An introduction to the career of a mechanical engineer

Hi Vish Thanks for the comment Difficult one really. The blog is primarily about working in F1 as an engineer or mechanic but I have had quite a few queries about starting in racing.

An introduction to the career of a mechanical engineer

Model-based systems engineering A graphical representation relates the various subsystems or parts of a system through functions, data, or interfaces.

Any or each of the above methods are used in an industry based on its requirements. - Limitless Career Opportunities

For instance, the N2 chart may be used where interfaces between systems is important. Part of the design phase is to create structural and behavioral models of the system.

Once the requirements are understood, it is now the responsibility of a systems engineer to refine them, and to determine, along with other engineers, the best technology for a job. At this point starting with a trade study, systems engineering encourages the use of weighted choices to determine the best option.

A decision matrixor Pugh method, is one way QFD is another to make this choice while considering all criteria that are important. The trade study in turn informs the design, which again affects graphic representations of the system without changing the requirements.

In an SE process, this stage represents the iterative step that is carried out until a feasible solution is found. A decision matrix is often populated using techniques such as statistical analysis, reliability analysis, system dynamics feedback controland optimization methods. Other tools[ edit ] Systems Modeling Language SysMLa modeling language used for systems engineering applications, supports the specification, analysis, design, verification and validation of a broad range of complex systems.

The following areas have contributed to the development of systems engineering as a distinct entity: Cognitive systems engineering Cognitive systems engineering CSE is a specific approach to the description and analysis of human-machine systems or sociotechnical systems.

CSE has since its beginning become a recognized scientific discipline, sometimes also referred to as cognitive engineering. The concept of a Joint Cognitive System JCS has in particular become widely used as a way of understanding how complex socio-technical systems can be described with varying degrees of resolution.

The more than 20 years of experience with CSE has been described extensively. Control engineering Control engineering and its design and implementation of control systemsused extensively in nearly every industry, is a large sub-field of systems engineering. The cruise control on an automobile and the guidance system for a ballistic missile are two examples.

Control systems theory is an active field of applied mathematics involving the investigation of solution spaces and the development of new methods for the analysis of the control process.

Industrial engineering Industrial engineering is a branch of engineering that concerns the development, improvement, implementation and evaluation of integrated systems of people, money, knowledge, information, equipment, energy, material and process. Industrial engineering draws upon the principles and methods of engineering analysis and synthesis, as well as mathematical, physical and social sciences together with the principles and methods of engineering analysis and design to specify, predict, and evaluate results obtained from such systems.

Interface design Interface design and its specification are concerned with assuring that the pieces of a system connect and inter-operate with other parts of the system and with external systems as necessary.

Interface design also includes assuring that system interfaces be able to accept new features, including mechanical, electrical and logical interfaces, including reserved wires, plug-space, command codes and bits in communication protocols. This is known as extensibility.

Systems engineering principles are applied in the design of network protocols for local-area networks and wide-area networks. Mechatronic engineering Mechatronic engineeringlike systems engineering, is a multidisciplinary field of engineering that uses dynamical systems modeling to express tangible constructs.

In that regard it is almost indistinguishable from Systems Engineering, but what sets it apart is the focus on smaller details rather than larger generalizations and relationships.

As such, both fields are distinguished by the scope of their projects rather than the methodology of their practice. Operations research Operations research supports systems engineering.

The tools of operations research are used in systems analysis, decision making, and trade studies. Several schools teach SE courses within the operations research or industrial engineering department, [25] highlighting the role systems engineering plays in complex projects.

Operations researchbriefly, is concerned with the optimization of a process under multiple constraints. Performance is usually defined as the speed with which a certain operation is executed, or the capability of executing a number of such operations in a unit of time.

Performance may be degraded when operations queued to execute is throttled by limited system capacity. For example, the performance of a packet-switched network is characterized by the end-to-end packet transit delay, or the number of packets switched in an hour.

The design of high-performance systems uses analytical or simulation modeling, whereas the delivery of high-performance implementation involves thorough performance testing.

Performance engineering relies heavily on statisticsqueueing theory and probability theory for its tools and processes. Program management and project management Program management or programme management has many similarities with systems engineering, but has broader-based origins than the engineering ones of systems engineering.

Project management is also closely related to both program management and systems engineering. Proposal engineering Proposal engineering is the application of scientific and mathematical principles to design, construct, and operate a cost-effective proposal development system.

Basically, proposal engineering uses the " systems engineering process " to create a cost effective proposal and increase the odds of a successful proposal.

Reliability engineering Reliability engineering is the discipline of ensuring a system meets customer expectations for reliability throughout its life; i. Next to prediction of failure, it is just as much about prevention of failure.Mechanical engineering deals with any machine that moves, such as robots, motors, pumps, and vehicles.
