This article presents the reduction of vibration generated by an automobile fuel pump. In order to analyze the vibration of the fuel pump, a simplified dynamic model is established, which is composed of a rigid rotor and a equivalent springs. The equivalent stiffnesses of the upper and lower assemblies are evaluated by the comparison of modal testing results and the finite element analysis.

It takes considerable time to generate accurate clutter signal using conventional clutter generation scheme. In this paper, real-time schemes are proposed, which have reasonable accuracy and are applicable to testing the radar performance. Proposed methods are compared through the simulation, which represented that clutter signal can be generated in real-time when using proposed methods for simulated signal generator.
