Research Of Anti-seismic Design Of A Aerospace Engineering

The seismic design of the steel tower container equipment in a aerospace engineering isthe most important task in the design project and the device earthquake-resistant calculationanalysis is an important part of the design process. Because it is not only relate to the modelselection in the required calculation and analysis of the engineering anti-seismic design,butalso to the safe operation of the equipments in the future directly, so which of the standards ormethods to be applied for design is the important question to be considered in the designprocess.In this paper, different seismic design and calculation analysis method of the steel towercontainer equipment in China and Russia is introduced respectively. Then through the actualseismic design of a aerospace chemical engineering steel tower container equipment, thecomparative studies of the two kinds of different analysis method is conducted in thestructural seismic calculation and analysis and the difference of the calculation results isanalysed. Its purpose is to provide the reliable data material for the structure seismic design ofthe aerospace steel tower container equipments and satisfying maximum realization ofobjetives of the reliability in the design. In the other, it could to provide guarantee for thesafety application of the equipments and another choice of structural seismic checking methodfor our steel tower container equipment designersThe following conclusions can be gain through the contrast analysis:(1) Through the design of the engineering examples, the two calculation analysismethods can meet the computing requirements of seismic design in the aerospace engineeringsteel tower container equipments entirely, and can ensure the safety and reliability of the useof equipment in the future.(2) In earthquake-resistant calculations, the vibration period computational expressionsof steel tower group are given in the calculation method of Russia, the relative displacementsof the gravity center for each tower structure are considered in the computational expressionsof the basic structure mode, but these were not taken into account in the calculation methodsand regulations of China.(3) Through the design calculation, these conclutions can be got that the calculation results are very approximate although the two methods exist some difference in calculatingways and steps. The choice of category of the land surface roughness and the wind vibrationcoefficient are not need to be considered in calculations of the wind loads in the methods ofRussia which compared to the methods of China. In the earthquake force calculations, theearthquake grouping, soil category and earthquake acceleration are also not need to beconsidered in the methods of Russia and the vertical earthquake force don’t have to beconsidered in the structural design of the structure, so the computing speed should be quicker.
