采用模糊數(shù)學(xué)的方法對低矮式破碎機偏心軸的截面尺寸進行了優(yōu)化設(shè)計,在滿足安裝條件和傳動性能要求條件下,使得偏心軸質(zhì)量最小.在優(yōu)化設(shè)計方案中考慮了影響設(shè)計的模糊因素,建立了模糊優(yōu)化設(shè)計的數(shù)學(xué)模型,并給出了基于Matlab的優(yōu)化方法和結(jié)果分析.

　　0引言偏心軸是破碎機中的一個十分重要的零件.軸在進人斷裂失效之前，經(jīng)歷了一個從“完好”到“失效”的逐漸過渡過程，即隨著使用時間的延長，應(yīng)力不斷地循環(huán)，因疲勞而產(chǎn)生微裂紋;在循環(huán)應(yīng)力作用下，微裂紋不斷擴展，逐漸發(fā)展成宏觀裂紋，直至最終導(dǎo)致斷裂而失效.從“完好”
