Mechanical Design And Manufacturing Of Electric...
Technology itself has also shaped how mechanical engineers work and the suite of tools has grown quite powerful in recent decades. Computer-aided engineering (CAE) is an umbrella term that covers everything from typical CAD techniques to computer-aided manufacturing to computer-aided engineering, involving finite element analysis (FEA) and computational fluid dynamics (CFD). These tools and others have further broadened the horizons of mechanical engineering.
Mechanical Design and Manufacturing of Electric...
Manufacturing is an important step in mechanical engineering. Within the field, researchers investigate the best processes to make manufacturing more efficient. Laboratory methods focus on improving how to measure both thermal and mechanical engineering products and processes. Likewise, machine design develops equipment-scale processes while electrical engineering focuses on circuitry. All this equipment produces vibrations, another field of mechanical engineering, in which researchers study how to predict and control vibrations.
Engineering economics makes mechanical designs relevant and usable in the real world by estimating manufacturing and life cycle costs of materials, designs, and other engineered products.
Nanotechnology allows for the engineering of materials on the smallest of scales. With the ability to design and manufacture down to the elemental level, the possibilities for objects grows immensely. Composites are another area where the manipulation of materials allows for new manufacturing opportunities. By combining materials with different characteristics in innovative ways, the best of each material can be employed and new solutions found. CFD gives mechanical engineers the opportunity to study complex fluid flows analyzed with algorithms. This allows for the modeling of situations that would previously have been impossible. Acoustical engineering examines vibration and sound, providing the opportunity to reduce noise in devices and increase efficiency in everything from biotechnology to architecture.
Get ready to contribute on the job from day one. Our students benefit from hands-on experiences ranging from our senior capstone design program to our enterprise teams to internships/co-ops. As a mechanical engineer, you can make a difference in the world by using the latest technologies to help solve today's grand challenges.
Like other engineers, mechanical engineers use computers extensively. Mechanical engineers are routinely responsible for the integration of sensors, controllers, and machinery. Computer technology helps mechanical engineers create and analyze designs, run simulations and test how a machine is likely to work, interact with connected systems, and generate specifications for parts.
Mechanical engineers typically need a bachelor's degree in mechanical engineering or mechanical engineering technologies. Mechanical engineering programs usually include courses in mathematics and life and physical sciences, as well as engineering and design. Mechanical engineering technology programs focus less on theory and more on the practical application of engineering principles. They may emphasize internships and co-ops to prepare students for work in industry.
As manufacturing processes incorporate more complex automation machinery, mechanical engineers are expected to be needed to help plan for and design this equipment. However, employment declines in some industries may temper overall employment growth of mechanical engineers.
Complete designs faster and with higher quality by enabling electrical engineers to work collaboratively with their mechanical and software engineering peers, saving time and eliminating errors during industrial electrical design.
This work presents a finite element analysis-based, topology optimization (TO) methodology for the combined magnetostatic and structural design of electrical machine cores. Our methodology uses the Bi-directional Evolutionary Structural Optimization (BESO) heuristics to remove inefficient elements from a meshed model based on elemental energies. The algorithm improves the average torque density while maintaining structural integrity. To the best of our knowledge, this work represents the first effort to address the structural-magnetostatic problem of electrical machine design using a free-form approach. Using a surface-mounted permanent magnet motor (PMM) as a case study, the methodology is first tested on linear and nonlinear two-dimensional problems whereby it is shown that the rapid convergence achieved makes the algorithm suitable for real-world applications. The proposed optimization scheme can be easily extended to three dimensions, and we propose that the resulting designs are suitable for manufacturing using selective laser melting, a 3D printing technology capable of producing fully dense high-silicon steel components with good soft magnetic properties. Three-dimensional TO results show that the weight of a PMM rotor can be slashed by 50% without affecting its rated torque profile when the actual magnetic permeability of the 3D-printed material is considered.
There are numerous differences in how EVs are manufactured when compared to ICE vehicles. The focus used to be on protecting the engine, but this focus has now shifted to protecting the batteries in manufacturing an EV. Automotive designers and engineers are completely rethinking the design of EVs, as well as creating new production and assembly methods to build them. They are now designing an EV from the ground up with heavy consideration to aerodynamics, weight and other energy efficiencies.
Using this approach, the mechanical design team sent their design models to the electrical team, which amended the designs and returned them to the mechanical team. These iterative design exchanges continued over weeks and months, resulting in huge design and prototyping costs and product launch delays. The information silos and barriers between systems made it difficult for eNovates to fit electrical designs into mechanical spaces. They also created problems in communicating design information to contract manufacturers. eNovates was sending confusing and disconnected details of the design for manufacturing, which resulted in issues with requirements and regulations.
With its previous software solutions, eNovates could deliver a 3D file depicting the mechanical design, electrical drawings, and three separate bills of materials (BOMs) for drawing mechanical, electrical and PCB content. However, the information was not well integrated, and its delivery was not efficient.
Solid Edge Technical Publishing software offered eNovates a superior solution for preparing information for manufacturing. Now, the manufacturing package includes a unified BOM for the entire product, which is especially useful for pricing. For PCB manufacturing, a standard format file produced using PADS Professional software includes information about each physical board layer and coordinates for PCB objects like copper traces, vias, pads and solder masks. For electrical manufacturing, Solid Edge Technical Publishing software extracts the list of cables and their locations, connections, cut lengths, and torques required on their connecting screws, all produced using the Solid Edge electrical design software. With the Solid Edge 3D model, the publishing software fully and visually describes each step in the product assembly and testing processes.
Solid Edge technical publishing has helped eNovates improve the clarity, accuracy and completeness of manufacturing information in comprehensive case files. The integration of PADS Professional with Solid Edge has helped improved communication between PCB designers and mechanical engineers.
Certain engineering disciplines, however, are often grouped together because they work in harmony. A case in point is mechanical vs. electrical engineering. Both professions are highly rewarding and entail investigation, analysis, and design of equipment and devices, but one is slightly broader in scope than the other.
A significant amount of overlap exists between mechanical engineering and electrical engineering. As such, many of those who specialize in either discipline may work for the same types of organizations, such as semiconductor manufacturers, navigation systems designers, or utility service providers.
The program offers several specializations, including mechanical engineering and electrical engineering, among others. Whichever specialization you select, your coursework will include these core courses. Each class is custom designed to supply you with the intellectual and practical skills you need to succeed in the vast field of engineering.
Electrical engineers design, develop, test and manage the manufacturing of electrical equipment, from electric motors and navigation systems to power generation equipment and the electrical components of vehicles and personal devices.
This is a very broad subject, which overlaps with lots of other types of engineering. However, the most common specializations of mechanical engineering include manufacturing, transportation systems, combustion, nanotechnology and robotics. Mechatronics engineering may also be of interest; this combines mechanical and electronic engineering with areas such as computer and control engineering. Read more here.
