  • 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 ...

  • Controlling combustion noise in direct injection diesel engine through mechanical vibration measurement

    The next generations of direct injection diesel engines have greatly improved their performances compared with petrol engines. However, one of the pending subjects is the noise and vibration levels, due to working cycle itself. The design effort to reduce the emissions of noise and vibration transmitted to the vehicle's driver could be lessened because of the assembly process variation. In this ...

  • Maintenance tips for cooling towers - White Paper

    Cooling towers are prone to the typical causes of rotating machine failure such as misalignment, but also face a range of specific environmental challenges, including high or gusting wind speeds, dust, sand and, in coastal locations, high concentrations of salt. In the 1990s, for example, vibration and accelerated wear caused a fan blade to shear off a cooling tower in Pennsylvania, ...

  • Controlling the timing chain noise in diesel engines

    Timing drive by chain is commonly used in passenger cars especially in diesel engines with double overhead camshafts owing to their numerous advantages compared with belt drive systems. However, one of the important subjects to take into account is the timing chain noise, so-called "meshing noise" that can be perceived by the driver. The manufacturer's efforts to reduce it, are focused ...

  • Controlling the turbocharger whistling noise in diesel engines

    Turbochargers are now commonly used in passenger cars especially in application with diesel engines because of their numerous advantages. The use of this machine greatly improves engine performance, while at the same time allowing pollutant emissions to be reduced. However, one of the important issues to take into account when a turbocharger is used in passenger cars is the whistling noise due to ...

  • Brüel & Kjær expands - support of I-deas test products

    In October 2005, MTS Corporation decided to withdraw from the noise and vibration (NVH) market. Maya HTT and Brüel & Kjær are, therefore, pleased to announce that the new partnership is committed to continuing the sales and support of I-deas Test and related software products for noise and vibration analysis. New and existing customers alike can, therefore, use Brüel & ...

  • Interview with John O`Higgins, chief executive of Spectris

    Environmental issues - a growing concern among organisations Presently, organisations are seriously contemplating environmental issues and are taking necessary steps towards improving their products and processes. Large companies are now focusing on reducing their carbon footprint and ensuring that their products are environment-friendly. Even in niche segments, organisations are ...

  • What are the root causes of wear in industrial machinery?

    Over the years we’ve published a wide range of material designed to help you protect your assets and prevent machine failure, through implementing the right maintenance programme and taking appropriate action to fix issues before they manifest into larger and often more complex problems. However, ...

  • Introduction to the BioCar Nature Based Transportation Systems

    The people of the world are rapidly growing aware of the full impact of current transport systems upon their safety, economy, health and environment. This has not been lost on the major auto companies who have spent millions of man-hours and billions of dollars over the last decade in pursuit of the Next Generation Vehicle. But they have little to show for their efforts having been increasingly ...


  • Distributed Measurements Unlock the Future of Design

    The next generations of materials and design will require sensing technologies that can monitor beyond the scope of point sensors such as thermocouples and strain gauges. New sensing platforms based on optical fibers can obtain spatially continuous, real time data, giving developers detailed insight across broad areas into how their materials and designs behave. Such systems also can sense ...
