  • Dynamic Behavior of the Bumpy Road Shaking Table System

    Vibration tests were performed on the “bumpy road shaking table” system at the Cambridge University Geotechnical Centrifuge to investigate its dynamic behavior under operating conditions. In these tests, steel plates of known weights were fastened onto the base of the model container. The container was then subjected to “earthquake motions” simulated by the shaking table system and the ...

  • Vibration testing of a carbon composite fuselage

    This paper describes the details of an experimental investigation focusing on the vibration characteristics of a composite fuselage structure of an ultralight unmanned aerial vehicle (UAV). The UAV has a total empty weight of 70.3 kg and 6.3 m in length. The fuselage structure consists of the fuselage body with an integrated vertical stabiliser. All structural components are fabricated from ...

  • Crack identification in a cantilever beam using rotational laser vibrometer–based coupled of bending, axial and torsional vibrations

    In this paper, coupled response measurements are suggested for detection of a transverse surface crack in a cantilever beam. The crack has been modelled by a local compliance matrix of six degrees of freedom and simulated for detection. The eigenfrequencies are obtained using finite element method (FEM) and are compared with those of experiments. However, the small changes in eigenfrequencies are ...

  • Forget big data! Collect the right data

    The term big data is everywhere nowadays, but what does it actually mean? According to a definition provided by Google, big data is ‘extremely large data sets that may be analysed computationally to reveal patterns, trends, and associations.’ Sounds great, right? In theory, yes. Through big data, businesses can have a greater overview of their operations than ever before, allowing ...

  • Should Your Sensor Have A Connector Or Pin Terminals?

    When it comes to measuring the activity of your project, it’s nice to have options. High precision sensors can offer plenty of selections from the range of your measurements to the output of your readings, but a sensor is only as good at its connection. Connectors and pin terminals are common and dependable connections that relay your readings from within the sensor to the screen in front ...

  • Laying a Foundation (1947-1950)

    By 1947, the Hastings Instrument Company could count many successful projects.  Their list of products included the following: Raydist Navigation System Magnetic Switch and Coil Maximum Recording Accelerometer Visibility Meter While the list of projects was impressive, the company wanted to grow their profits further. Charles Hastings decided to ...

  • Opening the envelope on bearing vibration

    A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause ...

  • Planning for shake down

    Design improvements at operating power plants continue to challenge plant staff and original equipment manufacturers (OEMs). While basic design calculations consider the capacity of components and stresses resulting from their use, few consider vibration issues in great detail in the design. Vibration can lead to instrumentation failure, cracking and fatigue damage, or early degradation of the ...

  • Firmness evaluation of melon using its vibration characteristic and finite element analysis

    Analysis of the vibration responses of a fruit has been suggested as a non-destructive measure of its elastic properties (firmness). In this study, 'Huang gua' melons were excited using three types of balls (wooden, steel and rubber) and the vibration was detected by an accelerometer. The modulus of elasticity of the inner, middle and outer portions of melon flesh were determined using flat plate ...
