摘要：為了揭示物料運(yùn)動(dòng)規(guī)律與葉片式拋送裝置功耗及拋送效率之間的關(guān)系，從而降低葉片式拋送裝置功耗、提高拋送效率，采用理論分析、虛擬樣機(jī)技術(shù)與高速攝像技術(shù)相結(jié)合的方法對(duì)物料沿拋送葉片的運(yùn)動(dòng)進(jìn)行研究。建立了適合前傾、后傾及徑向葉片的物料沿拋送葉片運(yùn)動(dòng)的動(dòng)力學(xué)模型及ADAMS模型，為了綜合考慮氣流對(duì)物料以及物料間的相互作用引入當(dāng)量摩擦系數(shù)，通過與高速攝像試驗(yàn)數(shù)據(jù)進(jìn)行回歸分析得到當(dāng)量摩擦系數(shù)的值，進(jìn)而對(duì)動(dòng)力學(xué)模型及ADAMS模型進(jìn)行了修正。通過分析功耗及拋送效率與物料運(yùn)動(dòng)規(guī)律之間的關(guān)系，獲得了物料最佳拋出角范圍約為60° ~130°。該研究為葉片式拋送裝置參數(shù)優(yōu)化奠定了基礎(chǔ)。 Abstract: To reveal the relationship between material movement rules and power consumption and throwing/blowing efficiency of an impeller blower, theory analysis, virtual prototyping and high speed photograph technology were used to study the material movement rules along paddles. Dynamic equations of materials along paddles were established and the movement of materials was numerically simulated with the adoption of computer dynamic software ADAMS, which adapted to all kinds of mounting angle of blade. Through the analysis of the relationship between material movement rules and power consumption and throwing/blowing efficiency, the material-threw angle at its optimal range was obtained, which was from 60 degree to 130 degree. The results can provide effective references to the further optimization of the working parameters of impeller blowers. |
