To estimate the influence of the flatness ratio on hydrodynamic performance , a group of torque converters with different widths were investigated by cfd simulation to improve the power diversity and reduce the mass based on the variable - width circulatory circle torque converter design method 摘要在變寬度循環(huán)圓設(shè)計(jì)方法的基礎(chǔ)上,為提高液力傳動(dòng)系統(tǒng)功率密度,減輕質(zhì)量,對(duì)幾組不同寬度比循環(huán)圓的變矩器進(jìn)行了cfd (計(jì)算流體動(dòng)力學(xué))數(shù)值模擬,借以評(píng)估對(duì)其整體傳動(dòng)性能的影響。
