Mechanical engineering might seem a bit boring and old fashioned in the days when “software runs the world”. Yet consider the story of GrabCad. GrabCAD is a CAD-sharing marketplace that liaisons between manufacturers and CAD engineers. In 2012 the GrabCAD network included about 70,000 mechanical engineers when the startup raised $4 mln of venture capital. Couple of years later GrabCad was acquired for $100 Mln.

According to Bureau of Labor Statistics there are 270,700 mechanical engineers in USA with average annual salary of about $87,000.

What do the Mechanical Engineers do?

Mechanical engineers work with other team members to create new product designs that meet customer needs and relevant government codes and regulations. They create these designs using established engineering practices and relevant technological tools. They research designs and make recommendations based on appearance, safety, budget, and function, and estimate the time and cost needed to complete projects.

Mechanical engineers analyze, research, design, develop, manufacture, and test tools, engines, machines and mechanisms. Mechanical engineering comprises design of power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines; as well as design of power-using machines such as refrigeration and air-conditioning equipment, machine tools, material-handling systems, elevators and escalators, industrial production equipment, and robotics.

Precision engineering is a subdiscipline of mechanical engineering dealing with designing machines, mechanism and mechanical parts that have exceptionally low tolerances, are repeatable, and are stable over time. Precision engineering has applications in machine tools, MEMS, NEMS, optoelectronics design, and many other fields.

Mechanical engineers support manufacturing, maintenance, or technical sales. Mechanical engineering education is often a must for managers marketing mechanical equipment. Mechanical engineering is one of the major and broadest engineering fields incorporating the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems.Mechanical engineers design tools used in other fields.

Mechanical engineers begin by analyzing users’ needs, and then design, test, and develop machines and mechanisms to meet those needs. During this process they create drafts, diagrams, flowcharts and other documentation, and may also create the operation and maintenance manuals.

Mechanical engineers learn basic disciplines such as chemistry, physics, and specialised engineering courses such as chemical engineering, civil engineering, and electrical engineering.
Most mechanical engineering programs include calculus, differential equations, partial differential equations, linear algebra, abstract algebra, and differential geometry, among others.
In addition to the core mechanical engineering curriculum, many mechanical engineering programs offer more specialized programs and classes, such as robotics, precise mechanics, transport and logistics, cryogenics, fuel technology, automotive engineering, biomechanics, vibration and optics.

Computer-Aided Design (CAD)

Today mechanical engineers are expected to know computer-aided engineering (CAE) programs and use them for design and analysis of mechanical systems, including 2D and 3D solid modeling computer-aided design (CAD). CAD increases productivity of machine designer and provides better visualization of products, the ability to create virtual assemblies of parts, and the ease of use in designing mating interfaces and tolerances.

Stirling Engine Workshop, August 22 – 25, 2011, London, UK

August, 1 2011 – The Stirling Engine Workshop will be held August 22-25, 2011, London, UK. There is a lot of recent interest in the use of the Stirling engine due to its high efficiency. Stirling-cycle engines were invented in the beginning of 19th century and were commonly used until arrival of Otto cycle engine. Stirling engines are external combustion engines designed as sealed systems with an inert working fluid, usually either helium or hydrogen.
Precision engineering
The workshop addresses technical challenges that have delayed adoption of Stirling engine technology:

  • Low-leakage piston rings and bearings for operation in the unlubricated working engine space
  • Long-term durability/reliability and high cost
  • Shaft seals to separate the high pressure hydrogen space from the lubrication in the mechanical drive train
  • Minimization of material stress and corrosion in the high temperature/high pressure heater head
  • Blockage of fine-meshed heat matrices used in the regenerator assemblies with particles/fines generated through the rubbing action of piston rings

New materials and technologies may breathe new life into the Sterling engine which has unique advantages for applications in the space, auto and marine industries, as well as in distributed power applications.
