Problems solved by technology

[0003] The skid needs to be used outdoors. In addition to its own gravity, it may also receive wind loads, snow loads, and earthquake loads. The calculation of the skid is more complicated and cumbersome. The calculation period is relatively long and the quality requirements of personnel are relatively high.

Abstract

The invention discloses a verification method of a skid-mounted chemical plant framework structure. The verification method of the skid-mounted chemical plant framework structure comprises the steps that (1) a tested skid-mounted framework model is obtained, a coordinate system is built according to the skid-mounted framework model, a horizontal plane is set as an XOY plane, and the direction of a vertical beam is the Z direction; (2) after the weight of all devices on the tested skid-mounted framework is obtained, the mass point of each device is simplified to the weight center, the mass points are loaded to a supporting surface by means of SOLIDWORKS software, and then the skid-mounted framework model is simplified into a finite element model; (3) static analysis is carried out on the skid-mounted framework model under different work conditions; (4) if the stress under different work conditions is within a permissible stress range and the maximum deflection of a cross beam does not exceed 1 / 300 of the length of the cross beam, the framework structure meets the design requirement. According to the verification method of the skid-mounted chemical plant framework structure, the work conditions which may occur in the use process of the skid-mounted structure can be calculated clearly, various work conditions are combined, and a precise result can be obtained.

Description

technical field [0001] The invention relates to skid-mounted equipment in a chemical plant, in particular to a checking method for a skid-mounted frame structure. Background technique [0002] With the improvement and upgrading of chemical plants, there is a trend of skid-mounting in the design of chemical plants. Skid-mounting is to integrate some equipment or valves on a frame structure similar to a container, so that the original workload on the chemical plant site will be reduced. It was transferred to the workshop, which greatly accelerated the construction process of the chemical plant, and the production of skids in the workshop also guaranteed the product quality. [0003] The skid needs to be used outdoors. In addition to the influence of its own gravity, it may also receive wind loads, snow loads, and earthquake loads. The calculation of the skid is more complicated and cumbersome, the calculation cycle is relatively long, and the quality requirements of personnel ...
