Mass Properties Identification of a Rigid Body Using Modal Analysis
In performing vibration analysis of the car engine on the engine support, it is necessary to know the mass properties of the engine including mass, position of the center of mass and mass inertia moments. Because the car engine has a relatively complex geometric shape and is composed of different components with different densities, determining its mass properties faces many challenges. There a...
متن کاملOutput-only Modal Analysis of a Beam Via Frequency Domain Decomposition Method Using Noisy Data
The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...
متن کاملAdaptive Modal Space Control of Flexible Structures: Theory
Adaptive control of a flexible continuous structure is investigated. The application is directed toward large sensor count and several actuator systems,(multiple input / multiple output (MIMO) control. Conventional large channel count control applications involve complicated techniques to determine the proper order of the model and the dominant modes to be controlled. Using spatial filtering to...
متن کاملImage Space Modal Analysis and Simulation of Object Motion
For the final project, I will work on improving my previous project on interactive dynamic video to combine and leverage advantages of different approaches. The interactive dynamic video is a research project from Abe Davis [Davis et al. 2015a], where they extracted image space modal bases from videos of vibrating objects, and used the knowledge to simulate interaction with the objects. The met...
متن کاملAn experimental investigation of a state-variable modal decomposition method for modal analysis
ABSTRACT This work presents the experimental evaluation of the state-variable modal decomposition (SVMD) method for modal parameter estimation of multi-degree-of-freedom and continuous vibration systems. Using output response ensembles only, the generalized eigenvalue problem is formed to estimate eigen frequencies and modal vectors for a lightly damped linear clamped-free thin experimental bea...
