簡析等臂式三輥抱芯裝置的設(shè)計

Brief Discussion on Design of Three-roll Mandrel Steadier

摘要: 現(xiàn)行的等臂式三輥抱芯裝置設(shè)計方法存在設(shè)計周期長、設(shè)計精度低等問題。為了優(yōu)化設(shè)計方法,以機(jī)械原理為基礎(chǔ),建立了一種等臂式三輥抱芯裝置數(shù)學(xué)模型,其結(jié)構(gòu)設(shè)計為傳動比為-1的四連桿機(jī)構(gòu);并利用Matlab優(yōu)化工具對該模型進(jìn)行了優(yōu)化計算。通過優(yōu)化設(shè)計,使等臂式三輥抱芯裝置的實際中心與軋制中心重合度提高,傳動條件改善,設(shè)計周期縮短,設(shè)備使用壽命提高。

Abstract: The design process of the currently-used equal-arm three-roll mandrel steadier stays with such problems as long design work cycle and low design accuracy,etc. To optimize the said design process,based on relevant mechanical principle,the math model of an equal arm three-roll mandrel steadier with a structure designed as a four linkage mechanism with a drive ratio of-1 is set up. Furthermore,the math model is optimized with the Matlab optimizing tool. Owing to the optimized design,the overlap ratio between the actual center of the above mentioned mandrel steadier and the rolling center is enhanced,the drive conditions improved,the design work cycle shortened,and the service life extended.
