To meet the needs of L-type large torque and high-speed planetary gear reducer, a test-bed is designed. During the period of working out, the scheme of hardware structures of the reducer test-bed is discussed, and then the close-type power flow test-bed is chosen. Finally, concrete ways of reducer positioning, power and loading device fixing, and the assembly of test-bed hardware is defined. At the...
This paper introduces in detail the measurement and controlling system of wind turbine pitch bearing test-bed from test principle, hardware construct and software design. This system includes the modules of bearing rotary motion control, axial and radial hydraulic cylinder load control, test data acquisition and analysis. Using IPC as the hardware platform, with data acquisition card, sensors, hydraulic...
This is the second part of the two-part paper to illustrate the control system design and multi-energy strategy, it is the key to fulfill the fuel economy target for ISG hybrid bus. Based on a hierarchical structure, the control system is developed with the HCU (hybrid control unit) as the central controller to coordinate the motor, engine and CAN communication protocol. The multi-energy control strategy...
