Transport systems of vertical storage find their application as flexible automated systems of storage and supply of storage objects with effective use of the available storage facilities due to their compact design.
The work solves the problem of ensuring the horizontal position of the cargo shelves during their movement and calculating the parameters and selecting the drive elements of such systems during their design.
We proposed analytical-numerical method for determining the coordinates of the center of attachment of the shelf and those of the guide roller of the mechanism for its horizontal stabilization. Computer programs have been developed to determine the trajectories of the centre of the shelf attachment and the trajectory of the guide roller relative to the center of the upper star of the chain drive. The programs provide the possibility of visual step-by-step visualization of the movement of the shelf relative to the center of the upper star, which makes it possible to evaluate certain limitations of the geometric parameters of the structure during its design. The kinematic parameters (velocities and acceleration) of the attachment points of the shelves on the curvilinear sections of their trajectories are determined. This makes it possible to evaluate additional inertial loads of structural elements. The adequacy of the obtained kinematic parameters is substantiated by comparing them with individual results obtained by graphic and analytical methods.
The results of the calculation and selection of drive parameters as well as elements of a specific vertical storage system and the design variant of the most loaded support node of the upper star of the chain drive are given.
