Efficient simulation of mechanism kinematics using bond graphs

Efficient simulation of mechanism kinematics using bond graphs

This paper presents a methodology for obtaining the equations corresponding to a mechanism that are necessary for carrying out a kinematic simulation. A simulation of this kind means obtaining the coordinates dependent on the system according to the movements imposed by the degrees of freedom. Unlike a dynamic simulation, where the set of elements moves according to the different external force...

Vehicle dynamics simulation using bond graphs

This work addresses the construction of a fourwheel, nonlinear vehicle dynamic bond graph model and its implementation in the 20sim modeling and simulation environment. Nonlinear effects arising from the coupling of vertical, longitudinal and lateral vehicle dynamics, as well as geometric nonlinearities coming from the suspension system are taken into account. Transmission and (a simplified) en...

A Method for Efficient Simulation of Hybrid Bond Graphs

The hybrid bond graph (HBG) paradigm is a uniform, multi-domain physics-based modeling language. It incorporates controlled and autonomous mode changes as idealized switching functions that enable the reconfiguration of energy flow paths to model hybrid physical systems. Building accurate and computationally efficient simulation mechanisms fromHBGmodels is a challenging task, especially when th...

Modeling and Simulation of Dynamic Systems Using Bond Graphs

Efficient Simulation of Component-Based Hybrid Models Represented as Hybrid Bond Graphs

Modern engineering systems consist of a large number of interacting components with nonlinear, hybrid behaviors. This makes the building of accurate and computationally efficient simulation models very challenging. Recently, researchers have adopted component[1] and actor-oriented [2] frameworks for modeling of large systems. Such frameworks consist of mathematical models for specifying individ...
