Measuring Interior Electric Vehicle Noise Using Octave Analysis

Measuring Interior Electric Vehicle Noise Using Octave Analysis

The interior noise of a vehicle has a significant impact on the customer experience. Any noise outside the norm can raise concerns and discredit the company’s reputation. Engineers have a solid understanding of the noise requirements for internal combustion engine (ICE) vehicles, but electric vehicles (EV) require new standards. As EVs do not have an engine that makes noise, many normal vehicle disturbances are now audible to the passenger.

Drop Shock Testing for Products and Packaging

Drop Shock Testing for Products and Packaging

Many products will experience shock vibration during shipping and handling or in use. These shocks may be infrequent, such as an accidental drop or repetitive, as with transportation over rough road conditions. Vibration test engineers use shock testing to simulate these conditions in the lab and confirm the structural integrity of the device.

Types of Vibration Control

Types of Vibration Control

Vibration Research designs and manufactures leading edge vibration control systems for all brands of electrodynamic and servohydraulic shakers, as well as portable dynamic signal analyzers. Vibration control systems include hardware vibration controllers and the vibration control software, providing a multi-point control of complex structures, all with an intuitive user interface and easy setup.

Tips or guidance to consider before buying and operating a vibration shaker

Tips or guidance to consider before buying and operating a vibration shaker

In order to choose the right shaker, there are a few major specifications to consider such as frequency range and waveform, displacement and velocity, the number of axes to be tested, payloads and vibration/shock levels, and force rating.

SRS - Shock Response Spectrum

SRS - Shock Response Spectrum

The SRS is commonly used to characterize the frequency content of an acceleration time-history record. Shock response spectrum analysis is the maximum response of a series of single degree of freedom systems having the same damping to a given transient signal.

How to choose the right packaging testing methods – Shock Testing

How to choose the right packaging testing methods – Shock Testing

If you’re designing the packaging for a new product or a rebranding, you probably want to know how safe your goods will be and how customers will react to your packaging before you invest in a final design. With packaging testing, you can both satisfy consumer sentiment and choose the right packaging design for your product from the safety point of view.

Batteries in Electric Vehicles, How Long Do They Last?

Batteries in Electric Vehicles, How Long Do They Last?

While it is true that electric cars lose battery capacity over time. The continuing advances in technology in precise degradation are difficult to define as a whole. The main factor is all down to the owner and how they treat the battery. The way energy is added, the way it is removed. And how many charging cycles, the battery experiences look after your battery and your battery will look after you.

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.

Shock Test, From Classical to Shock Response Spectrum (SRS)

Shock Test, From Classical to Shock Response Spectrum (SRS)

IEC60068-2-27 mentions that the purpose of having shock test is to reveal mechanical weakness and/or degradation in specified performances, or accumulated damage or degradation caused by shocks. It may be used in some cases to determine the structural integrity of specimens.

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.

Reliability is the key

The accuracy of all measuring devices degrades over time. This is typically caused by normal wear and tear. Depending on the type of the instrument and the environment in which it is being used, it may degrade very quickly or over a long period of time. Calibration improves the accuracy of the measuring device and the accurate measuring devices improve product quality.

Managing the accuracy of your measuring devices is an important job, often leading the technicians and engineers to ask “How often should I recalibrate my accelerometers, controllers or vibration meters?”

As a team of vibration test and measurement experts, we understand the frustrations of a test that results are unexpected or unreliable data, a sensor that has passed its calibration date or even worse, realizing necessary measuring devices are out for calibration.

ETS Solutions offers precise and efficient accelerometer and controller calibration, with very short turn around time, 3 days for Singapore market, bringing control and confidence to your process. We take care of your instrumentation while you focus on your own product development.

Being able to demonstrate that your equipment has been calibrated per ISO17025 standard, offers a significant payback and peace of mind, as your measuring devices are all accurate.

ETS Solutions is offering a broad frequency range from 5 Hz to 20 kHz accelerometer calibration, controller calibration, vibration meter calibration as well as data loggers calibration.
