Automated analysis technology for the transport superstructure heat transfer coefficient using a remote server
The main parameter determined in heat engineering tests of heat insulated cars superstructures or the locomotive operator’s cabs is the heat transfer coefficient К. The study introduces automated analysis technology for the heat transfer coefficient К of enclosure structures of the heat insulated transport means using a remote server. The underlying method provides coefficient K of the heat insulated transport means without additional work and time loss for complicated calculations. Personnel of test laboratories involved in heat engineering tests of vehicles possess tools for remotely calculating К, from any point in the world with internet access. To obtain К three controlled parameters measured during the heat engineering tests for 5.5 h including: the difference of the inside and outside temperature of the test object superstructure, total power of the electric heaters and geometric area of the heat transfer surface are sent to the server, after which the user promptly receives the calculated К. The economic effect of introducing the proposed technology for vehicle manufacture is the absence of required tests conducted at the test center; for an operating company - a significant reduction of the idle time of the vehicle at the test center directly affects the loss of profit. The proposed technology expands the area of operation of the test centers, while calculated К values are officially input into the data sheet of the vehicle.
