Mechanical engineers use thermo-science to design engines and power plants , heating, ventilation, and air-conditioning HVAC systems, heat exchangers , heat sinks , radiators , refrigeration , insulation , and others. A technical drawing can be a computer model or hand-drawn schematic showing all the dimensions necessary to manufacture a part, as well as assembly notes, a list of required materials, and other pertinent information.
Drafting has historically been a two-dimensional process, but computer-aided design CAD programs now allow the designer to create in three dimensions. Optionally, an engineer may also manually manufacture a part using the technical drawings. However, with the advent of computer numerically controlled CNC manufacturing, parts can now be fabricated without the need for constant technician input.
Manually manufactured parts generally consist spray coatings , surface finishes, and other processes that cannot economically or practically be done by a machine. Drafting is used in nearly every subdiscipline of mechanical engineering, and by many other branches of engineering and architecture. Modern tools[ edit ] An oblique view of a four-cylinder inline crankshaft with pistons Many mechanical engineering companies, especially those in industrialized nations, have begun to incorporate computer-aided engineering CAE programs into their existing design and analysis processes, including 2D and 3D solid modeling computer-aided design CAD.
This method has many benefits, including easier and more exhaustive visualization of products, the ability to create virtual assemblies of parts, and the ease of use in designing mating interfaces and tolerances. Other CAE programs commonly used by mechanical engineers include product lifecycle management PLM tools and analysis tools used to perform complex simulations.
Analysis tools may be used to predict product response to expected loads, including fatigue life and manufacturability. Using CAE programs, a mechanical design team can quickly and cheaply iterate the design process to develop a product that better meets cost, performance, and other constraints.
No physical prototype need be created until the design nears completion, allowing hundreds or thousands of designs to be evaluated, instead of a relative few. In addition, CAE analysis programs can model complicated physical phenomena which cannot be solved by hand, such as viscoelasticity, complex contact between mating parts, or non-Newtonian flows.
As mechanical engineering begins to merge with other disciplines, as seen in mechatronics , multidisciplinary design optimization MDO is being used with other CAE programs to automate and improve the iterative design process.
MDO tools wrap around existing CAE processes, allowing product evaluation to continue even after the analyst goes home for the day. They also utilize sophisticated optimization algorithms to more intelligently explore possible designs, often finding better, innovative solutions to difficult multidisciplinary design problems.
GATE Class Notes – Mechanical Engineering
Areas of research[ edit ] Mechanical engineers are constantly pushing the boundaries of what is physically possible in order to produce safer, cheaper, and more efficient machines and mechanical systems. Some technologies at the cutting edge of mechanical engineering are listed below see also exploratory engineering.
Micro electro-mechanical systems MEMS [ edit ] Micron-scale mechanical components such as springs, gears, fluidic and heat transfer devices are fabricated from a variety of substrate materials such as silicon, glass and polymers like SU8. Examples of MEMS components are the accelerometers that are used as car airbag sensors, modern cell phones, gyroscopes for precise positioning and microfluidic devices used in biomedical applications.
