| titleOfInvention | Engine bench test temperature boundary control system, method and storage medium |
| abstract | The invention discloses a system and a method for controlling the temperature boundary of an engine bench test and a storage medium. The method comprises the following steps: establishing a rack temperature control equipment heat exchange model and an engine heat exchange demand prediction model; the engine heat exchange demand prediction model calculates the demand heat exchange quantity of the current working condition in real time according to the working condition of the engine, wherein the demand heat exchange quantity comprises the intercooling demand heat exchange quantity; the heat exchange model of the rack temperature control equipment calculates the heating amount and/or the cooling amount of the intercooled temperature controller according to the intercooled heat exchange amount required; calculating the heater power of the temperature controller after intercooling according to the heating amount, and calculating the heat exchange coefficient of a heat exchanger in the temperature controller after intercooling and variable control parameters influencing the heat exchange coefficient h according to the cooling amount, wherein the variable control parameters comprise the flow of a circulating pump and the opening of a three-way proportional valve; and controlling the after-intercooling temperature controller according to the control parameters calculated in the previous step so as to control the temperature boundary of the engine. The invention can lead the rack temperature control equipment to synchronously adjust the heat exchange quantity along with the working condition change of the engine. |
