Abstract
Hybrid Hydraulic Vehicle (HHV) is quite popular in automotive industry for hybrid technology. However, the system is facing a problem in controlling the RPM since HHV has limited storage energy to store high-pressure thus it results to unstable behavior of RPM and only able to operate in short period of time. Therefore, the aim of this study is to determine the RPM profile behavior with metering in and out and also to compare the result between without metering and with metering in and out. The circuit diagram is designed and simulated by using the hydraulic tool in the Automation Studio software. A simulation towards both systems in the hydro-pneumatic driveline is carried out to observe the behavior of RPM. For system with metering, a flow control valve with check valve is installed before and after the hydraulic motor to be metered in and out. Besides, pressure storage inside the accumulator will be vary from 120 bar until 220 bar to observe the behavior of RPM in the hydro-pneumatic driveline and data will then be taken out. Through the simulation, metering in and out shows better performance compared to a system without metering since metering in and out has proved that the system can effectively control the behavior of RPM. The peak reading of radial speed for system with metering in and out is 2809.48 rpm and the discharge time is 8.2 s which is the radial speed is lower and the discharge time is longer than a system with no metering. This discharge time is good to power mild and medium type of hybrid system.
