The current design process of the two automotive air conditioning devices (condenser and evaporator) mainly use a large number of experiments which are very time-consuming. In view of this flaw, this paper presents a structurized procedure to develop the simulation platform of the two devices. Firstly, the physical and mathematical models of the two devices were established. The heat transfer situation...
This paper discusses and analyses precise hydraulic pressure control of VVVF hydraulic system. The mathematical model of system is established and PID control law is adopted. Numerical simulation of PID controller is carried out with the SIMULINK of MATLAB. In the non-linear, time-varying VVVF hydraulic system, however, conventional PID control often cannot satisfy the request of precise pressure...
An intelligentized, comprehensive and high efficiency test system of solenoid valve for oil medium is designed in this paper, aiming to the disadvantage of current test devices in most solenoid valve factories in China. Serial communication of OPC-SERVER, sequential control of PLC, frequency conversion speed regulation technology and data acquisitions by LabVIEW are all achieved in this system; modeling...
