Title: Optimizing the vehicle’s tire material for improving the vehicle handling attributes

Abstract:

The tire characteristics are significantly effective on the vehicle dynamic attributes including ride and handling. The relation between the tire structure and compounds with the vehicle handling and stability is an important relation that can be very effective in the vehicle performance. The purpose of this study is to optimize the vehicle handling considering the tire constitutive material as design variables. The importance of this issue is significant from several perspectives such as reducing environmental pollution caused by tire consumption, increasing economic efficiency in the field of supply of tire raw materials, keeping the occupants safe while driving and some improvement in car fuel consumption. Achieving such important goals requires accurate models to compute forces and torques on the tire, as well as interactions. In this research, first the finite element tire model was created in the commercial software Abaqus. Then, using this finite element model, the coefficients of the Fiala model as a mathematical model of the tire were extracted. Next, the complete model of the car was created in the Adams software and the tire coefficients of the Fiala model obtained in the previous section was used in this complete model. To perform the dynamic test of the vehicle, Step Steer manoeuvre according to ISO 7401 standard was used. Finally, from the combination of Abaqus model and Adams model and using Taguchi optimization method and considering the roll and yaw angle rates, the tire components were optimized. As a result, a tire that structural materials were different from the original model was obtained, which improved the vehicle handling behaviour with this tire.

Title: Analysis and design of fractal antenna for efficient communication network in vehicular model

Abstract:

Vehicular communication plays a dominant role in providing better safety and security with high rate of data communication in next generation networking infrastructure, and one of the prominent areas for research as well. This article reveals a comprehensive review and design of vehicular communication antenna and its impact with the help efficient archives for efficient solutions. Article also provides some of the critical features communication and its impact on vehicular communication for mobile ad-hoc network. As the technology is advancing towards higher frequencies, in-turn demands a better performing antenna which provides more energy-efficient networking for smart vehicular communication environments. We have provided a design of antenna which could be used for frequencies ranging from 10GHz to 15GHz, and the performance of the antenna measured in the form of Return losses, Voltage Standing Wave Ratio, and Gain. Literature also provides the importance of selecting the substrate for designing the antenna for real-time systems. Three different substrate materials are used in the paper, which are FR4_epoxy, Rogers RT/Duroid 5880^tm, and Rogers RO4003. Eventually, the design made ready with altering/recessed ground, and its impact on the performance of the antenna for all the three different substrates is depicted which could be used for vehicle networks. The size of the patch selected as 40mm X 30 mm with an impedance of 50Ω and a lumped port is used to provide the feed.
