Suspension and address prototype modeling in computer. Due to the increasing complexity of the analysis carried out in all branches of mechanical engineering, computer-aidedcalculation has always acquired greater prominence. There has been an evolution in the representation of physical systems from outlined parts of the system as a way to reproduce the whole in verbosemode. This process has been possible largely due to the constant improvement of benefits of computer equipment, and the improvement of calculation programs.
In the design of new components, the use ofthese tools allow in most cases get more accurate results and especially a reduction in costs by allowing virtually analyze the behavior of new solutions.
Calculation as the finite element analysistools are used in the process of analysis and design (FEA for its acronym in English) or finite volumes as well as computational fluid dynamics (CFD). The design of manufacturing processes with thehelp of computers (CAM), allows the generated models can be directly used to create "instructions" for the manufacture of objects represented by the models, by means of numerical control (CNC)machines or other automated processes, without the need for intermediate drawings.
There are independent associations that provide information and develop norms of calculation in the field of analysis andsimulation. One of the most important is the National Agency for Finite Element Methods and Standards (NAFEMS), organization non-profit made up of more than 700 companies from around the world.Mechanical engineering helps in a better comfort of taxpayers. The following are the most widespread analysis and design software packages:
