When some of the test engineers try to run vibration test to simulate the actual vibration experience, they may experience a situation when they think their vibration test result is not valid. Why is it not valid? One simple answer, because the test procedure is unable to re-produce the same failure mode.
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.
Products are vibration tested to determine limits and tolerances. Every product is vulnerable to vibration loads and potential breakage or failure. That includes tiny objects like microprocessors and circuit boards right up to giant structures like bridges and skyscrapers.
Vibration testing allows designers, engineers and manufacturers to know what stress limits their product can withstand.
Testing through vibrations ensures the product is qualified for its intended purpose and meets safety and regulatory standards, as well as complies with any International Standards Organization (ISO) requirements. Part of due diligence in vibration testing determines fatigue testing, failure limits and structural integrity screening.
Many industries routinely use vibration testing as part of their quality control program. Finding out what vibrations a product withstands before release makes good business sense. Known limitations allow the end user to employ their product safely and put it into trouble-free service.
Testing for vibration resistance prevents product recall, supports warranty conditions and provides excellent product purchase value.
With more than five decades of expertise in the business, we’ve created our own line of efficient instruments and tools to alleviate the need of several industries that include aerospace, defence, automotive, consumer electronics, locomotive, construction and more.

Electric vehicles are clearly becoming an expanding part of the automotive scene, assuring low or no emissions, conceivably low cost of fuel from the power grid, yet they will continue to drop us safely from a place to another. However, electric vehicle design and manufacturing is a clearly paradigm shift for the Automotive Industry: new technologies, new drive systems and test plans.
Electric vehicles are bringing new test and validation challenges to the automotive industry as the electronic and software content of the vehicles increase. The battery packs used as the rechargeable electrical storage system in electric vehicles (EVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs) are big and complex. Controlled release of the battery’s energy gives useful electrical power in the form of current and voltage. Uncontrolled release of this energy can cause dangerous situations such as fire, release of toxic materials (i.e. smoke), explosions, or any combination thereof. Uncontrolled energy releases can be generated by severe physical abuse, such as crushing, puncturing or burning, which can be mitigated by mechanical safety systems and proper physical design. Nonetheless, they can also be caused by abnormally high discharge rate, shorted cells, excessive heat buildup, overcharging, or constant recharging, which can weaken the battery. One of the major validation and safety challenges to begin with in modern EVs, HEVs, and PHEVs concerns the effective testing of the battery pack itself and the Battery Management Systems (BMS) – the complex electronic system that manages the performance and safety of the battery pack and the high levels of electrical energy stored within.
Battery pack designs for electric vehicles are complex and vary widely by manufacturer and specific application but they all cover combinations of several simple mechanical and electrical component systems which perform the basic required functions of the pack.
Developing a test strategy for an assembly as complex, big and powerful as an electric vehicle battery pack can be a daunting task. Breaking the process down into manageable pieces is the key to find a solution, like in most complex problems. During the battery management systems development, engineers need a way to reliably test the system under real-world conditions to complete their verification and validation plans. Testing involves simulating physical inputs and external digital connections to the pack while monitoring its outputs and behavior relative to design requirements. It is not easy to accurately simulate all of the real-world conditions a battery management system will be subjected to. But in the end, simulating nearly every combination of cell voltages, temperatures, and currents you expect your batteries to encounter is really the only way to verify that your system reacts as you intended in order to keep your pack safe and reliable.
At the pack development stage, engineers are mostly concerned about testing the entire assembly through various types of environmental stress testing as part of design validation or product validation plans. Environmental stress could include exposure to temperature extremes, thermal shock cycling, vibration, humidity, on-off cycling, charge discharge cycling, or any combination of these. The testing requirements here typically include performing a full batch of performance tests on a pack both before and after application of the stress. Live monitoring of the pack throughout the environmental stress period may also be required.
