This paper simulates how the additional flutter signal impacts on oil pressure and actuator output when the dead zone is kept. The proper principle of flutter signal for jam diagnosis is given. Based on the given flutter signal, different jams caused by jam of the EH servo valve under different operating condition are simulated and the output of the oil pressure and actuator are presented. Meanwhile, waving threshold of the oil pressure for jam diagnosis is given. The simulations and analysis prove that the jam fault identification of the EH servo valve based on flutter signal is feasible.

These features, along with high-precision processing technologies have helped to miniaturise these products. The micropump is 6.0mm in diameter and 24.0mm in length, the microvalve measures 3.5mm in diameter and 10.3mm in length. The products are small but ensure high functionality by incorporating fluid, structure and magnetic field analysis simulations. Development will contribute to enhanced miniaturisation, an indispensable prerequisite for portable device fuel cells. Through the optimal design of diaphragm operations, valve configuration to prevent fluid backflow, materials and layout, Alps has achieved the effective control of larger amounts of fluid in a smaller chassis for its micropump. The unit also employs low-voltage electromagnetic drive systems, which contribute to easy control and fuel cell system engineering.
