Crankshaft is a very crucial part in internal combustion engine. This paper presents the finding of mode shape and natural frequency of a 3 cylinder 4 stroke engine crankshafts. Both experimental and computational was carried out to determine the modal parameter or dynamic characteristics which are natural frequency, damping factor and mode shape. The(More)
In this paper, we are proposing a detection scheme known as spectral direct detection technique implemented with fiber bragg grating (FBG) act as encoder/decoder. This FBG based is used to encode and decode the spectral amplitude coding namely modified double weight (MDW) code in optical code division multiple access (OCDMA). This code is used due to its(More)
This paper describes the stress analysis for the corrosion area at the hollow pipe crane structure. This crane is used for lifting the load. Finite element analysis was used to investigate the stress concentration at the corrosion point. Three stages had been simulated; first stage simulates the structure without corrosion, second stage simulates the main(More)
Finite element models were developed to virtually carry out laser-micromachining of MEMS components. Four different MEMS components – micro-bridge, microcantilever array, micro-mirror and micro-comewere considered in the virtual work. Heat flux propagation and temperature plots generated by virtual lasermicromachining were compared and discussed. The(More)
