Abstract: In the practical application of aerial work platform, the boom system is frequently subjected to various vibrations and impacts, which seriously affects the stability of the construction process and even endangering the personal safety of the construction personnel. The paper focuses on the boom system of aerial work platform, aiming to provide theoretical basis for its design, optimization, and control. Taking the DGS25Y telescopic boom aerial work platform as the research object, when its boom system is in the state of micro vibration and low damping, the paper uses the simplified half model of theoretical analysis and the method of combining with MATLAB simulation research to explore the influence of boom stiffness on the boom vibration amplitude of aerial work platform, reveals the law affecting the boom head vibration, and provides a theoretical basis for the design and optimization of aerial work platform.

Key words: aerial work platform; boom system; dynamic analysis; motion control
