Die Bachs sind die größte Musiker-Dynastie aller Zeiten. Die Wurzeln dieser berühmten Familie und ihre musikalischen Anfänge liegen im Gothaer Land. Hier spielte am Anfang des 17. Jahrhunderts der Wechmarer Müller Vitus Bach auf dem Cythringen und wurde zum Stammvater des musikalischen Bachgeschlechts. Seine Söhne und Enkel zogen musizierend durch das Land und machten sich überall in Thüringen einen Namen als begnadete Musiker. Über Generationen hinweg schallte der Ruf der Bachs in die Welt, blieb aber auch weiterhin unmittelbar mit dem Gothaer Land verbunden. Johann Sebastian Bach erlernte in Ohrdruf das Orgelspiel und brachte Ostern 1717 in der Gothaer Schlosskirche seine erste Passion zur Aufführung. Aber auch abseits des wohl weltweit bekanntesten Bachs waren über zwei Jahrhunderte hindurch zahlreiche Mitglieder der Familie in diesem Raum als Kantoren, Organisten, Lehrer und Geistliche tätig. Der Band widmet sich in 22 Beiträgen dem Leben und Wirken dieser musikalischen Großfamilie und gibt zugleich Einblicke in das Bach-Erbe und die Bach-Traditionen des Gothaer Landes.

Experimental tests on the type-approval of motor vehicles with regard to safety belt anchorages, ISOFIX anchorages and ISOFIX top anchorages have been carried out in accordance with Regulation No. 14 UNECE. From the design stage, the safety belt anchorages must comply with the requirements for the installation of a safety belt and reduce slipping and damage to the belt while wearing it. These can be components of the seat structure or of the body's resistance structure, which have the role of fastening the seat belts. The position of the anchor points is determined by the R point. The R point is defined as the seat reference point on the seat. This point is set by the vehicle manufacturer for each seat in the vehicle. In this paper, two models of chairs were tested. Both seat models are equipped with seat belts anchored at three anchor points. Seat belt anchorages were tested simultaneously using parallel force devices. These traction devices are placed on the seat cushion and are pressed into the seat back. The pulling device has a vertical pulling arm, which has the role of anchoring the steel wire cables. Two test forces are applied simultaneously to the anchor points during the test.
This study aimed to investigate the component structural behaviour and response under overturned truck crash that subsequently collides with road-side pole or tree. The safety of the truck occupants in an accident is very important and should be considered in the process of cabin design. Specific focus will be on the structural integrity of the truck cabin in response to a collision with a cylindrical pendulum. In the past, dynamic analysis was done by real world testing. Nowadays crash simulation is proven to be much more efficient by being a virtual representation of destructive crash impact and providing opportunities to reduce the number of physical prototypes consumed for design verification, thus reducing development time. According to cab strength tests (ECE R29), the cabin body of the truck shall be attached to the chassis in such a way that in the event of impact it ensures a sufficient survival space and eliminates the risk of injury. This paper investigates the FE (finite element) simulation of a frontal impact on the cabin structure to validate the cabin according to the ECE regulation 29 tests. The study also includes the assessment of the energy absorption capabilities of the cabin during the pendulum impact. The pendulum impact was carried out using Ansys LS-Dyna explicit solver to evaluate the cabin strength under the loads.
