Split type structure of electronic controller and strength simulation method thereof

Abstract

The invention discloses a split type structure of an electronic controller and a strength simulation method thereof. The structure comprises a vertical plate; connecting pieces are integrally formed at the top and the bottom of the vertical plate along the front-back direction, a mounting plate is arranged on one side, far away from the vertical plate, of each connecting piece, and buckles are embedded on the front side and the back side of one side, close to each other, of the mounting plate along the left-right direction; a clamping groove is connected to the buckle in a clamped mode, and a protection plate used in cooperation with the vertical plate is arranged on the surface of the clamping groove. By designing the three split type buckle structures, the material cost is reduced while the structural strength is guaranteed, the process assembly efficiency is improved, and the buckle structures are divided in a solid grid mode; meanwhile, mapping refining cutting is carried out on the contact surface and the target surface, one-to-one correspondence of the contact surface and the target surface node position and number is achieved; finally, freedom degree coupling in the corresponding direction is carried out on the contact nodes and the target nodes based on the actual boundary, and the actual boundary connection form is truly simulated.

Description

technical field [0001] The invention relates to the technical field of numerical analysis, in particular to a split structure of an electronic controller and a strength simulation method thereof. Background technique [0002] The electronic controller module is a commonly used electronic device. It is mostly installed in the environment of the cabinet or sub-box. There are many uncertain vibration and impact loads in this environment. Under the action of the load, the electronic controller module will appear certain Reliability risks. In order to improve the anti-vibration performance of the overall structure, aluminum alloy metal materials are basically used at present, and the shell structure is fastened by bolt connection. [0003] However, the fastening method through the bolt connection has excessive strength redundancy. At the same time, for the simulation method of the buckle connection strength, the connection method of automatic binding of the contact surface is mos...
