Special Concrete with Polymers

Abstract

The development of polymeric materials offers new perspectives of science and technology due to their outstanding properties. These properties are obtained either due to the effect of dispersion polymers and their polymerization either due to their intervention in structure formation. They were prepared epoxy resin polymer concrete, Portland cement, coarse and fine aggregate and to evaluate the influence of resin dosage on microstructures and density of such structures reinforced concrete mixtures. The paper detailing the raw materials used in experimental works and structural properties of concrete studied.

Experimental Results of Vibroacoustic Diagnosis Performed with Vibro-Expert System

Abstract

The implementation of proactive maintenance is a necessity required by the development of modern technologies for the monitoring and exploitation of energy facilities and equipment. An important advantage of proactive maintenance is to permanently monitor the technical condition of the plant and equipment by vibration measurements and in the correct diagnosis in order to reasonably plan the required repairs. Turbo-aggregates are autonomous complex installations for producing electricity in refineries that operate in high power and high-speed modes. To monitor and control turbine vibrations, vibration sensors (uniaxial, biaxial and triaxial accelerometers) and proximity sensors (for relative displacements and lasers) are columned on bearing housings that transmit signals to data acquisition and processing systems as well is the Vibro-Expret diagnosis system presented in this paper.

Methods of Determining Sock Values and the Distance Between Axes of the Gearboxteething Using a Fitted Tooth Engagement

Abstract

There are several constructive variants of devices built for complex control of engagement on both sides aimed at controlling both internal and external shocks, all of which featuring a standard wheel compound. By the method of forced tooth engagement fitted between the standard wheel and the measuring wheel and using the spectral analysis, constructive errors of the gear wheels can be quickly determined, especially those consisting in shocks and the variation of the distance between the axes, errors that severely impact on operation. At the National Institute of Research and Development in Mechatronics and Measurement Technique was developed a device used to control shock values and the distance between the axis of the gearboxes (for four of the gearbox speeds) by means of forced engagement and complex harmonic analysis.

New Measurements Results Achieve for Proactive Maintenace with Vibro-Expert Diagnosis System

Abstract

One important objectives of proactive maintenance are the knowledge of the technical state of machinery, the intelligent planning of interventions according to the diagnosis technique, identification and correction of assembling errors. The aim of this paper is to present a new case on the vibrations diagnosis of hydro-aggregate CAMPELA - CHE Dubasari (MOLDOVA). The VIBRO EXPERT diagnostic system used on the CAPMELA hydro-aggregate is designed to measure, monitor, diagnose, and analyze the technical and functional parameters in order to safe use of the hydro-aggregate turbine, using the vibrations data measurement. The proactive maintenance concept is being used more and more thanks to the development of these intelligent monitoring and control systems, in order to prevent interruptions due to major failures.

Intelligent Platform with BLDC Drives and Microsystems for Mechatronic Applications in Security and Surveillance

Abstract

Result of the Scientific Concerns from the Doctoral School of Mechanical Engineering and Mechatronics of the Valahia Târgovişte University and the research project of INCDMTM “INTEGRATED MECHATRONIC SYSTEM FOR HUMAN SECURITY INSURANCE FOR THE SAFETY OF OBJECTIVES AND INTERVENTIONS IN RISK - MISO ZONES” (project ID: PED-2016-0924, code PN-III-P2-2.1-PED-2016-0707) in the field of robotics, the scientific work “Intelligent Platform with BLDC Drives and Microsystems for Mechatronic Applications in Security and Surveillance “ is the completion of the experimental testing of controlling the movement of a security and surveillance robot, as part of the Ph.D. industrial thesis “Studies, research and contributions on the development of a smart mecatronic robot for security and surveillance applications”. The scientific work ultimately results in an intelligent, original platform that will be used to control the movement of the robot. The platform allows communication between the latest generation BLDC engine (embedded in the drive wheel) and it’s controller and a computerized microsystem that will handle the displacement controls and will also provide the link with the human operator through any remote guidance system that is used. Although designed for an intelligent security and surveillance mechatronic robot, this platform is proven to be extensively versatile for any other type of robot or mobile platform that uses BLDC wheel-drive engines. The project harmoniously combines Mechatronics, Cyber-MixMeatronic, Integronics and Artificial Intelligence into an Intelligent Interoperable Construction.

Intelligent 3D Video-Laser System for Measuring Distance and Avoidance of Obstruct Obstacles Integrable Into Robotic Platforms

Abstract

Outcome of the scientific concerns from the Doctoral School of Mechanical Engineering and Mechatronics at Valahia University of Târgovişte in the field of unconventional measurements using non-contact laser technique, the scientific work “Intelligent 3D video-laser system for measuring distance and avoidance of obstruct obstacles integrable into robotic platforms” is a work in progress being in the experimental phase of single-channel testing. The system is designed for robotic platforms for special interventions in high-risk work environments, with the main goal of an active, real-time 3D spatial stereo interface for the operator who manages the robotic platform remotely. 3D imaging and real-time measurements of distances provide the operator of the robotic intervention platform with the ability to perform extremely precise maneuvers. The scientific work ultimately results in an intelligent integral system that can predict the emergence of an obstacle to the robotic platform movement, thus determining the distance in real time to it. The measuring distance is between 0 m - 40 m, with an accuracy of +/−0.5 cm being synchronized with the video system with a clear visual area from 0.05 m to infinity. The 3D video laser system can simultaneously shoot movie or single images of the obstacle, storing data in 3D, photo or video digital formats, both locally in non-volatile memory or externally thru any GPSR network to the operator and / or to a control center. In later development, the measurement system will be coupled to a GPS network for auto location of position and architected with a self-defense and offensive module mounted on the mobile robotic platform. Thus, this complex project combines in a unified knowledge of Mechatronics, Integronics, Cyber-Mix Mechatronics, Artificial Intelligence and Information Technology.
