The authors applied the Finite Element Method (FEM) to analyze the electro-mechanical transformation and micro dynamical characteristics of a piezoelectric panel loudspeaker with triple layered piezoelectric ceramic slices in 2×2 rectangular arrangements. According to the simulated micro-vibration data, the authors built an acoustic analysis model combined with a linear superposition method to rapidly...
The traditional reliability evaluation method based on T&E (Test and Evaluation) easily results in less efficient and more costly R&D process. However, reliability evaluation with only the thermal loading or the vibration loading cannot accurately simulate the environment of the usage, which therefore does not provide insights on how to avoid defects in the designing process as well. Therefore,...
The paper demonstrates an analysis example of a flange-sealing structure. Taking the O-ring width and bolt pre-tightening force as tolerance-parameters, obtaining the stress response surface according to the loop analysis results by ANSYS, then extracting the stress results of randomized parameters from the stress response surface, plotting the stress response distribution and calculating the reliability...
