Abstract

The invention discloses an automatic interface method for vibration cloud simulation of an avionics product based on ANSYS scripting language. The method comprises the following steps: inputting a 3Dgeometric model local address, material parameters, fixed restraint position, a load PSD spectrum value, a direction and an analysis type in a local visual interface, ; uploading data to the cloud end, importing ANSYS work simulation software at the cloud end into the 3D geometric model; giving material parameters to a 3D geometric model, updating and meshing the 3D geometric model, then applyingmodal boundary conditions, then performing post-processing of modal analysis, selecting one of random vibration analysis, harmonic response analysis and transient analysis according to a user, then applying different loads, and correspondingly performing post-processing. The cloud platform is used for simulation, the simulation efficiency is improved, and aviation electronic product fault behaviorsimulation and reliability prediction are rapidly and accurately conducted.

Description

technical field [0001] The invention belongs to the technical field of stress simulation of aviation products, and in particular relates to an automatic interface method for vibration cloud simulation of aviation electronic products based on ANSYS script language. Background technique [0002] Avionics products are generally composed of various electronic systems with independent functions, such as flight control systems, navigation systems, etc. They are the brains that control the operation of aircraft, and their reliability has always been valued. The structure of avionics products is roughly composed of chassis, circuit boards, components on them, and connecting parts.
