摘要： A method for forming a rotor for an induction motor includes providing a rotor core including a plurality of conductor bar grooves having first and second ends corresponding to first and second ends of the rotor core wherein the conductor bar grooves are progressively larger closer to the ends of the conductor bar grooves. The rotor core is placed into a casting mold, and molten metal is introduced into a first end of the casting mold. The molten metal flows from the first end of the casting mold through the plurality of conductor bar grooves to a second end of the casting mold. The molten metal solidifies to form conductor bars in the plurality of conductor bar grooves and to form shorting rings across exterior portions of the end elements within the first and second ends of the casting mold.

摘要： A method and system for optimizing a simulated casting of a light weight alloy component. The simulation includes passing component design data through various computational modules relating to casting designs, process modeling and optimization, material microstructure and defects and product performance. Variations in microstructure and defects across various very small size scales are extended to increasingly larger scales to permit structural performance calculations of the cast component to take such non-uniformities into consideration. At least some of the modules employ an expert system-based approach to achieve the optimized results. The results can be compared to end user needs to determine if redesign of the part geometry or manufacturing process is needed.

摘要： Squirrel cage rotors of aluminum based material end rings joined with high conductive and durable material (such as copper) conductor bars for use in electric motors and methods of making them are described. The methods include forming conductor bars by casting or other metal forming methods in the slots of laminate steel stack, or positioning the preformed or premade solid conductor bars in the longitudinal slots of the stacked laminated steel, with bar ends extending out of the laminated steel stack ends, optionally coating the extended part of the conductors (bars) with a latent exoergic coating containing Al and one or more conductor bar chemical elements, positioning the laminated steel stack having conductors (bars) in a casting mold that forms the cavity of both end rings of the rotor, filling the end ring cavities with aluminum melt, and allowing the end rings to solidify under pressure. Alternatively, the conductor bars and end rings can be made separately and mechanically joined together.

摘要： Computational systems, methods, and articles of manufacture to predict at least one of residual stresses and distortion in quenched aluminum castings. Residual stresses and distortion may be predicted through incorporating thermal strains induced during quenching with the nonlinear constitutive behavior of quenched microstructures of a quenched aluminum casting, wherein thermal strains arise generally from non-uniform transient temperature distribution of the casting during quenching. The transient temperature distribution of the aluminum casting during quenching may be calculated based on heat transfer coefficients specific to one or more nodes, elements and/or zones on the surfaces of the aluminum casting. The nonlinear constitutive behavior of the quenched aluminum casting may be modeled as functions of temperatures, strain rates, and microstructure variations. A material constitutive model accounts for not only strain hardening and creep, but also precipitate hardening. Thereby, residual stresses and distortion in the quenched aluminum castings can be predicted using the embodiments.

摘要： A system for evaluating a manufacturability of a casting design. The system includes at least one of a geometry analyzer, a casting evaluation tool, a residual stress evaluation tool, and a machining evaluation tool. The geometry analyzer analyzes a geometric design of the casting design to determine its geometric design-ability, the casting evaluation tool evaluates the casting design to determine its cast-ability, the residual stress evaluation tool evaluates the casting design to determine its heat treat-ability, and the machining evaluation tool evaluates the casting design to determine a machine-ability of the casting design. If the casting design is determined as not geometrically design-able, not cast-able, not heat treat-able, or not machine-able by the geometry analyzer, the casting evaluation tool, the residual stress evaluation tool, or the machining evaluation tool, respectively, then modifications to the casting design are recommended to optimize the casting design for manufacturing.

摘要： A fuel quality monitoring system includes a fuel composition sensor configured to provide an indication of a composition of a liquid fuel within a fuel tank, and a controller. The controller is configured to receive the indication of the monitored fuel composition from the fuel composition sensor; detect an amount of an impurity from the received indication; and compare the amount of the impurity to a threshold. If the amount of the impurity exceeds the threshold, the controller is configured to adjust an operating parameter of an engine to account for the detected impurity. When the amount of the impurity exceeds a threshold which makes engine combustion unmanageable, the fuel is restricted from entering the engine or fuel tank.
