Selland, Carlos Lange","doi":"10.32393/csme.2021.180","DOIUrl":"https://doi.org/10.32393/csme.2021.180","url":null,"abstract":"A transient thermal circuit model was developed by the AlbertaSat Student Team for the Northern SPIRIT cube satellites: Ex-Alta 2 (3U), YukonSat (2U) and AuroraSat (2U), which are to be launched into Low Earth Orbit. The model was used to study heat transfer and determine temperature profiles over time in each CubeSat. The thermal resistance analogy for conductive heat transfer was utilized, assuming convection as negligible under vacuum conditions. The thermal circuit model was used because of its greater modularity and computational efficiency, when compared to finite element analysis simulations, particularly for preliminary analysis when internal stack configuration is subject to change. The approach has also shown adaptability and modularity between different sizes of CubeSat structures. Thermal circuits were created for each face of the satellite, which allows for varying inputs to each side based on thermal loading. The simulations will aid in determining whether modifications to the CubeSats need to be made to ensure all on-board components remain within their predefined thermal operating ranges during orbit. The transient thermal models for the Northern SPIRIT constellation are simulated with LTSpice XVII, a circuit simulator written by Linear Technologies Inc. The thermal circuit simulations use electrical properties to represent thermal properties; where current sources represent heat sources, electrical resistances represent thermal resistances, capacitors represent heat capacity, and voltage differences represent temperature differences. LTSpice allows for accurate representation for all components within the satellites, as long as an association with thermal resistance or capacitance can be made. The thermal equivalent of each printed circuit board (PCB), the solar panels, the deployable components, and satellite bus for all three CubeSats has been created in LTSpice. The heat transfer on the outer surfaces and heat generation sources on PCBs have also been implemented to account for the transient nature of thermal loading during orbit. The individual CubeSat models will be validated through tests in the thermal vacuum","PeriodicalId":446767,"journal":{"name":"Progress in Canadian Mechanical Engineering.

The squirrel cage fan (SCF), also known as forward-curved multiblade centrifugal fan, is widely used in vacuum systems. Most of researches so far used commercial software to study and optimize the SCF. In the present study, a complete automatic optimization process loop is developed based only on open source libraries: Dakota, Salome and OpenFOAM. Up to seven design parameters are selected. The Latin Hypercube Sampling (LHS) method is preferred to determine the design points and then the Kriging and Efficient Global optimization (EGO) metamodels are built. A 3D incompressible simple FOAM solver is coupled to the Multiple reference frame (MRF) approach to model the flow in the SCF. An efficiency improvement of 8.46% is reached by the EGO approach. A strong vortex is observed in the cutoff region. The optimal design is finally validated against the produced prototype, with an error of 3.4% on the efficiency.","PeriodicalId":446767,"journal":{"name":"Progress in Canadian Mechanical Engineering.

Czekanski","doi":"10.32393/csme.2021.224","DOIUrl":"https://doi.org/10.32393/csme.2021.224","url":null,"abstract":"—Additive manufacturing is a crucial new trend that is steadily taking over traditional methods. Despite its many advantages, the anisotropic nature of the produced parts of most additive manufacturing methods is a significant disadvantage. Of the methods that suffers from this anisotropy drawback is the fused filament fabrication (also known as fused deposition modeling). As a result of this anisotropy in the mechanical properties, a need arises to define the optimum direction of printing to be used for a certain loading condition. Topology optimization is a great numerical design tool for weight and material savings. It’s basically used to determine where to put material to optimize a certain objective function under specific constraints. The design variables in a topology optimization are typically chosen as the densities of the finite elements. Adding the printing direction as an additional design variable complicates the problem further. This eventually gives rise to a huge selection of local minima and further increases in the computational costs. In this work, we attempt to utilize artificial neural networks to tackle this problem. Selected results of mass minimization problems run in ANSYS are used as input data for the neural network model, which is used to predict the fiber angle that has the minimum mass under specific stress constraints. Results so far are promising with small errors considering the computational savings achieved.","PeriodicalId":446767,"journal":{"name":"Progress in Canadian Mechanical Engineering.
