What is Kurtosis?
Kurtosis is a parameter of any signal, which represents its “peakedness”. But what makes this parameter so important for vibration testing and data analysis? And how can you manipulate it in RULA software? Let’s find out.
What is Vibration Testing and Why Do We Need It?
We are constantly surrounded by vibrations, some of which are less welcome than others. Many products of automotive, aerospace, electronics, and other industries are subject to intense vibration impact that can cause severe damage to the moving parts. This in turn might break the equipment, or even endanger the life of your customers.
Preventing the damage caused by vibrations is the goal of vibration testing. In today's article, we will take an overview of this field and see how RULA can help you optimize the testing process.
What is Fatigue Damage Spectrum?
Field Data Replication (FDR) offers a way to simulate real-life conditions with a high degree of accuracy. However, FDR has a major drawback — should we want to test an object up to destruction, the tests can take a very long time. Fatigue Damage Spectrum (FDS) option in RULA Software solves this problem, greatly reducing test time and offering much more flexibility in regard to signal duration. Read more about FDS in our article.
Multishaker Tests with RL-C21 and RL-C25: Theory and Application
Multishaker testing has become a popular method for testing large objects, which you cannot place on one shaker, or for simultaneous vibration impact on the object on several axes. In today's article, we will look at how to set up multishaker tests using our vibration controllers RL-C21 and RL-C25.

How to Mount Accelerometers
The first step to ensure that your sensor is giving accurate data is to correctly mount it on the surface. In this article, we will take a look at the most used mounting methods and give you useful tips that will help you choose the one that suits your needs.
Modbus TCP: How to Get Data from Climatic Chambers and Power Amplifiers
Complex environmental tests combining vibration and climatic impact are becoming a trend in the testing industry. RULA Technologies provide a convenient tool for running such tests with RL-C21 and RL-C25-series controllers. Learn more in our todays's article.
Notching Control and Why You Should Use It
Imagine you are testing a satellite with solar panels. It is crucial to prevent the destruction of solar panels due to resonances during the test. Notching is a tool that helps you avoid all resonances on a particular frequency by limiting the acceleration values.
How to Calibrate Microphones
Microphones need to be calibrated to ensure they stay "healthy" and perform at their maximum capacity. RULA engineers have developed and algorithm that allows you to easily calibrate a microphone using sound pressure — a topic of our today's article.
Setting Additional Shock Limits
Setting Shock limits is the main way to prevent equipment failures and breakages. Learn how to configure the shock limits in RULA Software in our today's article.
Accelerometer calibration: a step-by-step guide
Sensor calibration is a procedure that ensures the safety and maximum performance of your sensor. Ideally, it should be performed once a year. How do you automate accelerometer calibration using RULA Software? Find out in our article.
