  • 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 ...

  • Harmonic response analysis and research of bus body based on the modal shapes

    The finite element model of the bus body is built in ANSYS software, and the finite element model was validated by stress tests. The mode shapes and the natural frequencies of the bus body determine its dynamic response properties, such as the transmission of vibration from the engine. The modal analysis is performed by using the ANSYS. Through the preliminary analysis of the modal shape and ...

  • Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

    Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...

  • Multidisciplinary optimisation of a car component under NVH and weight constraints using RSM

    One of the important challenges in the auto industry is to reduce the mass of the vehicle while meeting structural performance requirements for crashworthiness, noise, vibration and harshness, etc. In this paper, a multidisciplinary optimisation of a car back-bonnet is investigated by using the response surface method. A car body is fully surface modelled in CATIA and meshed in software. Then, ...

  • Optimising the natural frequencies of a fan shroud in a powertrain cooling system with modal iteration method

    The durability of a fan shroud is determined by its vibration response to the road, which in turn is determined by its natural frequencies relative to the frequencies from road excitation. The objective of the current study is to develop an optimisation algorithm that increases a specific structure's natural frequency such that it separates itself from the main band of the road excitation. The ...

  • 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 ...
