车用发动机曲轴扭振与整车传动系的相互关系

Study on the Calculation Model for Torsion Vibration of Crankshaft of Motor Vehicle Engine

为了使曲轴系统扭转振动计算能准确地反映出发动机装入载货车后扭振情况，应正确建立曲轴系统扭转振动计算数学模型和力学模型。对ＣＡ１１５０ＰＫ２Ｌ２Ｔ型载货车传动系统扭转振动进行当量系统的转化和计算，利用汽车传动系扭振计算程序对ＣＡ１１５０ＰＫ２Ｌ２Ｔ型载货汽车传动系进行了扭转振动计算。

To accurately reflect engine's torsion vibration in the truck,the right mathematical and mechanical model should be created for the calculation of crankshaft torsion vibration,Through transformation,the equivalent system has been created for the driving system of CA1150PK2L2T type motor truck,and torsion vibration calculation has been made for the truck's driving system using torsion vibration calculation program for the driving system of motor vehicles.
