Embodiment Construction

[0049] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] Please see figure 1 , the first embodiment of the metal shrapnel simulation method of the present invention is used for metal shrapnel simulation of mobile terminals, and the metal shrapnel simulation method includes the following steps:

[0051] Step S100, receiving the model data imported by the user, the model data including the shape of the metal dome, the material of the metal dome, the pressed vertex of the metal dome and the fixed bottom surface of the metal dome. The materials used to make metal shrapnel are often used, and custom materials can be stored, so that users can directly call the custom material properties.

[0052] Step S200, setting a rigid pressure block whose assembly relationship is contact for the pressurized vertex; where the assembly relationship of contact means that the two can mov...

Abstract

The invention discloses a metal shrapnel simulation method and device. The metal shrapnel simulation method comprises the steps that model data imported by a user is received, wherein the model data comprises the shape, material, pressed vertex and fixed bottom surface of a metal shrapnel; the pressed vertex is provided with a rigid pressing block which makes contact with the pressed vertex in assembly relationship; the metal shrapnel is subjected to mesh generation for finite element computation; the constraint relation of the fixed bottom surface is set to be fixed; first displacement, towards the fixed bottom surface, of the rigid pressing block is set, and second displacement to the original position is set; during simulation of the first displacement and the second displacement of the rigid pressing block, the state change process of the metal shrapnel is obtained through finite element computation. The metal shrapnel simulation method and device have the advantage of improving the efficiency in simulating the actual usage scenario of the metal shrapnel.

Description

technical field [0001] The invention relates to the field of simulation, in particular to a metal shrapnel simulation method and device. Background technique [0002] Mobile terminals need to be assembled with as many components as possible within a certain space. Therefore, the mobile terminal has a compact structure and limited internal space. Usually the antenna feed point, the grounding of metal parts, and the I / O transmission connection are connected by metal shrapnel. However, once the shrapnel fails, it will affect the function of the whole machine. Therefore, metal domes used in mobile terminals must be durable and stable. [0003] However, in the process of verifying and optimizing the metal shrapnel, the simulation effect is poor and the efficiency is low, and the actual use scenario of the metal shrapnel cannot be simulated efficiently. Contents of the invention [0004] The main purpose of the present invention is to provide a metal shrapnel simulation meth...
