Problems solved by technology
[0005] The technical problem to be solved by the present invention is: due to the insufficient bearing capacity of the impact testing machine, the whole machine test cannot be carried out. The purpose is to provide a fuel assembly impact test support device, which is specially designed for the fuel assembly impact test and can be used for the fuel assembly. The extension test provides the same power equivalent transmission as the actual installation state, and it is convenient to arrange sensors such as acceleration and strain in the test, so as to better ensure the completion effect of the impact test

Embodiment 1
[0030] A fuel assembly impact test support device, comprising a flange 3 with an opening, a mounting base plate 4, a column 2 arranged between the flange 3 and the mounting base plate 4, and a spring plate installed on the flange 3 and at the position of the opening component 1;
[0031] The number of the columns 2 is multiple, set around the flange 3, and the plurality of columns 2 are arranged in parallel, the tops of the columns 2 are connected with the flange 3, and the bottom ends of the columns 2 are fixed with the installation base plate 4;
[0032] A limit assembly 5 is also arranged on the column 2, and a spider plant simulation body 6 located between the flange 3 and the installation base plate 4 is arranged on the limit assembly 5;
[0033] The spider plant simulation body 6 is provided with a threaded hole 7 .
[0034] According to the design requirements of the support device for the extension test in the impact test standard, and considering the installation wei...
Embodiment 2
[0041] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the specific structure, and the settings are as follows:
[0042] The limiting assembly 5 includes two first limiting rods parallel to each other, a second limiting rod that is arranged between the two first limiting rods and cooperates with the first limiting rods to limit the position of the spider plant simulation body 6; The first limiting rod is fixed on the column 2 through a connecting rod.
[0043]The flange 3 described in this embodiment is a return-type flange, and the number of columns 2 is four, which are respectively connected at the four corners of the return-type flange, such as figure 1 and figure 2 shown.
[0044] In this embodiment, a threaded hole 7 is also provided on the limiting assembly 5, and the threaded hole 7 on the limiting assembly 5 can effectively adjust the gap between the fuel assembly and the limiting assembly 5, better simulating actua...

Abstract
The invention discloses a support device for a fuel component impact test and a frequency adjustment method thereof, which solves the problem in the prior art that the impact test machine cannot carry out a complete machine test due to insufficient bearing capacity. The invention includes a flange with an opening, a mounting base plate, a column arranged between the flange and the mounting base plate, and a spring plate assembly installed on the flange and located at the opening position; the number of the columns is multiple, surrounding the flange It is arranged in a circle, and a plurality of uprights are arranged in parallel, the tops of the uprights are connected with the flanges, and the bottoms of the uprights are fixed with the installation base plate; the uprights are also provided with a limit assembly, and the limit assembly is provided with a The spider plant simulation body between the blue and the installation base plate; the spider plant simulation body is provided with threaded holes. The invention can provide the same power equivalent transmission as the actual installation state for the sub-machine test of the fuel assembly, facilitates the arrangement of sensors such as acceleration and strain in the test, and better guarantees the completion effect of the impact test.
Description
technical field [0001] The invention relates to the field of test simulators, in particular to a fuel assembly impact test support device and a frequency adjustment method thereof. Background technique [0002] Fuel assembly is one of the key equipment of nuclear power reactor. During the operation of the whole life cycle, the fuel assembly will inevitably bear the impact load, and the impact load will directly affect the reliability of the fuel assembly, and finally affect the tactical performance and safety of the driven ship. Component impact testing. [0003] In order to determine whether the design of fuel assemblies for nuclear power plants of new test reactors can meet the overall specified life-cycle requirements, it is necessary to carry out impact tests on fuel assemblies to ensure that their impact resistance meets the requirements of relevant specifications and provide a test basis for their engineering applications. [0004] Due to the limitation of the functi...
