Description

technical field [0001] The invention relates to the field of computer simulation verification of equipment hoisting, in particular to a method and device for simulating the hoisting process of large equipment. Background technique [0002] With the development of equipment hoisting computer simulation verification technology, many large-scale and high-value equipment are needed in industrial production. Due to the difficulty in hoisting these large-scale equipment, once any damage occurs during the hoisting process, it will bring significant losses to industrial production. Therefore, In order to ensure the smooth progress of the large-scale equipment hoisting process, the large-scale equipment hoisting process can be simulated before the large-scale equipment hoisting. [0003] In the prior art, when simulating the hoisting process of large-scale equipment, the hoisting scheme is first drawn up, and the components required in the hoisting process are determined according to...
