Description
Technical field
The present invention relates to finite element analysis technology, be specifically related to a kind of large-scale tank suspension type static test device.
Technical background
Along with continuous progress and the development of Models For Space Science And Technology, large-scale and even the heavy launcher of each scientific and technological power development is an inexorable trend of world's rocket development, low temp fuel is the propelling energy of contemporary advanced space vehicle, these fuel are contained in the tank of supercharging, and tank is in production, storage, lifting, park, transport and flight course will bear axial compression, moment of flexure, shearing, the load such as interior pressure and temperature, so tank structural strength in use, rigidity and low temperature combination property are to design and manufacture extremely important, need the checking by low temperature slow test.
At present, carrier rocket of new generation large-scale tank low temperature slow test method is applicable to the tank low temperature slow test method of routine.Usually carrying out in low temperature slow test examination Rocket tank, the force transferring structure of the load such as the axial compression that tank bears, moment of flexure, shearing is boundary condition simulation part, and non-genuine power transmission border structure part; The applying that test requirement lower end, border is clamped, upper end realizes the load such as axial compression, moment of flexure, shearing by general static loading equipment; Interior pressure realizes the applying of inner pressuring load by spirit pillow supercharging before tank, and the bearing frame building gantry frame type can meet test loading demand.
For bundling low temperature associating slow test project before core level, except the applying of inner pressuring load is substantially identical with Normal practice, but technology and the experience of just low temperature slow test in the past can not be indiscriminately imitated completely, more not having can the external similar experimental technique of reference and method, therefore must according to the structure of the Long March No. five rockets self, load, the feature such as environment and border, and the actual conditions such as field condition and auxiliary facility are implemented in the test of large delivery test site, Tianjin, strictly carry out many-side to consider, and around the accuracy that test load applies, experimental scale, difficulty is implemented in test, test period, test funds etc., design studies goes out a set ofly to meet this Project R&D stage, the large-scale tank suspension type low temperature slow test method that in low temperature slow test project, difficulty is maximum.
Testpieces installation situation before core level required by binding low temperature associating slow test task is shown in Fig. 1, multi-section section associating assembly in low temperature Combined Trials, bundlees brevicone 2 before brevicone 4 after bearing 5, one-level oxygen case, one-level oxygen case 3, one-level oxygen case before brevicone 7, one-level inter-tank section 6,4 before comprising one-level hydrogen case.Apply connected load and comprise the rear end face sectional axis compressive load of brevicone 7 and the inner pressuring load of one-level oxygen case 3 before centre-point load on 4 binding bearings 5, one-level hydrogen case.Before test border requires, the upper surface on transition rings border 1 is connected with test built-in boundary 8.Structure of participating in the experiment required by this project is multi-section section associating assembly, and test setting height(from bottom) also can increase a lot naturally thereupon; In order to make one-level oxygen case 3 be in low temperature environment near the regional area of front binding 4, then testpieces just must put installation, and test requirement upper end, border is clamped simultaneously; The comparatively near and single-point load of binding bearing 5 concentrated force load applying point distance test (DT) part reaches 300 tons; Add the sectional axis compressive load of brevicone 7 before one-level hydrogen case, the axial load that test installation frame need balance is more than 1240 tons; Consider the degree of difficulty of the field conditions such as the test platform size of test site limits, ground hard point tonnage is little simultaneously, all bring huge challenge to plan design and test implementation process.
Summary of the invention
Goal of the invention
