Understanding the dynamic behavior of engineering systems is crucial to predicting how they behave when they are subjected to real-world excitations. Linear dynamics using finite element analysis is the most popular way of studying how structures behave when they are subjected to different dynamic environments, such as vibrations and inertial forces. In this learning track, the simulation experts at Ansys have gathered the engineering fundamentals needed for learning how to perform, understand, and interpret results from linear dynamics analyses. Ansys Mechanical will be utilized to give you a strong head start. This learning track is ideal for those who seek to learn fundamentals that can be applied to any commercial finite element tool.
The dynamic behavior of structures is an important concern across many disciplines of engineering. By understanding structural dynamics, civil engineers can design buildings that can withstand severe dynamic loading from earthquakes and hurricanes, aerospace engineers can cont...Read more
Modal analysis is the fundamental dynamic analysis type, providing the natural frequencies at which a structure will resonate. These natural frequencies are of paramount importance in various engineering fields. Suspensions are usually tuned to have different natural frequencies fo...Read more
Do you want to capture the frequency response of a system in a limited loading range of frequency but do not want to solve a large, time-consuming dynamic analysis? Mode superposition (MSUP) is computationally less time consuming and finds the response for a given loadin...Read more
Have you noticed that the sound intensity of a church bell ring decreases with time or that ripples generated in water by throwing a stone vanishes after some time? Why does that happen? Whenever we talk about oscillatory behavior, we hear the term damping. What is damping and wha...Read more
In most engineering problems, we want to predict the response of structures to an external loading/excitation, which is the real-life case. There are many examples where we may see resonance or even failure due to external loading acting at a certain frequency. We...Read more
Every structure undergoes changes over a period; some occur over short time periods while others take a long time. While time is always an independent variable in play, it is not necessary to consider it in analyzing all systems. But how do we identify when time may b...Read more
Time is continuous. Seconds, milliseconds or even microseconds are not the smallest unit of time, because it can be divided into infinite time points. Therefore, in simulation, it’s impossible for us to find a structure’s behavior at every single time point.What we can do is to ...Read more
