To develop, improve, certify, or troubleshoot a product, physical testing is required either on a test bench or in the field. Usually, the more complex or larger the product, the more measurements are required.
Over the last 25 years, Finite Element Analysis (FEA) has become more powerful, accessible, and affordable. But the need for physical vibration testing has remained, for correlation, verification, package testing or final acceptance.
Fundamentally, any rotating shaft has the function of transferring power, i.e. the product of the rotational speed by the transferred torque.
As decarbonisation of society slowly takes place, so does electrification of various equipment. On fixed plants for example, small steam turbines driving pumps or fans are regularly replaced by motors. In the automotive industry, the transition is faster with the number of hybrid and electric vehicles now rapidly increasing.
In a market with a lot of options, HBK (formerly Bruel and Kjaer) acoustic cameras are a beacon of precision and efficiency.
Most sensors are transducers, converting the physical quantity to measure into a generated output to digitalise. For decades, the generated output has been electrical in natures, therefore the name “electrical sensors”.
Vibration test systems, also called shakers, are used for laboratory testing, modal and structural analysis, squeak and rattle, package testing, and durability testing of objects of practically any size – ranging from small electrical components through to complete systems and large payloads.
In the era of electrification, many new challenges arise, such as the noise impacts of Battery Energy Storage Systems (BESS). BESS noise levels often consist of a significant amount of low-frequency noise (500Hz or less) with tonal components. Due to these factors, the environmental assessment of BESS would be more reflective of real-world conditions when undertaken using 1/3 octave band analysis.
The landscape of automotive testing is evolving, driven by the need for more accurate, efficient, and comprehensive evaluation methods. HBK (Hottinger Brüel & Kjær) have been leaders in this field for decades, offering integrated solutions that bridge the gap between virtual simulations and real-world testing.
In today’s rapidly evolving technological landscape, precise motion sensing is crucial for various applications, from industrial machinery and consumer electronics, to drones, aerospace, and defence . The concept of Six Degrees of Freedom (6DOF) sensors is a cornerstone in this field, providing comprehensive motion tracking by measuring translational and rotational movements across three perpendicular axes.
You already know why users love the HBK QuantumX Data Acquisition System and its ruggedised cousin; the SomatXR?
Monitoring complex gearboxes can be quite a challenge, especially for multi-stage planetary gearbox setups. A lot of noise occurs within your data due to the many gear meshes, which makes it hard to identify bearing and gear faults accurately and when data is only taken on a routine basis, these faults can easily be missed.
Instrumentation is arguably a discipline where the diversity of physical phenomena is used to deliver optimal engineering solutions. Many sensors are electrical by design: strain gauges, piezo-electric accelerometers, piezo-resistive sensors, etc.
In practical terms, TEDS allow you to plug your sensor in a data acquisition system (SomatXR, QuantumX, LAN-XI, PMX, ClipX, etc.) and to start your test and measurement tasks immediately.
NVMS’s highly-regarded Noise Assessor Course is coming to Brisbane next week, and with a couple of places still available it’s not too late to register. We’re also seeking expressions of interest to bring the course to Melbourne in 2025.
