Abstract

"TERMO-COMPENSAçãO INTEGRAL PARA ATUADOR ELETRO-MECáNICO". Trata-se de um método para compensar diferenças na taxa de termo-expansão em um ou mais elementos de um atuador eletro-mecânico. O atuador eletro-mecânico pode incluir um ou mais elementos, tal como um atuador piezelétrico com multicamadas de cerâmica (CMA) e um mecanismo para amplificar o deslocamento do CMA. Uma diferença na taxa de termo-expansão ou coeficiente de termo-expansão, CTE, entre os materiais no CMA e o mecanismo de amplificação pode levar os dois componentes a variar o tamanho em taxas diferentes conforme a temperatura ambiente varia. Uma vez que o mecanismo de amplificação proporciona amplificação substancial do deslocamento do CMA, a variação relativa, no tamanho dos componentes, devido ao fato de que a temperatura pode ser traduzida pelo mecanismo de amplificação como deslocamento do CMA. Isto pode resultar no deslocamento substancial do mecanismo de amplificação. Repor um elemento mecânico no mecanismo de amplificação com um elemento que possui um valor diferente para o CTE diminui substancialmente a diferença no CTE dos materiais, deste modo reduzindo o deslocamento induzido termicamente do mecanismo de amplificação. Adicionalmente, o material usado e o meio para interconectar o elemento de reposição no dispositivo de amplificação para termo-compensação pode manter alta rigidez da estrutura de sustentação de CMA, uma vez que a estrutura de sustentação transmite o deslocamento e a força do CMA para o mecanismo de amplificação, assim como aplicar uma pré-carga compressiva ao CMA. Adicionalmente, um alto nivel de força de pré-carga compressiva pode ser usado como uma parte adicional do processo de desenho total para ajustar o grau de termo-compensação requerido .
