HST 중립밸브 해석모델 개발 및 민감도 해석

The neutral valve as the controller of HST is one of important valves for the vehicle control. The neutral valve is the valve performing the role to transmit or block the power to the vehicle. The logical validity has been investigated by analyzing the serve circuit through the development of analytical model of neutral valve. The modelling used the simulationX as the commercial software. The analysis for the number of piston hole of Orifice Diameter, the size of pressure pulsation and the initial amount of compression have been performed in the sensitivity analysis of each design variable of this study.
