The dynamic effects and impacts in electronics

Modal Analysis of Airborne Equipment Mounting Rack

“…Mathematical model of Modal analysis, Dynamic characteristics of a N degrees freedom linear system can be described by N order matrix linear time-invariant differential equation [3].…”

“…Moreover, the vibration experiment is supposed to start after the equipment being manufactured and formed. So some part of the equipment is tested again and again, leading to long production cycle, low rate of finished products and high cost of production [3]. Dynamic characteristics of structure obtained by the method of finite element numerical calculation can put forward structure optimization scheme pertinently, reduce design cost and short production cycle on the condition of meeting high reliability and lightweight of the airborne electronic equipment [4][5][6].…”

Optimal Control of Temperature Modes of the Instrumental Constructions of Autonomous Objects

“…When the heat generating device is located on the surface of the construction, the standardizing function allows to reduce the initial inhomogeneous boundary problem to the standard form of (1) -(3) that can be written as follows with the help of application of the Green's function [2,3]: Let us consider the possible ways of development of an automatic stabilization system. The dependence of thermal deformation of the structure on the temperature can be described by the known linear relations [5]. This fact does not allow using a quadratic deviation,…”
