We analyzed the motion of a 1-meter aluminum rod used as an inverted pendulum after applying an impact to its tip.
We will introduce a case study of control system analysis using nonlinear transient analysis with NX Nastran.
![[Example] Rotating Dynamics Transient Response Analysis](https://image.www.ipros.com/public/product/image/feb/2000006053/IPROS3151219894093263634.jpg?w=280&h=280)
In transient response analysis, in addition to synchronous and asynchronous analyses like frequency analysis, it is also possible to perform analyses where the rotation speed is constant or the excitation frequency is constant while increasing the rotation speed.
【Case Overview】 ■Product Name: NX Nastran ■Analysis: Linear Transient Analysis ■Industry: Other Transient response analysis that calculates the vibration characteristics of the rotor when increasing the rotational speed and the behavior during passing through the critical speed can be performed in addition to synchronous and asynchronous analyses like frequency analysis. It is also possible to conduct analyses where the rotational speed is increased while keeping the rotational speed constant or the excitation frequency constant. This is an analysis along a point or a horizontal line in the Campbell diagram. □For other functions and details, please refer to the catalog.
For evaluating product performance and examining manufacturing processes! We will introduce solutions related to manufacturing and performance analysis.
In recent years, due to the influence of weight reduction and efficiency improvement, the design and material technologies of automotive components have become increasingly advanced, making considerations such as "how to enhance product performance during the manufacturing process" increasingly important. However, in actual manufacturing processes, products are produced through multiple processes, yet many CAE analyses focus solely on one process or physical phenomenon. ESI Group proposes the challenge of reproducing and predicting design and manufacturing processes that include multiple processes, aiming to reduce lead times and costs through virtual prototyping. 【Case Studies】 ■ Fatigue durability analysis considering the casting process By faithfully modeling the pressing, welding, and press-fitting processes and transferring the residual stress and strain from each process, we evaluate the impact on the final fatigue strength performance. ■ Impact analysis considering the die-casting process The strength of die-cast products decreases in proportion to the amount of surface oxides entrained during filling. By providing material strength based on the amount of entrainment calculated through die-casting simulation and conducting impact simulations, we achieved a good correlation with actual machine tests. *For more details, please refer to the PDF document or feel free to contact us.
