Over the last 100 years, the automobile has become integrated in a fundamental way into the broader economy. A broad and deep ecosystem has emerged, and critical components of this ecosystem include insurance, after-market services, automobile retail sales, automobile lending, energy suppliers (e.g., gas stations), medical services, advertising, lawyers, banking, public planners, and law enforcement. These components – which together represent almost $2 trillion of the United State economy – are in equilibrium based on the current capabilities of automotive technology. However, the advent of autonomous vehicles (AVs) and technologies like electrification have the potential to significantly disrupt the automotive ecosystem. The critical cog governing the rate and pace of this shift is the management of the test and verification of AVs.

Carbon Composites (CFRP) have been touted to be an essential component of future automobiles due to their mechanical properties and lightweight. CFRP has been adopted successfully for secondary and primary structures in Aerospace industry. In Automobiles, they are incorporated in models like the BMW i-series. CFRP suffers from 2 major problems. Delamination of Composites leads to catastrophic and rapid failure which could be dangerous in passenger vehicles. Delamination occurs whenever there is a shock on the composite. Secondly, Composites need regular expensive maintenance to ensure that the material is intact and will not compromise passenger safety. Carbon Nanotubes in composites have shown a substantial increase in delamination resistance. A 0.1wt% addition of HiPCO® Single-walled Carbon Nanotube provides both self-sensing and improved fracture resistance. Here we report results of our work with NoPo HiPCO® Nanotubes with small amounts of Iron. 6K Carbon fiber was used as the fiber reinforcement. NoPo HiPCO® Nanotubes were reinforced in the Epoxy system by sonication. HiPCO® Nanotubes were produced using standard parameters. The coupons of CENCE composite were made using VARTM…

The mounting of an engine plays important role in controlling the vibration transmissibility, alignment of transmission unit within specific limit. Design of any mounting system mainly depends on stiffness, allowed deformation and transmissibility of force, natural frequency and size w.r.t space constraints etc. This paper helps to study the behavior of engine mount with different layer of rubber with defer stiffness. Firstly the design of front engine mount with single rubber layer according to space constraint in vehicle and then analysis is done to determine the deformation and various results using CAE technique. As per the results, design is modified with varying layer of rubber pad and again analysis is done with same boundary condition followed by improved results.

Rocker arm in internal combustion engine is very important part which transfer the cam motion and force to the valve. In heavy commercial vehicles, the engine components are design for an infinite life (considerable higher than other components). Recently industries are working for light weight and optimized cost material. Hence it is required to have an optimized cost effective design of rocker arm without affecting its performance. A rocker arm should meet the stiffness and strength requirement. The objective of this study is to find out the alternate material for rocker arm which can provide the similar strength & stiffness as conventional rocker arm material. To achieve the performance and cost target, alternate material cast iron has been evaluated for rocker arm. Cast iron is lighter than the forged steel rocker arm, also it has a good frictional characteristic. Further bush is eliminated from the rocker arm assembly due to self-lubricant property of the cast iron rocker arm. This is significant reduce in cost of material and assembly procedure. A 2-d simulation and finite element…

To be published on 2019-11-21 by SAE International in United States
Fuel lid is one of the parts which are mostly operated mechanically by the end user while filling the fuel. Therefore part design should be done in such a manner that it can be operated smoothly without any hassles. The conventional steel fuel filler doors are of two types: Three-piece type fuel filler doors also known as the dog-leg type and two-piece type fuel filler doors also known as the butterfly type. Both types of fuel filler doors have a pin that acts as a rotational hinge axis about which the fuel filler door opens and closes. Depending on the styling and shape of the side body outer, fuel lid type is decided. In the current study, dog-leg type fuel lid is considered. The factors that primarily affect the opening-closing performance are the weight of fuel lid, hinge axis, and the friction at the hinge area. The orientation of the hinge axis is derived from the profile of the side body outer panel. The fuel lid weight and hinge axis are decided in the initial…
