Engine Sound Evaluation by Audio Replay and Filtering

Engine Sound Evaluation by Audio Replay and Filtering

When we move to engine sound and vibration evaluation, we will have more methods and approaches that can be used to troubleshoot or improve the sound characteristics. In many cases, engine is considered as source of the vibration and sound. The fact that sound can be transferred through structure borne, air borne, or liquid borne makes acoustic/sound analysis becomes more challenging.

REMOTE CONTROL, the ultimate convenience technology to address COVID-19 pandemic concerns and demographic workforce pressures

In today’s business landscape, in order to survive this COVID-19 situation, plant owners/operators are looking for ways to change how they work. They are looking at the latest form of compact-equipment technology: remote control. For example, do you know what do bicycle helmets, toilet seats, and military drones have in common? Well, all three can be better and easier to use using remote control technology.

Vibration Testing System, Bringing the Actual Vibration Environment into Laboratory Scale Test

Vibration Testing System, Bringing the Actual Vibration Environment into Laboratory Scale Test

If our product is part of vital system in automotive where development time is getting shorter and crucial, or part of vital system in aerospace where prototype cost is relatively expensive and where safety has become very big issue, then having a vibration testing system may be considered as vital investment.

Monitoring the Health of Our Critical Machines Remotely, Why Not?

Monitoring the Health of Our Critical Machines Remotely, Why Not?

Remote monitoring for health of the machines has been developed for many years. Thanks to the rapid development of Information and Communication Technology (ICT), the health condition of rotating machinery is allowed to be monitored and analysed remotely from miles away, and even from our home. Not just remotely, the monitoring can even be done continuously.

Vibration Testing for Aerospace Payload_NASA-STD-7002B

Vibration Testing for Aerospace Payload_NASA-STD-7002B

National Aeronautics and Space Administration (NASA) is one of the most well-known aerospace agencies in the world. Therefore, NASA standards are also used as reference for testing laboratory to run testing related to component or sub-system of a spacecraft. NASA-STD-7002B is part of NASA standard that provides a standard set of flight hardware test requirements.

Electric Vehicles Battery Testing

Electric Vehicles Battery Testing

The global population of Electric Vehicle have been significantly increased within the latest few years. All major automakers recognize that the shift from fossil-fueled cars to EV is inevitable, and are investing accordingly. BATTERY, as one of the most CRITICAL part of electric vehicle is also having significant development period in order to fulfill the requirement from Electric Vehicle manufacturer.

Calibration of Vibration Controller

Calibration of Vibration Controller

To run a vibration testing, we need to set our test specification at the vibration control software and let the vibration controller to control the rest. A feedback sensor will send feedback signal. And based on this feedback signal, vibration controller will adjust the drive signal to make the actual vibration signal aligned with the test specification. Looking at how this system works, it is clear that the vibration controller is playing a very important part to accuracy of the vibration testing.

Vibration Controller, The Brain of Vibration Testing System

Vibration Controller, The Brain of Vibration Testing System

While accelerometer is playing the role of feedback sensor at vibration testing system, then vibration controller can be considered as the "brain" of it. Vibration controller is the device that sending the "instruction" in the form of drive voltage during vibration testing, and also interpreting the feedback signal coming from the accelerometer.

Condition Monitoring System, from Data Collection to Defect Diagnosis

Condition Monitoring System, from Data Collection to Defect Diagnosis

When we have large size of rotating machinery, performing corrective or preventive maintenance may not be so easy anymore. Based on the periodicity of the data collection, machine health condition monitoring can be classified into below categories: 1. Periodical Monitoring; 2. Semi-Online Monitoring; 3. Real Time Monitoring

Shortening the Design Process of Vibration Test Fixture by FEM Simulation

Shortening the Design Process of Vibration Test Fixture by FEM Simulation

When we have a relatively small size and simple shape of UUT, with a simple mounting pattern, simple product orientation and low frequency test range, it will not be so tough to design a good vibration test fixture. But when we start to see one or more of below characteristics, then likely we will find designing vibration test fixture to be very challenging.

Accelerometer Calibration, Ensuring Accuracy of Vibration Testing and Measurement

Accelerometer Calibration, Ensuring Accuracy of Vibration Testing and Measurement

These are most common questions raised by test engineer during training session after the installation of new vibration testing systems. But before going to more details regarding accelerometer calibration, it is better to understand what role is played by accelerometer during vibration testing.

Vibration Test Fixture, Not Just an Adapter for UUT

Vibration Test Fixture, Not Just an Adapter for UUT

What is a Vibration Test Fixture? Looking at its appearance, vibration test fixture is needed for mounting our Unit Under Test (UUT) to the Vibration Testing machine. Is that it? Unfortunately, not that so straight forward. For some engineer, vibration test fixture may be considered just like an adapter. As long as the UUT can be mounted to vibration machine platform, then it is good enough. But for test engineer with experience, designing a vibration test fixture may be quite challenging as well.

Vibration Signal Post Processing, One Step Further to Valid Vibration Test

If you are a test engineer and you plan to perform vibration testing on your product, you already collected data from actual vibration environment. Then, what you need to perform next will be Signal Post Processing

Which type of vibration test need to be used? Should I do Sine? Why not Random? Or Shock?

Which type of vibration test need to be used? Should I do Sine? Why not Random? Or Shock?

For some test engineers, this question may not be so relevant, since some vibration test are done by following certain test standard. But there are some cases, can be in automotive, aerospace, defence, or even railway, when test engineers need to tailor their own specific test procedure.
