ATM(Automated-feller Machine) is a machine that receives and pays money directly. The double bill detector (DBD) module of an ATM detects double bill from its thickness. In this paper, the dynamic behavior of the DBD was analyzed numerically and experimentally. The moment of inertia of the double bill lever and the spring constant were measured respectively. And the displacements of the ]ever was measured experimentally. The measured dynamic behaviors were simulated numerically using vector equation. Through the analysis, the design factors were found to make a fast and reliable new ATM machine.

ATM(Automated-Teller Machine) is a maching that receives and pays money directly. The gate module of an ATM separates forgeries from bills and changes the transfer direction of bills. In this paper, the dynamic behavior of the gate was analyzed numerically and experimentally. The moment of inertia of the gate lever, the suction force of the solenoid and the spring force were measured respectively. And the displacements of the plunger, the vibration of the bracket, the input voltage and current were measured experimentally. The measured dynamic behaviors were simulated numerically using SAMCEF program, which can accommodate the kinematics and vibrations of flexible bodies. Through the analysis, the design factors were found to make a fast and reliable new ATM machine.
