Design, Synthesis and Analysis of Loader Bucket, Boom and Linkages for Amphibious Infantry Combat Vehicle

Independent Researcher-Abhijit Kulkarni
Konecranes-Akhilesh Kulkarni
Published 2019-10-11 by SAE International in United States
Currently, for various military activities such as construction of bridges, digging trenches, construction of roads and clearing the area during landslides, separate unit of bulldozer for dozing operation and loader for loading operation is required. But the need is to develop a single unit which could perform both of these operations efficiently and simultaneously. The paper discusses about the development of dozer bucket mechanism as a single unit to perform dozing and loading operation and connected to the amphibious infantry combat vehicle. To develop the dozer bucket mechanism synthesis of mechanism (Linkages and Boom) has carried out and care has taken to fulfill the above stated functional requirement and satisfy the geometrical constraints. The synthesis of mechanism is done with the help of ‘CATIA’ software packages. The force calculation on various joints at the different position of mechanism has evaluated with the help of ’ADAMS’ software. The finite element analysis has done using software ’ANSYS’. The developed mechanism combines the dozing and loading operation and connected to the tracked vehicle.

Sustainability and Production Economics of Titanium for Engine Valve: India Perspective

ARAI Academy Pune-Sagar Patil
Arvind Gavali College of Engineering-Suraj Ghadage
Published 2018-07-09 by SAE International in United States
Automotive industry is looking to have breakthrough for utilization of titanium in vehicles with cost effective solution. This is due to the relative cost factor and for titanium it is 20 and 2.9 times greater than steel and aluminium respectively. Looking at Today’s scenario of multi material vehicle, it weighs approximately 221 kg on usage of conventional materials i.e. aluminium 37%, steel 42% and composites 21%. also Indian government has taken bold decision to meet BS VI norms directly by 2020 and to achieve the same it is required to meet NOx level of 0.06 g/km for gasoline vehicles and 0.080 g/km for diesel vehicle along with EGR rates of 35% at full load at which conventional materials like steel, aluminium has to withstand for high temperature cycles and high compressed air pressure at outlet. Hence positive progress of implementation of titanium by proving its production economy and sustainability for leading automotive components like exhaust system, valve train and turbocharger components in vehicles for the mass market is prime important. But focusing on mass market…

Titanium - A Futuristic Material for Vehicle Exhaust System and Powertrain Components

Vel-Tech-Vikrant Garud, Avinash Arankalle
Published 2014-04-28 by The Automotive Research Association of India in India
India is blessed with considerable quantity of titanium based mineral resources accounting to about 20% of the world's availability holding and third largest reserves. The main titanium minerals are ilmenite and rutile available in beach sand deposits in the coastal states like Kerala with production of about 0.6 MT by mining & mineral separation process to provide environmental friendly titanium alloys. Though the major usage of titanium alloys are for aeronautics, defense, space, atomic energy sectors, its usefulness with special properties is yet to be exploited for the Indian automotive sectors. The principle advantages of Titanium alloys for automotive application that can be exploited are - 45% lighter than steel, virtually total resistant to acidic attack, four times more corrosion resistance than stainless steel, high specific strength, good ductility and ease to form by forging and machining operations. However at present, cost of extraction, alloying with other metals, casting and metal forming processes makes it difficult to penetrate in automotive industry. The R & D efforts are essential between academia, research institutes, and industry to…
