The paper based on the diesel CA6DL2–35E3 of FAW R&DC with turbocharger, intercooler, four-valve, six-cylinder and high pressure common rail, the diesel displacement is 8.6L. We had established model of the diesel with GT-power and simulated diesel engine working process under transient operating conditions which in constant speed while torque increased. We investigated and analyzed condition...
In order to model the gearbox and global wind turbine system with higher accuracy in short time, this paper focuses on the methods of multi-body dynamic modeling and wind turbine dynamic simulation on the platform of S4WT. By introducing the multibody system and super element approach, a steady-state response is simulated on one 1.5MW gearbox. Through calling S4WT parametric model, a dynamic response...
In this paper, KZQ-36T-300 multi-model controller is used for separate excitation electric motor which is used for material handing electric vehicle. It can control the motor rate and torque to make it in smooth, mute and low. The electromotor ECU testing system aim at the feature of KZQ-36T-300 multi-model controller, imitate many different road and working condition, imitate accelerator output the...
In view of the deficiency of the endurance mileage of pure electric vehicle, parameter design and related analysis of powertrain for extended-range electric vehicle including power drive system, energy storage system and range extender were conducted. Based on Matlab/Simulink, model of extended-range electric vehicle was built and simulation was carried out in the NEDC driving cycle. The simulation...
In CNC machining with high efficiency and high-precision, repeated positioning operation will not only affect the processing efficiency, but also make precision difficult to guarantee. Companies want to have an effective way to solve such problems, or can make up for lack of range of processing defects. We found that the system with built-in functions, if appropriate detection and protection components...
Direct Torque Control(DTC) technology is a high-performance communication control method, to obtain high torque dynamic performance, DTC technology uses the space voltage vector method, and then to the inverter switch state control. But none of the switching states is able to generate the exact voltage vector to produce the desired changes in torque and flux in most of the switching instances. This...
A system-level model of double-fed induction generator wind turbine is established based on AMESim in this paper. The sub-models are wind, drive train, double-fed induction generator (DFIG) and control models. A gearbox in details is modeled according to the practical structure. And the total wind energy generation system can be simulated well on the platform of AMESim.
In this paper, a 3 degree-of-freedom bearingless permanent magnet motor with axial active suspension is proposed. The structure and suspension principle of this novel bearingless permanent magnet motor are described in detail and its suspension mathematical models are constructed. Based on the mathematical models, a control system is designed for the new type bearingless permanent magnet motor. The...
