Lightweight design is still very important for an all-electric vehicle especially when used in urban areas. A new active chassis suspension designed for such an urban car is in development at the DLR. The first main component is a composite transverse leaf spring, where a new (partly) automated design and dimensioning process is in development. The...

Developing sustainable products using high persistent and durable materials is challenging. Associated processes to mature innovations in industrial development are often inflexible due to safety reasons and economic requirements. A possible approach to solve these challenges can be found in digitalized development processes. By using optimization...

Important for an all-electric vehicle, especially when used in an urban area, is still lightweight design. Simple chassis systems for small urban vehicles covering those weight limitations often lack an acceptable drive comfort and driving stability in extreme situations. A new active chassis suspension designed for such an urban car is in developm...

Composite materials in automotive structures have the potential to reduce CO2 emissions by simultaneously saving weight and improving fatigue performance. Further weight reduction potential can be obtained by integrating additional functions into composite structures. Regarding a suspension system, the control arms and coil springs in a McPherson f...

As the lightest structural metal, magnesium alloys have been attractive to reduce vehicle weight and emissions by lightweight design in the automotive industry. Up to now, Mg structural casting, such as transmission cases, instrument panels and door inners plays an important role in the lightweight process. Now more and more integrated Mg castings...

Im europaweit einmaligen Forschungsprojekt Reallabor Schorndorf entwickelte ein Team von Expertinnen und Experten aus Wissenschaft und Praxis gemeinsam mit der Zivilgesellschaft ein Bedarfsbussystem. Im Testbetrieb von März bis Dezember 2018 ersetzte das flexible System an den Wochenenden zwei bestehende Busrouten in der Stadt Schorndorf. Im Bedarf...

In the Reallabor Schorndorf research project, which is unique in Europe, a team of experts from science and practice developed an on-demand bus system together with civil society. In test operation from March to December 2018, the flexible system replaced two existing bus routes in the city of Schorndorf on weekends. In on-demand bus operation, pas...

Within the scope of the research project “Reallabor Schorndorf”, funded by the state Baden Wuerttemberg (Germany), demand responsive transport and operating systems as well as a virtual vehicle concept for public transport (PT) were designed and tested in a “real-world laboratory”. The aim of the subproject Vehicle Development was to design a vehic...

Das DLR-FK erarbeitet für Straßen- und Schienenfahrzeuge neuartige und anwendungsorientierte Lösungen. Dazu zählen Konzeption, Konstruktion, Berechnung und Simulation bis zur Darstellung von Forschungsdemonstratoren, -komponenten und -fahrzeugen.

Driven by lightweight goals and strict emission regulations, magnesium and its alloys have attracted increasing attention in the transportation industry. Up to now, Mg structural casting, such as transmission cases, instrument panels and door inners plays an important role in the lightweight process. Now more and more integrated Mg castings with la...

This paper presents the partial results of the first phases of the BOOLEAN (Bürgerorientierte Optimierung der Leistungsfähigkeit, Effizienz und Attraktivität im Nahverkehr) research project. The demand-responsive transport and operating systems as well as virtual vehicle concepts are developed in a "real-world laboratory" in Schorndorf. The demand-...

The article gives an answer to the question, how vehicles that are used for demand-oriented public transport, can in particular be adapted to the users anthropometric needs. For this purpose, users are considered and modeled by means of the digital human model RAMSIS® in order to derive the conceptual design of the vehicle systematicely. The classi...

By the electrification of the drive train, new degrees of freedom also result for the design of new suspension concepts. Especially through the combination of mechanical and electrical components, potentials for future mobility can be raised. These new opportunities offer the potential for electric lightweight suspensions, include integrating drive...

Deflection of the crash opponent is a well-known method to improve general crash behavior, as seen with safety fences on motorways. Within the DLR’s Next Generation Car (NGC) project this behavior was applied to the suspension functions of the Urban Modular Vehicle (UMV), a small, fully battery-electric car for four passengers to cover the needs of...

Within the framework of the project Bürgerorientierte Optimierung der Leistungsfähigkeit, Effizienz und Attraktivität im Nahverkehr (BOOLEAN), demand responsive transport and operating systems as well as vehicle concepts are developed and implemented in a real-world laboratory in Schorndorf. An inter- and transdisciplinary approach integrates persp...

Im Forschungsprojekt „Reallabor Schorndorf“ soll bis Anfang 2019 ein bedarfsgerechtes und nutzerorientiertes System für den öffentlichen Personennahverkehr (ÖPNV) entwickelt werden, bei dem vom Nutzer über Smartphone, Internet oder Telefon der Fahrtwunsch mitgeteilt und die Busroute effizient und flexibel nach den Fahrtwünschen der Nutzer durchgefü...

Das Projekt "Reallabor Schorndorf (BOOLEAN)" ist eines von sieben Forschungsprojekten, die gefördert vom baden-württembergischen Ministerium für Wissenschaft, Forschung und Kunst zukunftsfähige Lösungen für Herausforderungen in Ballungsräume erproben. In Reallaboren bearbeiten dabei Wissenschaftler zusammen mit Kommunen, Unternehmen und Bürgern Ver...

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 bi...

Das Großforschungsprojekt Next Generation Car bündelt die Aktivitäten und Infrastruktur des DLR im Bereich der Straßenfahrzeuge. Dabei werden Methoden und Technologien für die ganzheitliche Entwicklung von Straßenfahrzeugen für morgen und übermorgen an unterschiedlichen Innovationsträgern wie dem NGC Urban oder dem NGC Interurban entwickelt und dar...

Fibre reinforced plastics (FRP) have a high potential for reducing masses of automotive parts, but are seldom used for structural parts in the chassis. If the whole chassis concept is adapted to the new material, then a high weight saving potential can be gained and new body concepts can result. DLR Institute of Vehicle Concepts designed and dimens...

Eine wichtige Funktion heutiger Fahrzeugstrukturen liegt in der Gewährleistung des passiven Insassenschutzes im Falle eines Unfalls. Um die Zahl der Todesopfer und Verletzten im Straßenverkehr zu senken, werden Regularien und Verbraucherschutztests regelmäßig erweitert oder angepasst, um die Entwicklung sicherer Fahrzeugstrukturen zu fördern. Gleic...

The history of terrestrial transport systems on the road has always been influenced by material-related developments. These developments gave rise to various construction methods, taking into account the different requirements that transport systems had to fulfil and provides new approaches. A major motivation for the development of new vehicle str...

Because the strength design serves as a basis for making a decision for or against a certain concept, a C carrier (wheel carrier set system) was extracted from the overall chassis concept in order to eliminate wrong decisions. Then, the developed FE design methods were verified on the basis of this test component. The C carrier includes curved comp...

Weil die Festigkeitsauslegung als Entscheidungsgrundlage fur oder gegen ein bestimmtes Konzept dient, wurde aus dem Gesamt-Fahrwerkkonzept ein C-Trager (Radtragerersatzsystem) extrahiert, um Fehlentscheidungen auszuschliesen. Anhand dieses Prufbauteils sollten dann die entwickelten FE-Auslegungsmethoden verifiziert werden. Der C-Trager beinhaltet...
