“…Instead, they utilize a series of physical principles and material characteristics. Passive tracking systems leverage the physical properties of materials, such as thermal expansion and contraction, typically using shape memory alloys or chlorofluorocarbons [10,11]. When the photovoltaic panels are not perpendicular to the Sun, uneven heating on both sides causes one side to expand and the other to contract, aligning the panels as vertically as possible with the Sun.…”

“…To further analyze the impact of passive and active control on ST technology, scholars have conducted in-depth research. Passive tracking systems rely on the physical properties of materials such as shape memory alloys or chlorofluorocarbons [10,11]. When photovoltaic panels are not oriented vertically toward the Sun, uneven heating on their sides causes expansion on one side and contraction on the other, aligning the panels as closely as possible with the Sun to achieve tracking objectives.…”

“…Neste campo, existem tanto aquecedores solares comerciais quanto aqueles que buscam uma solução de baixo custo, como os apresentados pelas pesquisas de Siqueira et al (2011) e Verraci et al (2008) Por se tratar de um equipamento de instalação geralmente fixa a inclinação das placas coletoras também é uma variável e tem influencia direta na eficiência do modelo, sendo esta, relacionada à localização geográfica da instalação, conforme simulação para otimização feita por Stanciu e Stanciu (2014). Contudo, pode haver necessidade de uma resposta ainda mais eficiente no aquecimento solar, neste caso, uma estrutura de rastreamento do movimento solar seria o ideal, o que foi pesquisado por Neagoe et al (2014).…”

RESUMO-O aumento na demanda social por energia apresenta-se à tona, principalmente, por fatores como a evolução tecnológica e o crescimento industrial e demográfico. As fontes tradicionais de energia, tais como o petróleo, o carvão e o gás produzem resíduos exauridos da combustão que são agentes poluidores e extremamente nocivos. Uma das opções energéticas sem resquícios residuais é a energia solar, que além de ser limpa, tem como vantagem o fato de ser renovável. Para obtê-la, faz-se necessário a conversão da radiação solar, o que pode ser feito de duas maneiras: a forma direta, quando há conversão de energia solar em energia elétrica ou a forma indireta, valendo-se das propriedades térmicas da radiação. Este trabalho tem como intuito o estudo de tecnologias de utilização térmica da energia solar utilizando-se, para isso, da análise de referenciais da área tanto para aquecedores solares no formato plano quanto para concentradores solares.

“…In this case, the guided body and the other bodies are connected by a number of kinematic chains imposing geometrical or kinematical constraints among these. As examples, these mechanisms are used in the field of manipulators-robots [1,2], guiding mechanisms for car wheels and axle [3], solar tracking systems (solar thermal, photovoltaic) [4,5] etc.…”

A large variety of methods are mentioned in literature for the structural analysis and conception of parallel linkages, applicable to planar and/or spatial mechanisms developed for various applications as manipulators-robots, guiding mechanisms for car wheels and axle, solar tracking systems. Modern design requires today a unitary description of all the mechanisms in a product (including linkages) for complex simulation and optimization on software platforms. This paper proposes a seven steps general method for the parallel linkages’ structural analysis and synthesis, considered as Multibody Systems. The method is based on the concept that describes a mechanism by a minimum number of bodies. Using as input data the application area, the motion space, the mechanism mobility and the type of joints, all possible fundamental multibody chains are obtained and, based on, the corresponding mechanisms. The method is described in detail and applied for the geometrical constraints of rotational (R), spherical (S), translational (T) and their combinations types. As example, a tracking system for a solar thermal platform, based on a parallel linkage with two degrees of freedom with R, S and T joints is presented.
