Abstract: PURPOSE: A rod-arm type dynamic characteristic testing device for a suspension, a testing method, and a dynamic characteristic testing system are provided to accurately perform a dynamic characteristic test of a suspension for high-weight material with a structure minimizing friction under an environment similar to an actual vehicle condition. CONSTITUTION: A rod-arm type dynamic characteristic testing device for a suspension includes a body, a rod arm, an excitation plate (120), a connection bar, an actuator (130), a displacement sensor, a joining unit, and a plurality of rods. The body is joined to a fixed structure and includes an acceleration sensor. An end portion of the rod arm is joined to the body, and a rod wheel (102) is formed on the other end portion thereof. The excitation plate is arranged to be in contact with the rod wheel. The connection bar is connected to the excitation plate so that the excitation plate is freely vibrated as a free end. The excitation plate forms a 4-joint link structure connecting the fixed structure and the excitation plate each other, thereby controlling the excitation plate to be moved vertically. The actuator excites the excitation plate. The displacement sensor measures the relative displacement of the body with respect to the fixed structure.

Abstract: PURPOSE: A circuit for controlling a discharge of a high-voltage DC(Direct Current) power supplier is provided to improve the control property by adding a discharge circuit to an output terminal of a flyback converter to discharge rapidly a voltage stored in a capacitor. CONSTITUTION: A transformer(T1) is driven by a MOS transistor(M1) which is a switching device to convert an input voltage(Vs) into a predetermined level of a high voltage and output it. A diode(D1) and a capacitor(C1) rectify and smooth the high voltage outputted from the transformer(T1) to supply it to an ER(Electro-Rheological) fluid application equipment. When an output voltage(Vo) of the capacitor(C1) drops, a discharge circuit(2) discharges rapidly the output voltage(Vo) by force. A controller(4) controls a turn-on operation of the MOS transistor(M1) based on an error component of the output voltage outputted from a subtractor(3) and outputs a control signal for driving the discharge circuit(2) at every time when reaching to a discharge period.
