Friction in Sheet Metal Forming: Forming Simulations of Dies in Try-Out
The quality of sheet metal formed parts is strongly dependent on the tribology and friction conditions that are acting in the actual forming process. This paper focuses on the tribology conditions during early try-out of dies for new car models. The motivation for the study is that the majority of the forming simulations at Volvo Cars are performed to secure the die try-out, i.e. solve as many problems as possible in forming simulations before the final design of the die and milling of the casting. In the current study, three closure parts for the new Volvo V60 model have been analysed with both Coulomb and TriboForm friction models. The simulation results from the different friction models are compared using thickness measurements of real parts, and 3D geometry scanning data of the parts. Results show the improved prediction capability of forming simulations when using the TriboForm friction model, demonstrating the ability to accurately describe try-out conditions in sheet metal forming simulations.

Friction in Sheet Metal Forming Simulations: Modelling of New Sheet Metal Coatings and Lubricants
The quality of sheet metal formed parts is strongly dependent on the tribology and friction conditions that are acting in the actual forming process. These friction conditions are then dependent on the tribology system, i.e. the applied sheet material, coating and tooling material, the lubrication and process conditions. Although friction is of key importance, it is currently not considered in detail in sheet metal forming simulations. The current industrial standard is to use a constant (Coulomb) coefficient of friction, which limits the overall simulation accuracy. Since a few years back there is an ongoing collaboration on friction modelling between Volvo Cars, Tata Steel, TriboForm Engineering, AutoForm Engineering and the University of Twente. In previous papers by the authors, results from lab scale studies and studies of a door-inner part in Volvo Cars production have been presented. This paper focuses on the tribology conditions during early tryout of dies for new car models with an emphasis on the effect of the usage of new steel material coatings and lubricants on forming results. The motivation for the study is that the majority of the forming simulations at Volvo Cars are performed to secure the die tryout, i.e. solve as many problems as possible in forming simulations before the final design of the die and milling of the casting. In the current study, three closure parts for the new Volvo V60 model have been analysed with both Coulomb and TriboForm friction models. The simulation results from the different friction models are compared using thickness measurements of real parts, and 3D geometry scanning data of the parts. Results show the improved prediction accuracy of forming simulations when using the TriboForm friction model, demonstrating the ability to account for the effect of new sheet metal coatings and lubricants in sheet metal forming simulations.

Kinect Controlled UGV
Extensive research has been done on various techniques for navigation of automobiles and robots using diverse motion sensing input devices. This paper presents a unique approach of using Kinect for navigation with options of controlling manually or autonomously or with combination of both. A rover with the navigation control through human gestures, voice and self (adaptive) is presented. The prime application of this project is in the automotive industries. A prototype is developed and tested. The main objective is to facilitate the users by introducing gesture and voice control automobile model. The Kinect (optical sensor) allows users to experience a human robot interaction. It is able to provide an intuitive, robust and fun form of interaction It can control a wide range of operations such as acceleration, braking, steering, media, volumes etc. just from gesture or voice. This rover can be used in home, industries, hospitals, restaurants etc. The system is intelligent and adaptive to avoid obstacles on its path. Gesture and voice controlling is very helpful for handicapped people to achieve certain tasks, such as driving etc. Rover can also be used in auto mode to follow the points that are given through Google/Bing map. The auto mode converts the rover into a self-driving car.

Optimization of rental systems : queuing loss theory for the optimization of cargo vehicle rental systems
Logistics providers typically own large fleets of transportation vehicles such as rail cars or trucks. These fleets do not only determine to a large extent the service level the company can offer, but also make up a large part of total costs. Proper management of the fleet is therefore a crucial factor for these companies. In this book the author presents planning approaches that address the optimal management of vehicle fleets. Firstly, methods for determining the mixture of vehicle types and the optimal size of a fleet are developed. Secondly, approaches for supporting new service models such as customer segmentation are derived. Potential readership includes scholars and graduate students who are interested in the field of fleet planning and practitioners from logistics companies looking for new planning approaches.
