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)圓設計方法的基礎上,為提高液力傳動系統(tǒng)功率密度,減輕質(zhì)量,對幾組不同寬度比循環(huán)圓的變矩器進行了cfd (計算流體動力學)數(shù)值模擬,借以評估對其整體傳動性能的影響。
