Free and forced vibration analysis on finite element model of an off-road vehicle
In the present paper, the modal analysis on a full finite element model of an off-road vehicle. This vehicle was modeled in the CATIA software and then meshed in the HYPERMESH software. The free vibration analysis was conducted by the ABAQUS software. By applying an external displacement, the forced vibration analysis was also performed. As a result, natural frequencies and shape modes were ext...
متن کاملLinear Parameter-varying Control for Active Vibration Isolation Systems with Stiffness Hysteresis
We consider the use of linear parameter-varying methods for the control of stiffness hysteresis in vibration isolation systems. We assume that the hysteresis model is known, and we describe it using a stiffness parameter that takes values in a compact convex set. The proposed parameter-dependent controller is continuously scheduled based on real-time measurements or estimates of the stiffness, ...
متن کاملAdaptive Control for a Microgravity Vibration Isolation System
Most active vibration isolation systems that try to a provide quiescent acceleration environment for space-science experiments have utilized linear design methods. In this paper, we address adaptive control augmentation of an existing classical controller that combines a high-gain acceleration inner-loop feedback together with a low-gain position outer-loop feedback to regulate the platform abo...

متن کاملFrom Forced Vibration Testing
THE TECHNIQUE OF DETERMINATION OF STRUCTURAL PARAMETERS FROM FORCED VIBRATION TESTING Wai Fan Tsang This thesis details the results of an investigation into a technique for determination of "useful" structural parameters from forced vibration testing. The implementation of this technique to full scale civil engineering structures was achieved by several developments in the experimental and comp...
