Abstract

The invention discloses a dry-type transformer mechanical vibration simulation analysis method under a highway transportation working condition, and the method comprises the steps: employing finite element simulation software HyperWorks to simulate the structural size, assembly relation and fixing form of a transformer to the maximum degree, guaranteeing the grid quality, and improving the solvingefficiency; starting from the perspective of probability statistics; selecting a corresponding road transportation machinery environment condition to simulate road surface bumping borne by the carrying vehicle; random vibration simulation of the transformer is completed; obtaining a stress response probability statistical value through simulation; comparing the mechanical strength attributes of the material; according to the method, the structure where the mechanical strength of the transformer is most likely to fail in the highway transportation process is judged, the problem that the randomness of road bump cannot be simulated through transient impact simulation is solved, the reliability of the transformer under the highway transportation working condition can be evaluated in advance in the product research and development stage, and the most reliable product structure is optimized.

Description

technical field [0001] The invention relates to the technical field of transformer transportation, in particular to a mechanical vibration simulation analysis method of a dry-type transformer under road transportation conditions. Background technique [0002] Dry-type transformer is widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformer refers to a transformer whose iron core and winding are not immersed in insulating oil. Dry-type transformers are generally assembled in the factory and transported to the destination by kilometers. However, the structural integrity of dry-type transformers will directly affect the actual work and operation. Avoiding mechanical strength failure of the structure is an important issue in the design of transformer transportation schemes. After long-distance transportation by road, the dry-type transformer structure will be damaged by vibration. [0003] How...
