A Modal Analysis of Forced Vibration of a Piezoelectric Plate with Initial Stress by the Finite-Element Simulation

Analysis and optimization of pre-stressed modal features of ship anchor support parts

“…Establish a static structural analysis module in ANSYS Workbench and couple the modal analysis module with the structural analysis module. The preprocessing stage of the model includes defining material properties, meshing, applying boundary conditions and loads, and setting modal calculation conditions [11,12]. Define the material attribute of the model as Q235 in the material library, set the quality parameter as the optimization objective, and code it as P7.…”

Modal and vibration response characteristics of rotating support platform

“…As an important equipment in the production and transportation of different industries, the rotating support platform can smoothly transmit the speed and torque output by the motor to the supported equipment, completing oscillation, mixing and other tasks. During the process, it is subjected to significant dynamic loads, which have a huge impact on its working stability [1]. Taking the rotating support platform of a concrete mixer truck as an example, during transportation, the planetary gear reducer needs to adjust the concrete mixing drum to maintain continuous rotation and mixing, to avoid concrete compaction or segregation due to insufficient mixing during transportation, which may affect the use of the construction site [2].…”

Modal analysis and vibration response test of tank body

“…In addition, it can also serve as the basis for other dynamic characteristics analysis, providing a basis for the structural dynamic characteristics, vibration characteristics and vibration fault diagnosis of structural systems, so as to optimize the design. In addition to considering the strength, vibration failure is usually also used as the main failure mode of the tank body of the semi-trailer for cryogenic liquid transportation in actual operation [5,6]. In the process of product inspection, vibration tests are carried out to simulate the vibration response of the tank body of the semi-trailer for cryogenic liquid transportation under the driving conditions.…”
