Mechanical engineering services apply the principles of physics to the analysis, design, manufacturing, and maintenance of mechanical systems. They are staffed by professional mechanical engineers and other personnel who are trained in conceptual areas such as mechanics, kinematics, thermodynamics, fluid mechanics, machine design, and energy. Mechanical engineering services use their understanding of fundamental principles and knowledge gained through experience in many different ways. Typically, they analyze, design, manufacture and maintain products such as motor vehicles, aircraft, heating and cooling systems, combustion systems, watercraft, manufacturing plants, industrial equipment and machinery, fasteners, robotics, electromechanical systems, medical devices, and composite materials.
Selecting mechanical engineering services requires an understanding of the various services that are offered. Examples of these services include thermal design and analysis, combustion system design, HVAC design, and structural design and analysis. Thermal design and analysis services provide detailed thermal designs, develop and test thermal control systems, and apply their knowledge of thermal design concepts to aerospace applications. Combustion system design services may specialize in the design of diesel engines, automotive emissions reductions, or engine performance. HVAC design services are staffed by mechanical engineers and technicians who understand the requirements of heating, cooling and ventilation (HVAC) systems and equipment.
Mechanical engineering services design machinery, fasteners, composite structures, gears, motor vehicles, and refrigeration systems. Machine design services use computer aided design (CAD) applications to develop machinery and robotics. Fastener design services also use CAD software, but to design hardware such as bolts and screws. Composite structure design services specialize in the development of advanced composites and other engineered materials. Gear design services evaluate, specify, conceptualize, size, and draft gear designs. Motor vehicle design services provide expertise in areas such as motor vehicle engineering, engine design, and hybrid vehicles. Refrigeration design services are mechanical engineering services that develop chillers, freezers, and refrigerators.
Mechanical engineering services are staffed by professional engineers who belong to organizations such as the American Society of Mechanical Engineers (ASME) and the Society of Automotive Engineers (SAE). Individual mechanical engineers may also have expertise in fields such as aircraft design, solar design, refrigeration design, combustion system design, aerodynamic optimization, computational fluid dynamics (CFD), fluid flow design, and robotics. Mechanical engineering services that comply with European Union (EU) directives are also available.
