Analysis of the design of the drive in rack system

- Feb 05, 2020-

The drive in rack is composed of upright frame, bracket, bracket beam, top beam, middle beam, top tie, back tie and so on. The drive in rack is suitable for a relatively small number of products and the overall storage mode. Forklift trucks can be driven into storage areas, so the warehouse utilization rate is high, and are mostly used in cold chain logistics, beverages, food, dairy products and other fields.

Drive in rack system has the typical characteristics of FILO. The mode of forklift operation is continuous "high lifting" mode.After lifting the goods, the center of gravity is higher, forklift trucks are liable to sway along with the unevenness of the aisle ground and collide with the racks. It will affect the stability and safety of the rack structure.Therefore, drivers have higher requirements for driving technology, and the turnover speed and efficiency of the goods are also affected to a certain extent.

The structure design of the drive in rack is the key factor to determine the quality of the racks. In addition, the material, production technology, production equipment, fixtures and powder coating, etc. will directly affect the quality and grade of the racks. The main structure of the rack is a multi-time statically indeterminate space steel structure. It is very complicated to calculate its strength, stiffness and stability by the traditional classical mechanics method or dynamic method. Simplified calculation model can be used to analyze and optimize the structure in combination with domestic and foreign standards and test data. At present, most of the finite element structural strength analysis and stability analysis are used for auxiliary design and full-scale load test verification.

In the design process of the drivein rack, first of all, the standardization of the pallet unit should be carried out to determine the size, stack height and rated load capacity of the pallet. Then the overall structure of the drivein rack and the key dimensions of the storage unit, such as span, depth, storage spacing and height, can be planned to carry out the structure and components of the rack. In design, the key parameters should be verified by design or test, the simplified mechanical model should be established according to the case structure, and the strength, stiffness and stability should be set up according to the actual force (including seismic load) and load distribution of the rack, and the geometric parameters and mass characteristics of the corresponding components. Checking and checking, if necessary, can be verified through experiments to ensure that the design results are in line with the actual situation.
