Extension of the Polygonal Contact Model for Flexible Multibody Systems
نویسندگان
چکیده
The Polygonal Contact Model or PCM is originally an algorithm for contact analysis between rigid bodies with complicated geometries in multibody dynamics. In applications where the flexibility of contacting bodies is not negligible, rigid body contact modeling can not achieve realistic results and elastic body contact modeling should be utilized instead. Therefore, due to the importance and necessity of considering elastic deformations, the extension of PCM for elastic bodies was required and is described in this paper. With the described modifications and extensions PCM is also applicable for contact modeling between flexible bodies with reasonable efficiency. For this purpose, geometric and kinematic information is updated repeatedly during the simulation and different options are implemented and compared.

Development of a Finite Element Methodology for Flexible Track Models in Railway Dynamics Applications
The dynamic analysis of railway vehicles involves the construction of three independent models: the vehicle model; the track model; and the wheel-rail contact model. In this work, a multibody formulation with Cartesian coordinates is used to describe the kinematic structure of the rigid bodies and joints that constitute the vehicle model. A methodology is also proposed in order to create detail...
متن کاملModeling Intermittent Contact for Flexible Multibody Systems
This paper consists of two parts. The first part presents a complementarity based recursive scheme to model intermittent contact for flexible multibody systems. A recursive divide and conquer framework is used to explicitly impose the bilateral constraints in the entire system. The presented approach is an extension of the hybrid scheme for rigid multibody systems to allow for small deformation...

متن کاملEnd-Effector Trajectory Tracking Control of a Parallel Flexible Manipulator
End-effector trajectory tracking of flexible multibody systems is often a challenging task. This is due to the fact that flexible multibody systems possess less control inputs than degrees of freedom, i.e. they are underactuated. Thus, classical approaches known from fully actuated systems cannot be applied. The complexity might be further increased, if the multibody system includes additional ...
