| dc.description.abstract | This report is the final documentation for the Powered Harrow Wheel that our team has been designing for Elmer’s Manufacturing. Elmer’s Manufacturing is currently undergoing a major overhaul on their current flagship product the Super7 Harrow within their engineering department and has approached the University of Manitoba to assist with the Harrow Wing wheel redesign. Elmer’s Manufacturing is currently having problems with their existing Harrow wing wheel system due to a lack of operator convenience, a high number of redundant parts, and performance issues with their existing wheel system. Elmer’s Manufacturing is hoping the design team is able to design a single pivoting and optionally powered wheel system to replace the current two-wheel system design. During the initial phase of the design, the team has developed a list of customer needs and specifications metrics to avoid scope creep during the design phase. A house of quality was developed to capture the relevance and the importance between the customer needs and specification metrics. This information would help the team during the concept generation and selection phase due to the establishment of a clear priority. From the information gathered during the initial phase, the team has determined 4 critical motion components to develop in order to assembly the wheel system. The motion components are mode transition motion, power transmission method, power steering motion, and power drive module. During the concept selection section phase, the team has come up with 48 ideas for mode transition motion, 5 possible power transmission concepts, 2 options for power steering motion, and 2 options for power drive modules. The team then evaluated those concepts through a combination of customer feedback and an extensive weighted screening process. By the end of the process, the team has chosen a bicycle like wheel frame for mode transition motion, a chain and sprocket for power transmission method, a hydraulic motor for power drive module, and a hydraulic cylinder for power steering motion. In the final design section, the team used various analytical methods such as MATLAB, Excel coding, Finite Element Analysis, and hand engineering calculations to determine the safety and satisfaction of design requirements for each individual module on the wheel design. All wheel modules must pass a minimum factor of safety 2 and be able to provide 2.0G fatigue impact resistance with occasional 2.5G shock resistance. A CAD model and assembly drawings of the Wheel system is made for both powered and nonpowered wheel option. Comparing our final design to the original design metrics, the team has met almost all metrics. The following points will show a summary of the critical achievement of the wheel design: - The wheel system is now able to replace the existing two wheels - The wheel system would provide more operator convenience due to fully automated wheels - The wheel system design is adaptable for all three Harrow sizes - The Power drive of the wheel system can be optional and able to be sold separately - The wheel system has a service life longer than 4 years The cost of the system would estimate to be $4686.62 dollars for a pair of wheels without the power option, and both power modules would estimate to cost $3205.14 per pair. The report content would contain all aspects of decisions made and deep analytical analysis for each design component of the wheel design. | en_US |
