[동력전달계부문] HIVEC 4속 자동변속기 변속특성해석 (Part 1) - 동력전달계 요소해석 -

This paper describes the analysis of the shift characteristics of the HIVEC automatic transmission. Analytical models of the power train components, such as, engine, torque converter, valve body(hydraulic control system), geartrain, clutches and brakes, are derived and solved in the case of HIVEC automatic transmission. Simulation results for torque converter and valve body are compared with the test results, which shows comparatively good agreement. These models of the power train components are used to analyze the shift characteristics of HIVEC automatic transmission in the Part 2.
