Light Electric Vehicles for Muscle–Battery Electric Mobility in Circular Economy: A Comprehensive Study

Light electric vehicles (LEVs) facilitate a significant reduction in global warming potential (GWP) and other environmental impacts related to specific transport performance due to their lightweight construction. Low-voltage systems in the drive engine, an open vehicle design and online vehicle data processing allow LEVs to be repaired by independent workshops, thus enabling long vehicle use as well as conversion or retrofitting for periods of use beyond 20 years. LEVs are not yet very common in everyday life in Western Europe. In order to support the acceptance of muscle power-supported LEVs in the EU L7e registration class by users, the vehicle design and construction specifically address requirements in the areas of last-mile parcel delivery and other transport services, including passenger transport. Life cycle assessment was used to investigate two construction methods for LEVs, mixed construction and fibre composite construction, in terms of the production, service life phase and end of life. A vehicle configuration was developed which, in addition to resource-saving production and long-life operation, enables easy access for users and maintenance of the LEV for various purposes. The resource efficiency of light electric vehicles was proven with regard to the ecological aspects. The vehicle design shown here shows high potential for LEVs in the circular economy.

Unmanned Aerial Vehicle Design for Application in Cyber Security

In this paper a small copter size unmanned aerial Vehicle (UAV) has been designed as a platform for a flying computer station to carry out cyber-attacks (Jamming, Spoofing, Man in the Middle, etc.) on devices that utilize wireless technologies, WiFi in particular. A yagi-patch hybrid antenna designed for 2.4 GHz freely rotates on two axes, thus allowing the drone to perform attacks on low power devices up to ranges of 300 meters. The modular design of the UAV allows for quick swapping of modules depending on the specific wireless technology used by the target device.

NVH Analysis of Acoustic Materials by Using Aluminum, Steel and Carbon Fiber for Vehicle Design

The vehicle acoustic overall performance optimization in an undertaking to determine the difficulty of sound techniques turned into created the noise within the cabin. In this paper to audit the advancements so far did in the discipline of optimization thinks approximately on lower of noise within the truck cabins with the aid of the use of acoustic materials. In mild of this, it’s miles to analyze the opportunity of acoustic substances as aluminum, steel metallic and carbon fiber with plan to improve the cabin noise by NVH evaluation may be finished via using ansys and hypermesh software program’s. By locating the analysis values of frequency, sound and weighted sound can be concluded the acoustic materials are excellent for quieter programs.

Cost-Effective Remote Operated Vehicle

Remote operated vehicles (ROVs) are robotic submersibles controlled typically by a person at the surface of a water body. ROVs can be applied to surveillance, environmental, and data recording jobs or tasks. The vehicle design may be modified to remove or add additional capabilities depending upon the specific purpose of the ROV. In this paper, we explore using remote operated vehicles as a cheap and affordable water exploration platform. ROV’s high cost is a prohibitive barrier to entry, preventing widespread adoption of ROV for personal, research, and conservation uses. To address this problem, our paper explores a cost effective ROV with video capturing and directional control capabilities. Using state-of-the-art robotic technologies, a cost-effective competitive ROV is designed and constructed. This ROV was tested to a depth of 7 meters and has the potential to reach depths of up to 30 meters per its design.
