To study the influence of random vibration on fatigue life airborne equipment, an aircraft electrical control box was selected as research object. First, finite element software used to model dynamics investigate its mode frequencies. The accuracy simulations verified by performing experiments. Second, superposition method analyze flight direction (X axis), side (Y and altitude (Z axis) respons...

Hydraulic brakes in automobiles play a vital role for the safety on the road; therefore vital components in the brake system should be monitored through condition monitoring techniques. Condition monitoring of brake components can be carried out by using the vibration characteristics. The vibration signals for the different fault conditions of the brake were acquired from the fabricated hydraul...

A comparative study of vibration and acoustic noise reductions via electronic switching controls for switched reluctance motor (SRM) is presented. First, studies concerning the acoustic noise and vibration sources, their effects and the existing mitigation approaches are given. Then five switching control approaches, which belong to the magnetic and electronic remedies, are proposed and applied...
