【摘要】：通過(guò)課堂實(shí)物演示分析幫助學(xué)生掌握力學(xué)基本概念,基本規(guī)律,引導(dǎo)學(xué)生運(yùn)用力學(xué)原理分析力學(xué)現(xiàn)象,解決力學(xué)問(wèn)題,是在課堂教學(xué)環(huán)節(jié)培養(yǎng)學(xué)生創(chuàng)新能力的有效途徑.通過(guò)鋼卷尺演示分析開(kāi)口薄壁桿件中心壓桿失穩(wěn),側(cè)立彎曲失穩(wěn)及水平布置彎曲失穩(wěn)現(xiàn)象.分析了鋼卷尺水平布置彎曲時(shí),卷尺拉出長(zhǎng)度相同的條件下,截面弧形凸出一側(cè)向上時(shí)失穩(wěn),凸出一側(cè)向下時(shí)不失穩(wěn)的現(xiàn)象.
[Abstract]:Through classroom demonstration and analysis to help students master the basic concepts and laws of mechanics, guide students to use mechanics principles to analyze mechanical phenomena and solve mechanical problems. It is an effective way to cultivate students' creative ability in classroom teaching link. Through demonstration of steel tape measure, the instability phenomena of center compression bar, lateral bending instability and horizontal arrangement bending instability of open thin-walled members are analyzed. When steel tape tape is arranged horizontally, bending is analyzed. Under the condition of the same drawing length of the tape measure, the stability of one side of section arc protruding is unstable when up, and the phenomenon of no instability when one side is protruded down.
