The article offers a point of view on the study of vibration load of synchronous threaded connections from the analysis of vibration recording in relative units. There are six main steps that can be used to "read" the vibration of the threaded connection of agricultural machinery.
Based on the vibration analysis, the concept of vibration load analysis of synchronous threaded connections of agricultural machinery is proposed. threaded connection of agricultural machinery allows to judge the load of the threaded connection by transverse forced vibration according to the following parameters: the number of frequencies relative to the X and Y axes; the range of displacements along the X and Y axes; the ratio of the sides of the vibration rectangle; presence and placement of dominant vibration units; closed or not closed trajectory, whether there is an axis of symmetry; the direction of growth of the set of points with time on the trajectory.
Studies are relevant for use in simulation modeling of this process in order to predict the development of the threaded connection and planning preventive actions.
