National Symposium on Rotor Dynamics - IIT Madras

December 19,20,21

Most machines have one or more rotating parts. Rotating machine elements thus form the backbone of industrial infrastructure and therefore play a pivotal role in the growth and development of the country. Rotor Dynamics is the key in design and maintenance of all such rotating machinery. This area has made tremendous strides in recent years.

ObCom 2011 - VIT

September 9

This International Conference is a major event to be conducted following the grand success of series of ObCom conferences during 2003, 2004 and 2006, which were audited by a good number of participants from Academia and Industry across the World. The past ObCom conferences received good contributions from academia, industry and research organizations. Our sponsors included governmental and non-governmental agencies like DRDO, ISTE, DIT, CSIR etc.

TRIBOLOGY (Coconut oil As an Alternative to Automobile Lubricants)

Posted by tpapers On 2:30 pm

Abstract:

Increased concerns  about  environmental  damage caused by  mineral  oil  based lubricants, has created a   growing  worldwide  trend  of  promoting  vegetable  oil  as  base  oil  for  automobile  lubricants. Coconut oil which is abundantly available in southern states of India is reportedly being widely used as 2 stroke engine lubricant by autorikshaw drivers. A  survey  among the  users  of  coconut  oil  as  2T  oil brought  forth complaints  of  increased engine  wear. This  paper  presents  tribological  properties  of coconut oil analyzed on the basis of its molecular weight, length of carbon chain, polarity and adhesion tendency  on metallic  surfaces  both at  normal  and elevated temperatures  as  usually encountered in internal combustion (I.C) engines. An experimental study to evaluate the performance of coconut oil as 2T oil was undertaken and the results are presented and discussed. The influence of an extreme pressure additive  on the  tribological  performance  coconut  oil  was  also evaluated experimentally  the  results  are presented and discussed. Recently, the ecological lubricants based on vegetable oil and, other tendency is  to use  synthetic  lubricants, both applications  reducing  the  field of mineral  oil. Biodegradable lubricants will be more used in environment with ecological risk, as for instance, equipment functioning in hygroscopic protected medium, in agriculture, food and wood industry as well as for those with lubricant leakage. The success of vegetal oils is related to their biodegradability and reduced toxicity but a wider use is limited by their insufficient stability in time. This paper presents first experimental results on lubricating capacity of rape seed oil compared to that obtained for a usual mineral oil. From these results it seems that rape seed oil has actual capacity for being used in industrial applications.
