摘要： A system includes an encoding module and a decoding module. The encoding module generates a three-dimensional (3D) model of a part, modifies the 3D model to include a 3D structure, and generates a computer-aided design (CAD) file based on the modified 3D model. The decoding module determines whether the CAD file includes the 3D structure, authorizes operation of analysis software on the CAD file when the CAD file includes the 3D structure, and prohibits operation of the analysis software when the CAD file does not include the 3D structure.

摘要： A plurality of conductor bars are positioned within slots of a laminated electric steel disc stack, and the ends of the conductor bars are brazed to end rings to manufacture a rotor. The method includes inserting the conductor bars into the slots of the disc stack, providing the end rings with slots for receiving the ends of the conductor bars; positioning spacers of braze material adjacent each end of each of the conductor bars to create a gap between the end rings and the steel disc stack; and applying heat to melt the braze material of the spacers whereby braze material is furnished by the spacers of braze material to braze the first and second ends of the conductor bars to the first and second end rings. Channels are provided in the face of the end rings facing the steel disc stack to drain away excess braze material.

摘要： A method of providing solution heat treatment to an aluminum alloy. A non-isothermal process is used to provide a faster heat treatment cycle time while maintaining or further improving the alloy mechanical properties after subsequent aging hardening. The process includes establishing a temperature inside a processing vessel that is greater than a soaking temperature but less than a liquidus temperature of the alloy, rapidly heating the alloy to the soaking temperature in a first heating operation, reducing the temperature inside of the processing vessel to the soaking temperature, then heating the alloy to a temperature above the soaking temperature through a gradually increasing temperature in a second heating operation. Protocols for the improved solution heat treatment may be based on one or more of computational thermodynamics, dissolution kinetics and coarsening kinetics.

摘要： Methods of making 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. 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： 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.
