We have learned, and we will teach you

BOT4.AI specialists have elected to leverage their expertise to analyze vibrations. The direction (vertical, horizontal, or axial), source, and intensity of the vibration can indicate potential issues, such as failures, challenges, or injuries.

For instance, if a shaft is supported by four bearings and one of them does not vibrate in the same manner as the others, this may result in the shaft failing. Furthermore, if the bearing in question is part of the machine, its failure can result in significant operational issues. If vibration analysis specialists detect the problem in a timely manner, they can implement a solution or prevent it from occurring altogether. Otherwise, there is a risk of breakdowns and other situations that could have been avoided. Our BOT4.AI and design departments participated in a high-cycle fatigue test on a statically installed piece of equipment. Upon reaching the specified resonance peak, the device began to oscillate. This enabled our team to extract all the necessary information (please contact hello@bot4.ai for further details).
The high cycle fatigue (HCF) test involves cyclic loading at maximum speed, resulting in small (shallow) deformations or cracks. Engineers conduct this qualification test on components such as turbine blades to model challenging operating conditions. Consider the possibility of simulating an airplane flight in various climatic conditions or with different lateral wind loads. BOT4.AI specialists employ sinusoidal resonance, tracking, and delay (SRTD) to control HCF tests. We conducted tests at various levels of acceleration and achieved positive results. Performance increased by thousands of times at each delay. During the test with reduced acceleration (g), we observed fluctuations after reaching the resonance peak. This verifies our assumptions and will be beneficial for the customer.

We have found that one of the causes of fluctuations can be the response time of the control system. The resonance does not respond immediately to the input, so if the control happens faster than the resonance has time to change, then fluctuations will occur.
Our analysis has identified the response time of the control system as a potential cause of fluctuations. Due to the resonance not responding immediately to the input, fluctuations may occur if the control occurs faster than the resonance has time to change. The client attempted to modify the input filter parameters and other settings, but this did not yield the desired results. In some instances, a specialist may be unable to adjust the response time due to the limitations of the test. It is possible to set up the correct feedback, but this requires special software settings (hello@bot4.ai). Our team has developed expertise in adjusting the control loop, which allows more comprehensive control of the system beyond resonance.
