Simulation-Based Design of Dynamic Systems
Determination of Operating Loads
The determination of design loads is aimed at the design of components. These components are subject to various requirements. Some of them are contradictory.
Motivation
Precise knowledge of the design loads enables components to be designed safely and tailored to requirements. This makes it possible to avoid oversizing. The positive result is saving material, energy and costs.
Goal
Our goal is to develop methods that simplify the process of determining operating loads and make it more resilient. This should enable applicants to design operating loads as efficiently and safely as possible.
Approach
In addition to the necessary modeling of multi-body models, the operating scenarios play a very important role. Information about velocities, excitations or motion requirements, for example, are collected in operational scenarios. The data content of these scenarios is decisive for the quality of the design loads. Influence analyses and other suitable statistical methods are used to identify relevant parameters and integrate them into the scenarios. Thereby, a reduction of the simulation effort should be achieved.
Multibody Simulation
Simulation-Based Design of Dynamic Systems
At IGMR, methods of multibody simulation are researched to improve the applicability and validity of multibody simulation for the simulation-based design of dynamic systems.
With multibody simulation, the dynamic behavior of mechanical and mechatronic systems can be analyzed. It is therefore an important tool for the simulation-based design of such systems. At IGMR, we work on methods to improve the applicability and validity of multibody simulation for the simulation-based design process.
Motivation
Multibody simulation is a method for the simulation of mechanical and mechatronic systems. A multibody system consists of several rigid or flexible bodies, which are connected through joints, springs, dampers and positioning elements and usually perform large nonlinear motions. With multibody simulation, the dynamic behavior of such systems, for example the interaction between forces and motions, can be analyzed. Fields of application are, among others, robotic systems, production and packaging machines, automotive engineering, and machine dynamics. Therefore, multibody simulation is an important tool for the simulation-based design of dynamic systems.
Goals
Multibody simulation is an important tool at the institute and is used in many research and industry-related projects for analysis and design. In addition to its application, IGMR also researches on different methods in the field of multibody simulation. The goal is to improve the applicability and validity of multibody simulation for the simulation-based design of dynamic systems.
Approach
Based on different applications in the fields of robotics and vehicles, IGMR works on different methods for the simulation and design of multibody systems. This includes multi-objective optimization methods, modeling methods for multibody systems with flexible bodies, numerical methods for real-time simulation and semi-analytical approaches for multibody simulation based on sensor data.
