Title: OPTIMIZATION AND EXPERIMENTAL VALIDATION OF ELECTROSTATIC ADHESIVES

Show moreElectrostatic adhesion provides an attachment mechanism for robotic grippers that is both controllable and e ective over a wide range of surfaces including conduc- tive, semi-conductive and insulating materials. The adhesives function by utilizing a set of high voltage electrodes that generate an electric eld. This electric eld polarizes the substrate material, thus generating an adhesion force. Optimizing the geometry of these conductive electrodes provides enhanced adhesion forces that in- creases attachment robustness. Previous researchers have attempted to increase the adhesion level of an electrostatic adhesive but no e ort has been made to optimize the geometry and con guration of the electrodes. This thesis presents a method to increase the adhesion level of electrostatic adhesives by optimizing the electrode geo- metric parameters: width of the electrodes, thickness of the electrodes, gap between the electrodes and number of electrodes. With the optimized electrode geometry, an improvement of up to 500 percent in shear stress is achieved compared to previously published values.

Title: UNMANNED AIRCRAFT SYSTEM SENSE AND AVOID INTEGRITY AND CONTINUITY

Show moreThis thesis describes new methods to guarantee safety of sense and avoid (SAA) functions for Unmanned Aircraft Systems (UAS) by evaluating integrity and continuity risks. Previous SAA e↵orts focused on relative safety metrics, such as risk ratios, comparing the risk of using an SAA system versus not using it. The methods in this thesis evaluate integrity and continuity risks as absolute measures of safety, as is the established practice in commercial aircraft terminal area navigation applications. The main contribution of this thesis is a derivation of a new method, based on a standard intruder relative constant velocity assumption, that uses hazard state estimates and estimate error covariances to establish (1) the integrity risk of the SAA system not detecting imminent loss of “well clear,” which is the time and distance required to maintain safe separation from intruder aircraft, and (2) the probability of false alert, the continuity risk. Another contribution is applying these integrity and continuity risk evaluation methods to set quantifiable and certifiable safety requirements on sensors. A sensitivity analysis uses this methodology to evaluate the impact of sensor errors on integrity and continuity risks. The penultimate contribution is an integrity and continuity risk evaluation where the estimation model is refined to address realistic intruder relative linear accelerations, which goes beyond the current constant velocity standard. The final contribution is an integrity and continuity risk evaluation addressing multiple intruders. This evaluation is a new innovation-based method to determine the risk of mis-associating intruder measurements. A mis-association occurs when the SAA system incorrectly associates a measurement to the wrong intruder, causing large errors in the estimated intruder trajectories. The new methods described in this thesis can help ensure safe encounters between aircraft and enable SAA sensor certification for UAS integration into the National Airspace System.

Show moreA chromium vanadium steel is characterized for use in a hex wrench hand tool application. The application justi es the need for a high strength and ductile steel. The standard steel alloy used for hex wrenches is 8650. An alternative lower cost steel alloy, 61B60CrV, is considered for the hex wrench hand tool application. The microstructure achieved is tempered martensite. First martensite is formed to create a high strength but brittle material. Then the martensite is reheated and tem- pered to improve the ductility of the material. Both 8650 and 61B60CrV alloys are thermally processed in the same way to create the tempered martensitic structure. The mechanical properties of the proposed steel is evaluated and compared to that of the standard 8650 steel alloy. The 61B60CrV alloy evaluation includes torsion test- ing, hardness and hardenability measurements, and grain size determination. The 61B60CrV alloy is proven to meet the hex wrench hand tool mechanical requirements with a tempered martensitic microstructure. During Jominy hardness testing of the 61B60CrV alloy, it is determined that the hardness requirements are met for a wide range of microstructures. Samples of the 61B60CrV alloy are austempered for di er- ent durations then quenched to room temperature to create samples with di erent amounts of mixed microstructures of bainite and martensite. A range of mixed mi- crostructures are shown to meet the strength, ductility, and hardness requirements for the hex wrench hand tool application without tempering.

Show moreOpen die forging technique is mainly used to achieve desired product shape and refine the product mechanical quality. Large ingots tend to have internal defects such as shrinkage cavities and porosity, which have to be closed during the primary forging stage to ensure sound internal quality of forged parts. In this work, the finite element method was used to simulate the open die forging process, varying different process parameters that affect the void closure behavior profoundly. Numerical models were constructed in FORGE 2011® using practical forging parameters and material rheological data obtained experimentally from Gleeble compression tests. Forging variables including die design, operational practice and boundary conditions were studied thoroughly. Parameters such as die width, die geometry, die overlap, reduction amount per pass were studied with intense attention paid on the specific mechanical properties of H13 steel, so that this study can be applied to solve real world problems. Also, the temperature gradient and friction condition between billet and die were investigated. Physical experiment validation was carried out with a miniature billet sample. The experiment results were compared with the simulations, showing there was good agreement between the two, giving confidence to the simulation results. Based on the simulation results the optimum forging parameters were proposed to ensure full closure of internal defects.

Show moreWhile vertical-axis wind turbines (VAWTs) have a simpler design than the horizontal-axis wind turbines, their development has been hindered due to their unsteady aerodynamics and complex flow field. In this thesis, a parameterized study is conducted to simulate a baseline VAWT using STAR-CCM+, a commercial finite volume code. A hybrid grid scheme, with structured prism layer mesh at the surface of the blades, is used to properly resolve the turbulent boundary layers on the blades. The flow was highly unsteady due to the rotating geometries. Thus, a sliding mesh technique is implemented at the interface of rotating and stationary zones. The dominant factors limiting the performance of the VAWTs are investigated for a range of moderate tip speed ratios, by visualizing the flow field and modeling the individual blade aerodynamics. The VAWT aerodynamics is shown to be dominated by the dynamic stall, at low tip speed ratios, and by the blade-wake interactions and the wake blockage effects, at high tip speed ratios. The concept of turbine coupling is used to improve the performance of the VAWTs by their internal aerodynamic interactions. Two counter-rotating turbines are placed in close proximity, and simulated over the same range of tip speed ratios as before, and for a set of different spacing between them. The effects of spacing and the tip speed ratio on their overall power output and their wake recovery characteristics are then investigated. A cluster of turbines with spacing equal to 1.50 turbine diameters and tip speed ratio of three is shown to have the quickest wake recovery and highest power enhancement, increasing the turbine average power coefficient by 22%.
