Vibration Analysis of Cantilever Smart Structure by using Piezoelectric Smart Material

The field of smart structures and smart materials has been an emerging area of research for last few decades. A smart structure would be able to sense the vibration and generate a controlled actuation to it, so the vibration can be minimized. For this purpose, smart materials are used as actuators and sensors. In this paper, some literature review is given about smart structure and smart material. Piezoelectric material is used as smart material and cantilever beam is considered as a smart

AcceleDent Aura does not influence treatment duration or number of visits

Background: Many techniques and appliances claim to reduce orthodontic treatment time, one of which is micro-vibration applied by the AcceleDent Aura appliance. Objectives: The purpose of this study was to report compliance with AcceleDent Aura and to assess any effect on treatment duration, number of visits and bond failures. Methods: Forty Class II adolescent subjects were randomly assigned to use the AcceleDent Aura appliance or no AcceleDent Aura device during orthodontic treatment with

STUDY ON FEATURE SELECTION AND IDENTIFICATION METHOD OF TOOL WEAR STATES BASED ON SVM

This paper presents an on-line tool wear condition monitoring system for milling. The proposed system was developed taking the cost and performance in practice into account, in addition to a high success rate. The cutting vibration signal is obtained during the cutting process, and then extracting features using time-domain statistical and wavelet packet decomposition algorithms. It would result in two major disadvantages if creating a tool wear states identification model based on all

Dynamical analysis and controllers performance evaluation for single degree-of-freedom system

set γ design parameter ω natural frequency of the exciting force Vibration is a big problem in many engineering systems. Active control for vibrations is very important topic with a lot of applications and fiscal benefits. An SDOF spring mass damper system represents many engineering structures. For example, in facing road bump, the vibration in a car can be modeled using the SDOF system. Also, the SDOF system is easy to analyze. It is easier to develop complicated systems

Assessing steam locomotive dynamics and running safety by computer simulation

on mainline can be done safely and without influencing the operation of the railways. If the details of the dynamic interaction of the steam locomotive's components are examined with computerised calculations they show differences with the previous theories as the smaller components cannot be disregarded in some vibration modes. A particular narrow gauge steam locomotive Gr-319 was analyzed and it was found, that the locomotive exhibits large dynamic forces on the track, much larger than those
