[동력전달계] 건설차량용 자동변속기 동력전달장치의 모델링 및 해석 = The Modeling and Analysis of the Powertrain in a Automatic Transmission for the Construction Vehicle

다국어 초록 (Multilingual Abstract)

In general. the transient torque takes place when the gear shifts in the vehicle equipped with automatic transmission. The modeling of the powertrain is necessary for design the control algorithm to decrease the transient torque. In this study, the modeling of powertrain dynamics for the construction vehicle is established and the velocity analysis is accomplished. Automatic transmission for this system is ALT(Automotive Layshaft Transmission) type and has many shafts and rotating members. So the velocity analysis is achieved by classitying all element into three rotating groups and dynamic modeling is accomplished with three equivalent inertia models that are always in gear with each other. And the transient shift model is obtained by using this equivalent inertia model and the kinematic constraints for each gear shift. Also, the torque and pressure of each element which is required when the gear shifts can be obtained by static characteristic analysis and the minimum line pressure in hydraulic system can be set up through this result.
