利用相似理论研究大挠度屈曲簧片

THE APPLICATION of PRINCIPLE of SIMILITUDE to RESEARCHING the LARGE DEFLECTION BUCKLING SPRING-PIECE

大挠度屈曲簧片的静特性曲线在力学上属于变截面拱的非线性问题,要在理论上获得簧片的静特性曲线至今是困难的。本文运用相似理论和模型试验方法,获得了一组设计簧片的计算公式,可应用于工程设计。

The static characteristic curve of the Large Deflection Buckling Spring-piece (which is called 'LDBSP'for short), belongs to the nonlinear problem of varying section arch in mechanics. It is very difficulty in theorizing the static characteristic curve of LDBSP. The formulas for designing LDBSP obtained by the use of the principle of similitude and the model experiment method, can be used in engineering design.
