Vibrating Plate Design: Exploring Dynamic Requirements

Abstract

This study encompasses the design and dynamic analysis of a previously used compact, portable vibrating plate machine. Utilizing Siemens NX 2021 for the precise modeling of the machine's components, the design prioritized simplicity and functionality, resulting in a 450 mm x 450 mm aluminum alloy structure, suitable for a wide range of research applications. A detailed modal analysis, conducted to ascertain the system's natural frequencies, revealed six predominant modes, ensuring operational frequencies of 110 Hz to 130 Hz were strategically avoided to mitigate resonance risks. Complementing this, harmonic response analysis evaluated the system's behavior under an applied cyclic load, confirming the suitability of the chosen actuator, model VL181206-160H, which provides optimal vibrational force without overstressing the machine. The findings affirm the machine's capability to perform efficiently within the target frequency range, with the design and selected actuator offering a robust solution for consistent and safe vibrational analysis, essential for field and laboratory applications.
