Abstract

Last forty years there is tremendous improvement in machining and development in technology. With increase in competition in market and to realize high accuracy, currently the non-conventional machining is becoming lifeline of any trade. One amongst the foremost necessity, the non-conventional machines like CNC Plasma flame Machins increase its demand in market due to high accuracy, finishing, and ability of machining any arduous materials. In this paper literature has been studied in the context to parametric optimization of CNC Plasma flame Machining. Different steel materials were used for experiment purpose. The various parameters were is taken for the analysis to find out optimized specification parameter such as cutting speed, gas pressure and air gap. The experimentation has been done to seek out the optimum parameters like cutting dimension, surface roughness value & amount of material removed as well as wear of nozzle.

Abstract

Belt is an important and expensive part of the conveyor belt system. At the early seconds of the starting process, maximum belt stretch is found which causes sudden failures or enormous starting belt stress. These dynamic stresses are difficult to measure and their presence could therefore go undetected. The transient stretch in the belt is investigated for the actual belt conveyor during full load starting condition. Belt conveyor system is considered as the series of vibrating mass and this unit is a viscoelastic segment; equation of motion is developed through the approach of Lagrange to study this process. Simulation technique is used to observe transient dynamic quantities. Dynamic belt stretch is studied in terms of dislocation within the conjugative units of endless belt. Result indicates that the maximum dynamic stretch value is 1.7 percent of the total length of the belt which comprises standard values specified for system. Dynamic stretch analysis would reveal the actual behavior of dynamic belt stresses in the conveyor belt.

Abstract

Many industrial facilities, especially those in the chemical, oil & gas and petroleum industries, involve inherent risk in operations due to the processing of material which are hazardous in nature. It is therefore, necessary to precisely identify & analyze the hazards, its operability issues, associated risks and its consequences. Safety instrumented systems (SIS) are often used to reduce the risk associated with process or plant to the acceptable or tolerable level. The reliability of safety function(s) implemented through SIS is determined by the magnitude of risk reduction and is provided in terms of safety integrity level (SIL). The determination of SIL is the method of determining the risk reduction magnitude to safety instrumented function (SIF). There are several techniques used to establish SIL to SIF. These are qualitative, quantitative or mix of both, based on the application under consideration. Layer of protection analysis (LOPA) is one of the prevailing methods to determine the SIL. This paper aims to establish when, why and how to apply the LOPA to determine the safety integrity level (SIL) and finally reached to the conclusion that LOPA is one of the best method for determine the SIL.

Abstract

Effective vehicle toll operation can be greatly enhanced by efficient monitoring mechanism. This can be achieved through the deployment of an automated monitoring system at every vehicle toll point. This paper presents a modality for implementing a microcontroller based monitoring system for effective vehicle toll operations. The system consists of Arduino Mega 2560 microcontroller unit, two units of ultrasonic sensors MA40E7R and a unit of SIM 800L GSM/GPRS Module. Each unit of the ultrasonic sensor, positioned at the toll point, transmits ultrasonic pulses into the air and detects the reflected waves from a vehicular object. When the two units have detected reflected waves simultaneously, a protocol car Found is implemented in the microcontroller unit. Each time this protocol is implemented, the counting sequence of the microcontroller is increased by a step. For each increment, a time stamp and count sequence is recorded in the microcontroller's memory slot; and a protocol send DataOnline is implemented through the SIM 800L GSM/GPRS module simultaneously. Arrangement was made using a dedicated cloud facility for real-time archiving and monitoring of data generated by the ground station while testing was going on. The system's operational cycle ensures complete elimination of human bias and guarantees minimal systemic error thereby ensuring effective monitoring operation.

Abstract

This paper is an attempt to accomplish a performance analysis of the different control techniques on current spike reduction by means of magnetization level control in the primary winding on the medium frequency transformer based DC spot welding system. Current Spike reduction is an important factor to be considered while spot welding systems are concerned. The current control technique is a piecewise linear control technique that is inspired from the DC-DC converter control algorithms to register a novel current spike reduction method in the MFDC spot welding applications. The different controllers that were used for the current spike reduction by means of magnetization level control of the overall applications involve the hysteresis controller, Proportional Integral (PI) controller. Care is taken such that the current control technique would maintain a reduced current spike in the primary current of the transformer while it reduces the Total Harmonic Distortion. In this research, intelligent control system is introduced by using Adaptive Neuro Fuzzy Inference System (ANFIS). The performance of ANFIS controller is presented considering the parameters, percentage of current spike reduction, and THD. It is proved that current spikes are controlled successfully and has less THD than the above mentioned conventional controllers. Matlab/SimulinkTM based simulation is carried out for the MFDC with 220 KVA welding transformer in resistance spot welding systems.

Abstract

Recently, hybrid control systems are occupying the positions of conventional control techniques in the aircraft systems due to their several advantages. Stabilizing, Controlling, and Minimizing the overshoots of the present Aircraft system compared to earlier is quite a challenge. In order to meet the requirements of todays flight control system and also following the investigations of both control and aircraft communities, this paper concentrates on the application of optimal switching control techniques for the lateral flight dynamics of an aircraft control system. The proposed techniques are implemented using MATLAB/SIMULINK platform.

Abstract

In today's competitive market, every EPC company aims at building client's trust through each project it executes. One of the best ways to develop this trust is by putting yourself in client's shoe while working on revamp/ brown field projects, where the main intent of client is to safely use the existing facility, instruments, and installation as much as possible in order to reduce capital expenditure. This gives rise to the subject of adequacy check of inline/offline instrument, i.e evaluating if the existing inline/offline instrument shall work under new process conditions or not. This paper describes various steps involved for checking adequacy of existing orifice plates for Revamp / Brownfield projects. Since every project has a significant number of orifice plates, adequacy check of existing orifice is quite essential and can save a huge amount to client in terms of effort hours and installation cost, if existing plate is reused.
