While simulating your model, you must take into account the factors that can alter it, as well as which simulation type would best suit your interests and your system design. You must also take into account the mechanical failures that arise because of various factors and thus can sabotage your simulation results.
As a result, this blog covers simulations and their types, along with some mechanical failures and their reason for their occurrence.
Computer-aided engineering (CAE) is used to simulate performance to improve product designs or help resolve engineering problems for a wide range of industries.
CAE is a way of replicating the deterrents in your system into mathematical models. The simulations can be 1D, 2D, or even 3D.
CAE includes simulation, validation and optimization of products, processes, manufacturing tools and other factors that include -
Here are some pivotal elements of simulation that you need to take into account -
These are the top three factors that influence the results of simulation-driven product development if you are not careful enough -
Here are a few simulations and the way they appear to the users -
GT Power is a 1D simulation tool; however, it has features to incorporate 3D simulation as well.
For instance, when we apply some force on a spring which displaces it, we do not care about the material distribution throughout the cross-section of the spring.
Thus, we model the spring as a rigid bar such that it deflects after the application of force without considering redundant parameters about its cross-section.
1D simulation has certain benefits such as -
Simulink is a MATLAB-based graphical programming environment designed for modelling, simulating and interpreting multi-domain dynamical systems. MATLAB Simulink also has features for 1D simulation.
Some 3D and 2D simulations include -
This simulation is a single stage of the turbine blade system where we simulate centrifugal load.
In this simulation, we have a core and a coil, that when excited, leads to the variation of electric flux and electric flux density.
This simulation contains a PCB that houses some mounted ICs such as IGBT that dissipate high power to observe temperature variations.
Flow simulation is a form of computational fluid dynamics that digitally replicates flows in surface water or collection systems.
Flow simulation facilitates the prediction and analysis of how a flow might get impacted by complex geometry in an operational setup.
In this section, we discuss the typical mechanical failures that occur in systems and their reasons.
The two primary factors that affect fatigue life include -
We observe fatigue failure when the loads are pulsating, be it temperature load, pressure load, or any other category. With repeated loading, your system gets more prone to failure.
Even an automobile at rest on the road experiences vibrations from the engine in its different components. The displacement because of vibration can range from +10mm or -10mm.
Displacement implies a change in load, which varies from -x to +x. When the automobile moves, more vibration flows in via the road.
Mechanical failures arising during simulation-driven product development can affect the integrity and structure of your design. Thus, one needs to keep a sharp eye out for any malfunction in the system.
