Server sinking deformation prevention method and system based on finite element analysis

Abstract

The invention discloses a server sinking deformation prevention method and system based on finite element analysis. The method comprises the steps of building virtual modeling on a server case and a server assembly through simulation software; performing grid division and material attribute setting on the case through finite element analysis software; applying fixed constraint to the two side walls of the case, and applying a vertical load to the bottom plate to obtain the sinking deformation distribution condition of the bottom plate; installing the initial number of micro-reinforcement models additionally at all positions, corresponding to all the areas with the sinking deformation exceeding the preset threshold value, on the surface of the bottom plate; rechecking the sinking deformation distribution condition of the bottom plate, and adjusting the number of the micro-reinforcement models according to the sinking deformation distribution condition until the sinking deformation quantity is within a preset threshold value; in the production stage, setting micro-reinforcement modules with the same number as the micro-reinforcement models additionally at the corresponding positions of the surface of the bottom plate. The server can be prevented from generating overlarge sinking deformation in the using process, meanwhile, later repair adjustment is avoided, the research and development production cycle is shortened, and the research and development production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a method for preventing sinking and deformation of servers based on finite element analysis. The invention also relates to a server anti-sinking deformation system based on finite element analysis. Background technique [0002] Under the action of the server system's own load (self-weight), the bottom structure of the server case will sink and deform, causing the bottom plate of the server case to produce concave uneven deformation. When designing a server system, the server chassis should have sufficient structural strength to avoid excessive sinking deformation, affecting the operation of server components and the disassembly and maintenance of adjacent servers in the cabinet. [0003] Currently, servers are generally installed vertically in a cabinet, and multiple servers are stacked and distributed. The sinking deformation of the server chassis will not only affect the defo...

Problems solved by technology

[0005] However, the method of reinforcing the bottom plate of the chassis and reducing the sinkage by pressing the line plate will not only damage the structure of the server chassis itself, but also affect the structural strength of the chassis bottom plate when the number of line pressure plates is too large, resulting in an increase in the height of the chassis , takes up more installation space, and, because the actual effect is not clear when pressing the line board, it can only be arranged based on experience, resulting in the chassis bottom plate needing to repeatedly adjust the parameters such as the number and position of the pressing line board, resulting in research and development.
