision of the critical force on the press bar evealuated by means of Ora Formula proved to be very high.
