Analysis of the response of a cracked jeffcott rotor to axial excitation
(2002)The coupling of lateral and longitudinal vibrations due to the presence of transverse surface crack in a rotor is explored. Steady state unbalance response of a Jeffcott rotor with a single centrally situated crack subjected ... -
Ant colony optimization algorithm to the inter-cell layout problem in cellular manufacturing
(2004)The inter-cell layout problem is discussed and a mathematical formulation for material flow between the cells is presented. The problem is modeled as a quadratic assignment problem (QAP). An ant algorithm is developed to ... -
Application of fracture mechanics in the failure analysis of a last stage steam turbine blade
(1998)This paper discribe the application of fracture mechanics principals in the failure investigation of a last stage steam turbine blade of the nuclear power plant at Narora in india.The machine failed in the early morning ... -
An approach towards fatigue wear modelling
(1996)Experiments have been conducted in a disc machine under rolling/sliding contact with EN3I and a mild steel disc pair in boundary lubrication. The wear has been modelled oxa the basis of asperity fatigue due to repetitive ... -
Attribute based specification, comparison and selection of a robot
(2004)The problem of robot selection has been of concern to manufacturers for many years. This problem has become more difficult in recent years due to increasing complexity, available features, and facilities offered by different ... -
Burn properties of fabrics and garments worn in India
(2000)A full-scale human form dummy was designed for studying the burning of common dress assemblies (i.e. combination of garments) worn in India. The dummy was made in eight parts; each made of a steel shell filled with water ... -
Combustion and gasification characteristics of rice husk
(1992)Rice husk when used in gasifiers and boilers yields carbonaceous residue. Combustion and gasification studies of rice husk were carried out to understand the problem of incomplete carbon conversion. Thermogravimetric ... -
Comparative study of model updating methods using simulated experimental data
(2002)The inverse eigensensitivity method and the response function method of analytical model updating have become relatively more popular among other methods and have been successfully applied to the practice of analytical ... -
Composite shaft rotordynamic analysis using a layerwise theory
(1996)Formulations are presented for the rotordynamic analysis of a composite rotor supported on general eight coe.cient bearings obtained by using conventional equivalent modulus beam theory (EMBT) and a layerwise beam theory ... -
Computer aided detection of isomorphism among kinematic chains and mechanisms using the concept of modified distance
(Elsevier Science, 1996)A computer aided method has been proposed for detecting isomorphism among planar kinematic chains with sample joints using a new invariant called the arranged sequence of modified total distance ranks of all the links ... -
Computer simulation of a combined cycle power plant
(1995)This paper presents the simulation procedure developed to predict the performance of a combined cycle power plant from given performance characteristics of its main components. In order that the procedure could be validated, ... -
Computer-aided optimum selection of roller bearings
(1993)The paper presents a methodology for evaluating roller bearings in terms of their suitability for a given application. The method is based on a multiple-attribute decision-making approach called (Technique for Order ... -
Coupled bending, longitudinal and torsional vibrations of a cracked rotor
(2004)The coupling between longitudinal, lateral and torsional vibrations is studied together for a rotating cracked shaft. These coupling mechanisms have been studied here with a response-dependent non-linear breathing crack ... -
Cross-section deformation of tubular composite shafts subjected to static loading conditions
(2002)Theoretical and experimental studies have been carried out on deflection and cross-section deformation of tubular composite shafts subjected to point static loading. Out of plane displacement, which is absent for metallic ... -
Damped free vibrations of layered composite cylindrical shells
(1994)System loss factors corresponding to various shell modes have been evaluated by using a complex modulus approach. The damped free vibrations of composite cylindrical shells have been analyzed by using a first order shear ... -
Damping studies in fiber-reinforced composites -a review
(1999)The status of research on damping in fiber-reinforced composite materials and structures with emphasis on polymer composites has been reviewed in this paper. As a first step, composite damping mechanisms and methodology ... -
A decomposition of the manipulator inertia matrix
(1997)A decomposition of the manipulator inertia matrix is essential, for example, in forward dynamics, where the joint accelerations are solved from the dynamical equations of motion. To do this, unlike a numerical algorithm, ... -
Delamination propagation in rotating carbon-epoxy composite shaft
