| 摘 要： | 比照测试柴油机负荷特性方法对某型废气涡轮增压柴油机进行了全工况热平衡台架试验,并以柴油机各稳定工况点台架试验的转速、加油尺杆位移、排气温度及相应输出扭矩的测试数据为训练、测试样本,通过BP神经网络的反复学习,得到了精度较高且泛化能力较强的柴油机动态输出扭矩预测模型。

| Abstract: | The full-conditions heat balance bench test of a certain type of exhaust-gas turbo-charged diesel engine is carried out according to load-characteristic test rules of diesel engine. Taking the rotation speed,oiling teeth bar displacement,exhaust gas temperature and corresponding output torque testing data of each steady working condition bench test as training sample and testing sample,a high precision and strong generalization predictive model for dynamic torque of diesel engine is established by repeatedl... |
