Simulations are computer models used to check the performance of a system in defined conditions. It accelerates the product design process. Therefore products comes to market faster at low development cost. In this article we will discuss advantages and disadvantages of simulation studies.
Advantages Of Simulation
Simulation offers various advantages. They have application in every field. But this article covers the advantages of simulation in mechanical design only.
System Behavior Analysis
Simulations is used to analyze the behavior of a system without actually building it. Therefore engineers can work on alternative solutions to achieve required results.
Various design options are simulated and the best solution is selected for prototyping.
Reduces Manufacturing Cost
Using Simulation we can design products first time right. Therefore manufacturing and testing cost reduces significantly.
Faster Products to Market
Using Simulation studies number of design iterations are reduced. Therefore Design cycle time reduces significantly. This gives companies advantage of launching products in the market faster.
Design Analysis : Visual Output
Simulation results can be exported in visual outputs like graphs. That helps in analyzing system and product output performance.
Simulations are used to analyze a problem at various levels. This leads to faster and effective problem solving.
Simulation studies helps in reducing manufacturing cost of existing and new products. For example mold-flow analysis is used to reduce injection molding cycle time.
Disadvantages of Simulation studies
Higher Initial Investment
Simulation software has disadvantage of high initial investment. Therefore small companies can not afford them. These software are very costly and require high computing power. This Leads to higher system and software cost.
Accurate Boundary conditions and input Data
Accuracy of simulation output results depends on input data and boundary conditions. System boundary conditions includes environmental temperature, pressure and material.
These boundary conditions need to be defined accurately to achieve accurate results. But it is very difficult to predict the boundary.
Not 100% Accurate
Simulation software are not 100% accurate. You should expect some discrepancies in simulation results and tested product. With time engineers can refine their simulation results.
To sum up, Simulation helps in reducing and eliminating design and manufacturing risks. It has advantages and disadvantages. But overall it adds value during new product development. Because Grey areas in design are identified with simulation.
