Development of Wheel/Rail Contact Procedure in Multibody Railroad Vehicle Dynamics(Mechanical Systems)

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Modeling 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...

development of feminist poetics in adrienne rich

اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...

A Contribution to Computational Contact Procedures in Flexible Multibody Systems

Extension of the Polygonal Contact Model for Flexible Multibody Systems

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 nec...
