Boundary conditions inaddition to the specimen size in case of nonlinear materials could be evenmore effective. Hence, a full analysis of these parameters before doing anytest on the real material seems necessary. In this paper, these effects arenumerically analyzed, using ANSYS APDL coding. Samples are cylindricalelastomers becoming ready for a relaxation test in order to get Prony seriesof the material. The influences of friction and applied displacement inaddition to the area-length ratio have been investigated and the optimalvalues in order to do an appropriate relaxation test are proposed.Modelling of Kinematics and Dynamics of the IPAnema 3 Cable Robot for Simulative Analysishttps://puma.ub.uni-stuttgart.de/bibtex/26dfb1c595dcdf07dd90a840143f650ce/isw-bibliothekisw-bibliothek2016-03-09T11:44:11+01:00cable-driven modeling pn3-7 parallel dynamics cable-robot kinematics robots isw-2015 cdpr isw <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Philipp Tempel" itemprop="url" href="/person/1890242751b3b4f431fbeb708e4d61efc/author/0"><span itemprop="name">P.

The plant behavior may change over the entire life cycle due to component-specific time-variable factors. Control valves applied in compressor plants are affected by time-variable factors. Their modeling with consideration of specific time-variable factors is described in this paper. Control valves ensure functional reliability of the plant, as they are opened to blow off excessive compressed process fluid in order to prevent surging and thus to protect the compressor from dam-age. The influences of the time-variable factors fouling, leakage, changing friction force and loss of supply energy are investigated and integrated into the valve model. Fouling of the valve affects the overall flow and control behavior. Further on, leakage can occur in all flooded components and may jeopardize the func-tional capability, as required pressure values cannot be reached. In order to avoid leakage at the actuator, stuffing boxes are used for sealing the piston rod. These boxes cause friction forces, which depend on tightening force, temperature and wear of the box. Changing of friction force leads to deviating travel paths or even stick-slip effects. Furthermore, the provided pneumatic energy to run the control valve might be variable. Energy sources with insufficient performance lead to significant changes in movement time, because the provided pressure collapses once the control valve is opened. It can be stated that all investigated fac-tors affect the positioning behavior and lead to deviating move-ment times, travel paths or end positions. The developed model-ing approach depicts all of these changes and the gained knowledge can be used for developing diagnosis methods. Several model parts, especially the modeled variable factors, are reusable for other components, like non-return and throttle valves or even the compressor itself. Hence, a diagnosis system for the whole compressor plant, based on the modeled influences, can be devel-oped.Kinematics and Dynamics Modeling for Real-Time Simulation of the Cable-Driven Parallel Robot IPAnema 3https://puma.ub.uni-stuttgart.de/bibtex/2a548f40a68a487e59ca8a2324a074462/isw-bibliothekisw-bibliothek2016-03-09T11:44:36+01:00cable-driven modeling pn3-7 dynamics cable-robot kinematics isw-2015 cdpr isw <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Philipp Tempel" itemprop="url" href="/person/141c9eb2026b6b2316d264b040956d509/author/0"><span itemprop="name">P.

The governing equations of motion of the mobile platform are acquired using Newton-Euler formalism, furthermore, the pulley kinematics of the winches and a spring-damper based cable model are introduced. Once the equations of motion are derived, closed-form force distribution is implemented and simulation results of the real-time capable model for the cable-driven parallel robot IPAnema 3 is presented. Given the real-time capability, the established model can be used for hardware-in-the-loop simulation or controller design, but also for case studies of highly dynamic or large-scale robots.A Model- and Signal-based Power Consumption Monitoring Concept for Energetic Optimization of Machine Tools: A Model- and Signal-based Power Consumption Monitoring Concept for Energetic Optimization of Machine Toolshttps://puma.ub.uni-stuttgart.de/bibtex/22235e99e05cfd03e6816b2176708e811/isw-bibliothekisw-bibliothek2016-03-03T09:53:12+01:00energy xsl modeling efficiency optimization ECOMATION machine monitor consumption tools ISW <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Jan Schlechtendahl Alexander Verl Eberhard Abele Philipp Eberspächer, Philipp Schraml" itemprop="url" href="/person/1fb4aec8f71943a87fa06adcb90b36ab5/author/0"><span itemprop="name">J.

However, it is not sufficient to provide the current overall power consumption but to give different levels of detail. This paper presents an approach to combine power measurements, control signals and information with consumption simulation models to provide the operators with highly detailed power consumption data and how it is distributed over the components of their machine tools. An implementation of the monitoring approach on a HSC milling machine is presented in detail, followed by an overview of its use for energetic optimization.
