  Desenvolvimento de Metodologia para Avaliação de Ganho em Ensaios de PIO (Pilot Induced Oscillation), Descrição: Este projeto de pesquisa desenvolve uma metodologia para avaliação de granho em ensaios de verificação de PIO (Pilot Induced Oscillation). As tarefas de manobra sintéticas (synthetic tracking task) são utilizadas para a demonstração. A teoria é baseada no conceito de entropia estatistica proveniente da teoria da informação e no modelo estrutural do piloto humano. O método é testado para manobras executadas no eixo lateral e oferece uma medida do ganho humano utilizado durante a sua execução em malha fechada. Para a modelagem da planta são empregados conceitos da dinâmica clássica. Dados de ensaios em vôo provenientes de uma aeronave de transporte certificada FAR-25 são utilizados para medir a razão entre o tempo gasto pelo piloto humano em uma malha fechada em posição versus o tempo em uma malha derivada da posição (roll vs roll rate). Esta medida é proposta como validadora da execução correta do ensaio. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Paulo Sergio Varoto - Coordenador / Andre Celere - Integrante., Financiador(es): EMBRAER - Cooperação., Número de produções C, T & A: 1

  Análise Dinâmica de Uma Viga Cantilever Excitada por Uma Fonte Não Ideal, Descrição: Este projeto de pesquisa tem como objetivo principal estudar as interações entre excitadores de vibração e a estrutura sob estudo. Em particular busca-se entender os mecanismos que induzem às chamadas interações não lineares entre uma dada fonte de vibração e a estrutura flexível a ela conectada. No presente projeto, um motor desbalanceado é montado na extremidade livre de uma viga metálica do tipo cantilever (engastada-livre). Um modelo analítico completo é derivado para o sistema motor-viga no qual as características da fonte de vibração são afetadas pelo comportamento dinâmico da viga, dando origem à interações não lineares, e, possivelmente a ocorrência de caos no sistema acoplado. Serão conduzidas simulações numéricas com o modelo analítico usando-se técnicas de perturbação na solução da equação do modelo, bem como serão realizados ensaios experimentais detalhados de um sistema com o objetivo de se validar o modelo matemático do sistema.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Doutorado: (1) . , Integrantes: Paulo Sergio Varoto - Coordenador / Vinícius Andrade - Integrante., Financiador(es): Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Bolsa., Número de produções C, T & A: 1

  Identificação de Grandezas Angulares em Dinâmica Estrutural Utilizando Materiais Piezelétricos, Descrição: Este projeto de pesquisa tem como objetivo principal o desenvolvimento de uma metodologia para a estimativa de funções de resposta em freqüência angulares (FRFAs) em dinâmica estrutural. Esta técnica utiliza transdutores piezoelétricos (PZT) do tipo bimorph para a medição da curvatura local da estrutura através do potencial elétrico induzido pela extensão e compressão do sensor. A partir da estimativa da curvatura, a rotação pode ser obtida diretamente através de várias técnicas de interpolação (polinomial, formas modais, etc.). É feita a modelagem teórica de estruturas uni-dimensionais do tipo viga e, estruturas bi-dimensionais do tipo placa, ambas istotrópicas onde se incorpora o sensor pizelétrico no modelo dinâmico correspondente. Modelos em elementos finitos são propostos no intuito de se avaliar a utilização destes sensores (bimorphs) aplicados à estimativa das FRFAs. Apresentam-se também resultados numéricos e experimentais considerando-se uma viga engastada-livre (cantilever) e resultados numéricos considerando-se uma placa simplesmente apoiada. Um procedimento utilizando algoritmos genéticos foi ainda desenvolvido no intuito de determinar a posição e dimensão ótimas dos bimorphs em estruturas do tipo viga.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Mestrado acadêmico: (0) / Doutorado: (1) . , Integrantes: Paulo Sergio Varoto - Coordenador / Thiago Rodrigo Cicogna - Integrante / Marcelo Areias Trindade - Integrante., Financiador(es): Fundação de Amparo à Pesquisa do Estado de São Paulo - Bolsa.
