DEVICE AND A METHOD FOR ANALYZING AIR PRESSURE PATTERNS OF A DOOR ENGINE OF AN ELECTRIC RAIL CAR ENABLING AN ANALYSIS OF THE INNER AIR PRESSURE PATTERNS OF THE DOOR ENGINE AND A COMPONENT TEST OF THE DOOR ENGINE

摘要

PURPOSE: A device and a method for analyzing air pressure patterns of a door engine of an electric rail car is provided to analyze air pressure patterns of the door engine of the electric rail car, thereby precisely performing an operation test of the door engine.;CONSTITUTION: A device for analyzing air pressure patterns of a door engine of an electric rail car includes an air pressure input/output unit (10), a measuring unit (20), and a door engine testing unit (30). The air pressure input/output unit includes a solenoid (11), a head component (13), and a jig (12). The solenoid supplies air pressure input/output power, and the air pressure input/output power is inputted and outputted by the head component. The jig checks a change in the air pressure of the head component. The measuring unit measures the air pressure of the air pressure input/output unit. The door engine testing unit analyzes air pressure change patterns inside the door engine measured by the measuring unit and displays the result with a graph.;COPYRIGHT KIPO 2013;[Reference numerals] (11) Solenoid valve; (12) Jig; (13) Head component (exhaust); (31) PCL unit (power ON/OFF); (32) Computer unit (diagnosis S/W); (AA) Digital air pressure measuring unit
