发动机与液力变矩器匹配优化

Optimization of matching on hydraulic torque converter and diesel engine

运用最小二乘法对发动机外特性和液力变矩器的原始特性进行拟合,并依据发动机与液力变矩器的匹配原则,以装载机动力性为目标,建立了发动机与液力变矩器匹配的优化模型。最后以具体的应用实例进行了验证。

Base on the principle of matching between the engine and hydraulic toque converter,the optimum model was presented. In this model, numerical approximation of some characteristics of diesel engine and hydraulic toque converter were carried out by the method of least square ,and wheel loader power characteristic was taken as object. Besides ,the theory is proved by an example.
