Designing And Heat-Structure Coupled Analysis Of The Installed Components Of The Space Exploration Equipment

The installed components of the space exploration equipment, which are important components of detector will have a direct impact on the measuring precision and the static and dynamic characteristics. Except that, an important design principle is doing everything possible to reduce the weight of equipment to meet the requirements of carrying and launching. In this paper, designing different installed components according to the working characteristics of the magnetometer and EUVE and doing heat-structure coupled analysis to meet the measuring precision and mechanical strength with the lightest weight.This article basing the principle of the working and lightest weight designs the magnetometer floor, the EUVE cover and tube, chooses the suitable materials and completes the structural design of the installed components.In order to get the stress and deformation characteristics when the magnetometer and EUVE are launched and under the extreme conditions, determining all kinds of physics, the initial and boundary conditions and establishing the models of magnetometer floor, EUVE cover and tube which are done the heat-structure coupled analysis and static analysis. Through it, we do not only get the stress and deformation distribution, but also identify the high-stress, high-displacement region, which will provide reliable basis for the installed components design.In this paper, doing the stress analysis to the EUVE tube which has different thickness and fillet size, calculating the tube strain which will influence the sensor accuracy, and determining the best size of the EUVE tube structure.
