ACTIVE SAFETY CONTROL TECHNIQUE TO PREVENT VEHICLE CRASHING Rupesh S. Bobade1 and Shrikant K. Yadav2 1,2Department of Mechanical Engineering, MIT College of Engineering, Pune, MH, India ABSTRACT Alertness during driving is a key aspect. Even a small distraction for the driver may lead to genuine mishaps. The possible reasons can be obstacle, inadequate vehicle control system or human reflexes (e.g. shock) during sudden distraction. Therefore "Active" and "Passive" systems for vehicle control play a significant role in automotive safety. In this paper, we have discussed an active control technique to prevent the vehicle from crashing. Three different cases of vehicle speed are considered. The presented technique is designed to evaluate the possibility of collision for both front and rear side. The control action will be taken for safe and smooth driving under different situations like parking, urban driving and highway driving. KEYWORDS: Active, Passive, Control system, Vehicle speed

Numerical Analysis of Engineered Steel Fibers as Shear Reinforcement in RC Beams

NUMERICAL ANALYSIS OF ENGINEERED STEEL FIBERS AS SHEAR REINFORCEMENT IN RC BEAMS J. Jeevitha1 and R. Venkatasubramani2 1P.G. Scholar, Dr. Mahalingam College of Engineering and Technology, Tamilnadu, India 2Head of the Department (Civil Engineering), Dr. Mahalingam College of Engineering and Technology, Tamilnadu, India ABSTRACT Using suitable fibers and additives in concrete to enhance its performance is an important consideration in the concrete industry with regard to the structural aspects of concrete. The purpose of this project is to investigate numerically the effectiveness of the engineered steel fiber as shear reinforcement in RC beams. Here steel fibers completely replaces the shear reinforcement (stirrups & links). The dimension of beam taken was 1000*150*150 mm with aspect ratio 80. The beams were reinforced with 10 mm steel bars as secondary reinforcement and 12 mm bars as main reinforcement on the tension side. Numerical analysis using ANSYS R16.1 software package was carried out. The load-deflection curves for the beams with different dosage of fibers were drawn superimposing their numerical values. Initially, in all three cases the curve was linear elastic and about 80% of ultimate load they tend to be non-linear. It was observed that there was fair agreement between the results which indicates some favourable aspects concerning the use of steel fibres as shear reinforcement in concrete beams. It was investigated that the inclusion of steel fibres (Hook End Type) improves the shear strength of RC beams without stirrups by improving the matrix between concrete and steel fibers. Thus this project focuses in the design and analysis using the software ANSYS R16.1 for an alternative steel reinforcement with better or equivalent performance.

TRANSIENT ANALYSIS OF PIEZOLAMINATED COMPOSITE PLATES USING HSDT P. Ravikanth Raju1, J. Suresh Kumar2 1Anurag Group of Institutions, Venkatapur (V), Medchal. Dt, Telangana, India. 2JNTUH, Telangana, Hyderabad, India. ABSTRACT Piezoelectric materials have excellent sensing and actuating capabilities have made them the most practical smart materials to integrate with laminated structures. Integrated structure system can be called a smart structure because of its ability to perform self-diagnosis and quick adaption to environment changes. An analytical procedure has been developed in the work based on higher order shear deformation theory subjected to electromechanical loading for investigating transient characteristics of smart material plates. For analysis two displacement models are to be considered i.e., model-1 accounts for strain in thickness direction is zero whereas in model-2 in-plane displacements are expanded as cubic functions of the thickness coordinate. Navier’s technique has been adopted for obtaining solutions of anti-symmetric cross–ply and angle-ply laminates of both model-1 and model-2 with simply supported boundary conditions. For obtaining transient response of a laminated composite plate attached with piezoelectric layer Newmark’s method has been used. Effect of thickness coordinate of composite laminated plates attached with piezoelectric layer subjected to electromechanical loadings is studied. KEYWORDS: Anti-symmetric, electromechanical, piezoelectric layer, Navier’s technique, Newmark’s method, smart materials.

The majority of Brazilian small craft fishing fleet comes from artisanal boatyards which struggles with market pressure, professional social devaluation, and lack of raw materials. This work aims to provide a description about small craft artisanal boatbuilding in Brazilian shores to support initiatives to increase its social, economical, and environmental sustainability. On site visits and interviews about craftsmen social-economics; boatyards’ production organization; and manufacturing processes’ technological aspects were conducted. Results show that craftsmen are characterized by reasonable income and livelihood degree, compared with workers of similar educational level in their region. Relationships and work organization among them is traditionally structured and community based. Boatyards have sufficient structure, though access to new technologies and resources could be increased. Observed plank on frame building technique depends on workforce skills, commitment, and knowledge, as well as the resulting boats’ design and performance. Small craft artisanal boatbuilding is a living sector with its own dynamics, subjected to the creation and eventual adoption of new technologies. Instead of replacing the current manufacturing process by fibreglass reinforced polymer laminates, as suggested by some initiatives, it is believed that this sector’s sustainability can be increased by gradual introduction of tools, materials, and techniques while preserving its artisanal characteristics and qualities.

Keywords: Small craft design; artisanal boatbuilding; woodworking; fishing fleets.

This paper present the impacts of power quality issues namely harmonic distortion, transient  in electrical system due to Variable Frequency Drives (VFD) known as Power Drive system (PDS) and its elimination techniques is investigated both side at the  Point of Common Coupling (PCC) and input side of motor. The Harmonic measurements of electrical supply system and motor drive are done, with the help of Matlab software to determine whether a significant amount of harmonic in currents or voltages is presented. From these measurements and analysis,  the  impact  of  harmonics  is  analyzed  and  found  that  the  harmonic  content  of  electrical power system & motor  drives  to  be minimized by suitable strategies like Multi pulse converter or Active front end converter, within  the  limits  of  international  harmonic  standards like IEEE 519 and IEC. In  recently,  multi  pulse and multilevel  drive  solution  gained  an increased  attention  due  to  their  effective  harmonic  elimination which is implemented in Matlab/Simulink. Sinusoidal Pulse width modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) techniques are used to generate switching sequence for the multilevel inverter and a detailed harmonic study has been carried out.

Keywords— Variable Frequency Drives (VFD); Pulse Width Modulation (PWM); Sinusoidal pulse width modulation (SPWM); Space vector pulse width modulation (SVPWM); Induction Motor (IM); Point of common coupling (PCC); Power Drive System (PDS).
