“…To obtain basic data for developing a procedure for evaluating the structural performance of the VEH, we surveyed the existing studies on the structural performance evaluation procedure of traditional structures, which are designed to avoid resonance. We identified that most studies employed experimental or analytical methods [15][16][17]. For example, Zambrano et al [15] conducted a structural analysis of the axes of a bridge crane by applying chemical and structural properties and other measurements, such as hardness, to evaluate the structural integrity performance.…”

A vibration-based energy harvester (VEH) utilizes vibrations originated from various structures and specifically maximizes the displacement of its moving parts, using the resonance between the frequency of external vibration loads from the structure and the natural frequency of VEH to improve power production efficiency. This study presents the procedure to evaluate the structural performance and structural integrity of VEH utilized in a railway vehicle under frequency domain. First of all, a structural performance test was performed to identify the natural frequency and assess the structural response in frequency domain. Then, the static structural analysis was carried out using FE analysis to investigate the failure critical locations (FCLs) and effect of resonance. Finally, we conducted a frequency response analysis to identify the structural response and investigate the structural integrity in frequency domain. Based on these results, the authors assessed the structural performance and integrity of VEHs in two versions.

“…The second cracking was also observed in the second drill rod (right), as the ratchet marks appeared similar to [6]. Additionally, the presence of the beach and ratchet marks indicated high local stress [7]. Based on information of the drills used in the operation, the second drill rods were intensively operated within a shorter period of time (32 days) and relatively higher rate of drilling, comparing to the first drill rod.…”

Failure analysis of two hydraulic rotary drills used for rock drilling was carried out. Chemical analysis, metallurgical examination, surface fractography and hardness measurement were used for the analysis. The failed drill rods composition matched with low alloy 31NiCrMo13-4 grade steel. The hardness measurement results suggested that the drilled rods were surface hardened. Surface fractography examination revealed that crack initiation of the fractured drill rods started at the outer surface, especially at the joint between the drill rod and drill bit. The mode of failure was found to be fatigue. The stress concentration locating at groove of threads at the joint was likely to cause the crack initiation. Propagation of fracture was observed with the evidence of beach mark, resulting from continuous nominal low stress. 

“…For calculation purpose, it is necessary to select the type of support, apply loads, to generate diagrams of flexion, compression and torsion and evaluate the safety factors for critical section [2,3]. In order to know new conditions, the investigation includes the following objectives: analytical stress calculation, FEA stress calculation and comparing both results [4][5][6].…”

This paper describes the analysis of steel reel shaft as drive shaft in a process of umbilical spooling of wire rope. There is a need to investigate shaft behaviour in the conditions of increasing workload. The aim is to investigate avoiding possible redesign or enabling redesign with minimal costs. Stress analysis has been carried out by using finite element analysis (FEA) and results are compared with the analytically calculated values. Finite element analysis has been carried out using maximum stress criteria and the area of potential failure is found. The main objective of this paper is to find balance in results between "design by rule" and "design by analysis". Design by rule provides rules on how to design a steel reel shaft using analytical equations and other strict rules from design elements. Design by analysis provides rules on using numerical analysis, typically finite element analysis to design a steel reel shaft. The steel reel shaft has been geometrically modelled using SolidWorks. To check all stresses, linear static analysis is done using DSS Simulation and Ansys.
