Thermal Design

Thermal design and analysis of a satellite instrument is introduced in this paper. Some methods were adopted to help heat conduct and a finite element model was built. The analysis results showed that the temperature scopes of the main structures are from 45°C to 65.8°C and all of junction temperatures of the components are lower than the derated maximum junction temperatures themselves and leave enough design margins, which match the requirements of thermal analysis.

ANSYS finite element model of bearing type steel arch bridge is established. The arch bridge column overall mechanics performance on fire is analyzed through thermal analysis module of the software. And the internal force and deformation of the different pillar of fire is calculated. The conclusions show that structure deformation of the fire and the fire near pillar in a certain range has certain increase. Displacement of the fire in the bridge column is change with the increase of the temperature. In the local pillar by fire ,arch rib alignment is not affected in local pillar.

Basic Equations

A finite element model and its equivalent electronic analogue circuit has been developed for fluid transients in hydraulic transmission lines with laminar frequency-dependent friction. Basic equations are approximated to be a set of ordinary differential equations that can be represented in state-space form. The accuracy of the model is demonstrated by comparison with the method of characteristics.

Molecular Organisation

The processing of polymers is highly complex. The study of their crystallisation assumes an important role and needs to be carefully detailed. Scattering experiments can be used to study polymer molecular organisation. However these procedures are still very multifaceted leading to the need for planning all the details in the experiments that are to be performed. This manuscript presents a finite element model developed to study the temperature variation of a T Jump System, which has been used for studying polymer behaviour with the NIMROD instrument at the ISIS Neutron and Muon Source, UK. Results show that the variation across the sample was 2oC at a maximum temperature of 70oC and 1oC at a maximum temperature of 50oC.
