A Multi-view Optical Technique to Extract the Operating Deflection Shapes of a Full Vehicle Using Digital Image Correlation
No full textThe automotive and aerospace industries are increasingly using light-weight material to improve vehicle performance while reducing fuel consumption. However, using light-weight material can increase the air-borne and structure-borne noise. Thus, special attention needs to be paid in designing the vehicle body structure and evaluating its dynamics. In order to accomplish this, modal analysis is conventionally used. In this technique, the structure is excited using an impulse hammer or a mechanical shaker, and the response is measured using accelerometers. However, using contact-based transducers can mass-load the structure and can only provide data at a few discrete points. In the last decade, stereo-photogrammetry and three-dimensional digital-image correlation have received special attention in collecting operating data for structural analysis. These non-contact optical techniques provide a wealth of distributed data over the entire structure. However, the stereo-camera system is limited by the field of views of the cameras and can only measure the response on the parts of a structure for which cameras have lines of sight. Therefore, a single pair of DIC cameras may not be able to provide deformation data for an entire structure. A multi-view 3D DIC approach, however, can be used to predict the vibrational characteristics of a full vehicle. A pair of DIC cameras is passed over the entire vehicle to capture the deformation data of each field of view. The measured data includes the geometry and displacement data, which is mapped into a global coordinate system using 3D transformation matrices. The obtained data in the time domain for each field of view is transformed to the frequency domain using a Fast Fourier Transformation (FFT) to extract the operational deflection shapes and resonant frequencies for each field of view. The obtained deflection shapes are scaled and stitched in the frequency domain to extract the operating deflection shapes of the entire vehicle
Study of Metallic Thin Films on Epoxy Matrix as Protective Barrier to Ultraviolet Radiation
No full textEpoxy based composites are widely being used in aviation, automotive and construction industries due to their high strength and stiffness to weight ratios and good electrochemical corrosion resistance properties. During their exposure to harsh environmental conditions such as ultraviolet (UV) radiation and high temperature, the epoxy matrix suffers significant degradation leading to detrimental effects on the mechanical properties of the entire composite. In this study the benefits of application of thin metallic films that can act as protective barriers to UV radiation\u27s damaging effects on the epoxy are evaluated. Aluminum, copper, titanium and zirconium coatings are deposited on the epoxy substrates using high vacuum DC magnetron sputtering technique. All metallic coatings provided protection to the epoxy substrate exposed to UV radiation where the aluminum offered the highest and zirconium the least amount of protection
Impedance Analysis fo Thin YSZ Electrolyte for Low-temperature Solid Oxide Fuel Cells
No full textSolid oxide fuel cells based on yttria-stabilized zirconia materials have demonstrated a higher level of technology maturity compared to newer materials actively researched to lower the operating temperature. Yttria-stabilized zirconia-based cells can operate around 600 °C and achieve competitive power densities provided the electrolyte can be fabricated relatively thin. In this work, a 2.5-μm thick yttria-stabilized zirconia electrolyte, commercially available, anode-supported solid oxide fuel cell is systematically investigated under various electrochemical conditions, and area of improvements with the electrochemical performance are identified. The cell consists of a Ni-YSZ bulk and functional layer anode, YSZ electrolyte, GDC barrier layer, and LSCF cathode. Using humidified hydrogen, the peak power densities are determined to be 0.31, 0.58, 0.96, 1.41, and 1.78 W/cm2 at 600, 650, 700, 750, and 800 °C, respectively. It is found that the ceria barrier layer is porous; thus, it is not effective to avoid the formation of strontium zirconate. It is therefore expected that the performance can be improved further if a denser ceria barrier layer can be deposited. In addition, energy dispersive spectroscopy analysis revealed significant Ce/Zr interdiffusion between the barrier layer and the electrolyte

8/28/2019: Course Change Form MECH 528
No full textKettering University is eliminating 500 course numbers due to HLC concerns about our graduate program. Since our 500 level courses are defined as mezzanine they are not considered to be graduate courses by HLC. This puts a limit on how many 500 level courses a graduate student can take in the graduate program. According to HLC they cannot take more than five 500 courses. The Course Number is being changed to MECH-428 and the Course Description is being corrected. Prerequisites are updated so only seniors can take the course
