“…In the case of PCB boards and integrated circuits, their reliability depends, among other factors, on the possibility to endure vibration loads and impacts that can affect their performance. Modal analysis can thus be a very useful tool for engineers to reveal vulnerable areas and avoid premature failure [6][7][8].…”

Printed circuit boards constitute the basis of most electronic devices and are mainly fabricated of thin copper films bounded to fiber epoxy laminates, such as FR4. Vibrational stress can induce device failure, and hence, studies addressing their modal properties have important applications. In this paper, cantilever samples made of bare copper bounded to FR4 have been studied to analyze, for the first time, the vibration behavior of specimens with different aspect ratios, with and without central holes of different diameters. Natural frequencies and damping ratios were determined experimentally and analytically using a finite element method for four groups of samples with a very good correspondence between both methods. The fundamental resonance frequency of all the specimens was found to be less than 40 Hz and the influence of a central hole was not significant to affect the modal properties.

“…The optimized data are modeled and imported into ANSYS, and the computer simulation software ANSYS Wrokbench and Pro/E are interfaced and exchanged [22,23]. According to the simulation results shown in Figures 7 and 8, the first six modal values are within 68 Hz to 125 Hz, especially according to the first three modal values and cloud image analysis, which is far from resonance, which means very stable.…”

Aiming at the problems of low efficiency, heavy quality, and high cost of traditional components, it is necessary to study a design and analysis method of non-standard components. Taking the non-standard parts-turret loading and -unloading device as the carrier, the key parts of the non-standard parts are extracted for structural design and the multi-objective mathematical model and modal theory model are established. The optimization analysis of the key parts is carried out by genetic algorithm. Finally, the optimization results are compared and simulated by ANSYS Workbench. The results show that: in this case, the genetic algorithm optimized data with other data, the overall quality difference is 4.1%. The first six order modal values in the optimized results are in the range of 68 Hz to 130 Hz, which provides a basis for similar research in the future.

“…However, even with such a system, it is not easy to get rid of the vibration owing to the motion complexity in a diesel engine, although the development of electronics, sensors, and computer-aided measurement technology has led to improved vibration isolation systems in marine engineering. There have been many studies to find the vibration characteristics of diesel engines (1,(7)(8)(9)(10)(11)(12) and on how to reduce vibration with various vibration isolation systems. (13)(14)(15)(16) However, there has been little research on how to precisely locate vibration isolators.…”

Different centers of mass (CMs) of a diesel engine were set to find their effects on the vertical vibration of an engine. To understand the effects and reduce vibration during sensing, we changed the location of the CM of the engine and performed a simulation to obtain data such as the vertical movements, velocity, torque, and acceleration of the vertical springs of isolators. The data showed that a 0.1 mm higher CM than the original CM of the engine reduced the amplitude of the vertical vibration by 4.35% and the velocity of the vertical vibration by 45.7% at a fixed rotation speed of the engine of 1000 revolutions per minute (rpm). Different CMs did not significantly affect the torque and acceleration. Instead, the phase of the vertical movements, the velocity, and the acceleration significantly changed with the CM in the simulation. The results imply that the CM needs to be considered in the design of the vibration isolation system of a diesel engine to increase the accuracy and lifetime of sensors used in vehicles under severe vibration conditions.
