Application of the Combined Vibration Analysis Method of the Overhead Traveling Crane to Prevent Negative Impact on the Structure and Personnel

Abstract

The subject of the study is the application of the combined method of vibration analysis for the study of dynamic phenomena in the elements of the overhead traveling crane structure that affect both the durability and reliability of structural elements and the health and efficiency of maintenance personnel. Research methodology - simulation of cargo lifting dynamics using Matlab Simulink and SolidWorks software, using combined calculations in which the system response generated from the solved system of differential equations in Matlab Simulink was used to excite the crane support structure during the FEM simulation in SolidWorks. The goal is to identify the vulnerabilities in the construction of overhead traveling cranes, by examining the dynamic phenomena in the structure and the effect of vibration on the safety of the crane's operation, on health, and the capacity of the operating personnel. Conclusion of the study. The proposed method allows more accurately and less costly to predict the response of the crane structure to various dynamic effects, particularly lifting and lowering the load. The presented models of FEM and rigid masses can become the basis for studies based on an integrated approach that integrates the dynamic model with the CE model. The influence of the action of various vibration frequencies on the machinist's body of the overhead traveling crane is analyzed.
