- Advances in Structural Dynamic Simulation
Online Seminar
29 - 30 March 2022
NAFEMS, the International Association for the Engineering Modelling, Analysis and Simulation Community is hosting an international seminar designed to showcase Structural Dynamic Simulation.
Structural dynamic simulations at all stages of product development and research are part of the standard procedures in almost all areas of industry. The numerical methods that are used to simulation dynamic events are relatively mature but new capabilities are constantly appearing that allows more complex behaviour to be represented. Higher operating loads, rotational speeds, speeds, lightweight structures, extreme application requirements (natural disasters, accidents, and terrorist attacks), comfort properties (acoustics and vibrations), etc. require a safe and economical design of machines, transport systems, components, plants and buildings with the help of structural dynamic simulations. In addition to the functional, comfort and safety aspects, there are also stricter occupational safety and health regulations that give rise to structural dynamic analyses of constructions.
The use of model reduction techniques allows larger models to be analysed in a time efficient manner, helping dynamic analysis to be more easily integrated into the design process. Model updating technologies and validation with measurements allows high qualified modelling for the simulation methods. Theory, software, and hardware (e.g., HPC and measurement systems) developments have opened up many possibilities for realistic modelling and simulations in structural dynamics. In particular, the combination of FEM, MBD, DEM and acoustic programs, that could incorporate a wide variety of physical and nonphysical inputs, has considerably expanded the possibilities of mapping real relationships of entire systems and complex structures. The boundaries between the different dynamic simulation toolkits have become blurred and the engineer now has a range of options to choose from when tackling a problem. As the range of applications that can be tackled by the different toolkits increased, it provides the opportunity to chain different methods together, to go beyond component and part simulation and start to analyse the whole dynamic system.
The online seminar will be of interest to all engineers using software codes to solve structural dynamic problems. Presenters will be demonstrating how their organisation uses Dynamic Simulation.
Dynamic Simulation comes with unique challenges and the event will:
This online seminar provides an opportunity to gain an appreciation for the wide range of methods that organisations are leveraging it design better products that operate in dynamic environments.
The seminar will include a keynote presentation, several technical presentations, sponsor presentations, round table discussions and exhibits.
We look forward to meeting you virtually at the online seminar.
