New approach for a comprehensive method for urban vehicle concepts with electric powertrain and their necessary vehicle structures
By the strict discussions regarding energy saving and the goal to reduce CO2 emissions to 95g CO2/km, which is specified for the year 2020, [1] there is a keen demand for lighter and lightweight designed automotive structures to support the energy saving targets. In view of a holistic approach and also to prospectively meet the requirements of the automotive sector, beside the previously mentioned challenges, economic and production-orientated aspects, as well as joining technologies, within the scope of multi-material design, have to be considered to realize a great leap forward medium to large-scale productions.
To achieve these goals, a comprehensive method for urban vehicle concepts with electric powertrain and their necessary vehicle structures is presented. The dimensions and packaging of the presented vehicle is based on demands of a future urban vehicle with space for four occupants including baggage, steerable front system wheels and a rear axle including an electric powertrain.
At the beginning of the method the relevant user requirements, e.g. space for persons and baggage, range for the urban vehicle are defined. In addition, input variables are discharged through the state of the art of electric vehicles. It is also an important point in this step to look on further requirements such as crash requirements or requirements for electrical components in the vehicle design.
With the defined requirements the package of the urban car has to be defined. Two paths are determined to a geometrically and a simulative way. The simulative consideration is limited to the vehicle longitudinal dynamics, thus a rough dimensioning of the drive components is derived. The outputs of the simulation are the performance measures which are then converted into components for the overall model for dimensioning for example electric motor or battery.
The geometric design phase begins with the positioning of the occupants in the passenger compartment and ergonomic layout. Based on this conception of the complete vehicle, various FEM optimizations (topology, topography, size) are carried out for the body in white in order to construct structures towards individual (functional) components/modules. This top-down approach raises the opportunity to extract constructive innovations, which must be integrated within this early concept phase, also to reduce costs when aiming to development of a series product.
With this holistic approach a load-specific optimized structural design is virtually generated and evaluated, and also an outlook on dynamic loads (crash behavior) is given. The focus here is on the potential in innovations by the definition of novel package alignments in combination with the useful application of multi-material-design method, resulting in a light modular vehicle structure

An Emission-free Modular Vehicle Concept for Inner Urban Transportation in Near Future Megacities (Urban MoVe-T)
As the demands for fast and sustainable transportation in megacities are growing, new transportation concepts with full electric vehicles for the distribution of goods are needed. Not only the “last mile” is important for the delivery of small goods, but also the distribution from the big logistic centres in the outskirts to the inner city has a big influence on the volume of traffic. A new concept for a zero emission vehicle, the “Urban MoVe-T” (Urban Modular Vehicle for Transportation) has been developed within the Institute of Vehicle Concepts to meet these new requirements It consists of two parts, the “Ultra Mobility Tractor” (UMT) and secondly different “Intelligent Versatile Modules” (IVM). The concept of the one-axle-two-wheeled UMT is comparable to the well-known Segway© technology, but includes an additional driver cabin and an integrated safety cell for the driver. Moreover the UMT has an innovative wheel integrated bearing and chassis suspension system. This suspension system includes an innovative electric motor coupling, which enables to keep the unsprung masses low, while providing the unit compact. With the vehicle`s tractor module the driver has a high manoeuvrability, which is important, when used for delivery in historic city centres like Vienna. Coupled with the smallest Intelligent Versatile Module, the whole transportation vehicle has a total length of 2.5m and width of 1.7m, but is capable to carry two euro-pallets with a payload of 1t each. The vehicle has the highest payload per vehicle volume rate up to date. Due to its compact dimensions it enables the new concept to be integrated in existing infrastructures like into the commuter railway system. It can be parked transverse to the direction of travel of the train and can later on leave the train without changing the direction itself. The IVMs used for carrying the load all have 360° turn able wheels for manoeuvring on the spot to meet the requirements for the usage with the UMT. As all the IVMs have their own electric drive system, the load modules are able to drive independently when used on restricted sites like in distribution centres in the outskirts of the megacities. A bigger version of the IVM is able to carry six euro-pallets and has the dimensions of 3.5m length and 2.5m width; in total the tractor/load module combination has a total length as well as a turning radius of less than 5m, which is an unchallenged value for a vehicle in the sector of transportation. The big IVMs are also capable to be put autonomous onto the train for a fast and effective transportation from the distribution centre into the city centre. There the UMTs could fetch the IVMs and bring them to their destination. So a whole new effective distribution can be achieved with a significant reduction of the overall traffic on the streets of the big cities

Особенности строения и геофизическая характеристика юрских конгломератов восточной части Нюрольской впадины (Томская область)
Изучено положение в разрезах, особенности строения, условия накопления и разнообразие постседиментационных преобразований конгломератов из юрской продуктивной толщи восточного склона Нюрольской впадины (Томская область). Установлено, что базальные и внутриформационные конгломераты с содержанием обломков свыше 50 %, залегающие в подошвах циклитов, указывают на начало новых седиментационных циклов при усилении тектонической активности в областях сноса. Геофизические характеристики конгломератов не позволяют однозначно выделить их на каротажных диаграммах
Schnelle Schwerlast-FTS im Werksgelände : Automatisierungslücke im Materialfluß von Werksarealen schließen
Aus verschiedenen Gründen war es bisher nicht möglich, fahrerlose Transportsysteme außerhalb von Hallen, also im Werksareal einzusetzen. Allerdings begann 1985 ein vielversprechender Pilotversuch mit einem "Outdoor-FTS" mit einem Schweizer Chemiewerk. Im folgenden Beitrag wird zunächst über die dort gesammelten Erfahrungen berichtet. Darauf aufbauend werden z. Z. die Komponenten des Systems weiterentwickelt, um in den nächsten drei Jahren eine serienreife Produktfamilie von schnellfahrenden Schwerlast-FTS zu schaffen
