“…Finite element analysis of the random vibration was carried out for the whole structure, and fatigue tests were conducted on the simplified bolt. The results showed that the theoretical analysis and experimental results were coincident, which proved the failure mechanism of the bolts [10]. Zhang proposed a method to predict the fatigue life of airborne equipment; it combines the finite element model of an airborne electrical control box, Miner's linear cumulative damage criterion, and the Gaussian-distribution Steinberg method to estimate the fatigue life of the electronic control box in three directions.…”

The frame of the cotton picker is exposed to complex and varying loads during its operation. Therefore, conducting research on the vibration characteristics of the frame is crucial. In this study, vibration tests were conducted on the main vibration sources in a cotton picker at several measuring points on the frame. An accelerometer sensor was utilized to collect the signals. Fourier analysis was applied to analyze the vibration sources, encompassing the excitation frequency and the vibration source-coupled excitation frequency. Modal tests were also conducted to validate the finite element model and determine the natural frequencies of the frame. The results showed that the natural frequencies of the frame, specifically the third-order, fourth-order, and sixth-order frequencies, were comparable to the vibration source-coupled excitation frequencies. To prevent frame resonance, the response surface method was used to optimize the frame. Based on the MOGA algorithm, scheme 4 was identified as the optimal design. Furthermore, fatigue life calculations were carried out to optimize the parts with short lifespans on the frame, thereby enhancing the working performance.

“…Many studies on bearing vibration analysis have been carried out, since operational safety and efficiency, together with environmental protection, is one of the challenges of the world's industry (McFadden and Smith 1984). Therefore, efforts are being made to meet this need through spectral vibration analysis [7,14]. The dynamic state of movement and the actual operating conditions are the major milestones in laboratory studies.…”

This work shows the results of the comparative study of characteristic frequencies in terms of Power Spectral Density (PSD) or RMS generated by a blower unit and the SKFNU322 bearing. Data is collected following ISO 10816, using Emonitor software and with speed values in RMS to avoid high and low frequency signal masking. Bearing failure is the main cause of operational shutdown in industrial sites. The difficulty of prediction is the type of breakage and the high number of variables involved. Monitoring and analysing all the variables of the SKFNU322 bearing and those of machine operation for 15 years allowed to develop a new predictive maintenance protocol. This method makes it possible to reduce from 6 control points to one, and to determine which of the 42 variables is the most incidental in the correct operation, so equipment performance and efficiency is improved, contributing to increased economic profitability. The tests were carried out on a 500 kW unit of power and It was shown that the rotation of the equipment itself caused the most generating variable of vibrational energy.

“…The fracture of bolts can be classified into overload, fatigue, and delayed fracture [6]. The fracture of axial-connected bolts of the thin-walled cylinder [7] is a typical case of fracture. Overload fracture occurs when the bolt is subjected to excessive load or deformation, this kind of fracture will be disastrous in the high-rise or long-span structures.…”
