Abstract in Portuguese
Este trabalho apresenta o projeto e desenvolvimento de dois sistemas de calibração de acelerômetros. O primeiro sistema foi desenvolvido a partir de um sistema interferométrico laser Hewlett-Packard (HP 5529A), utilizado como padrão de referência absoluta. Este sistema foi projetado com o propósito de calibrar acelerômetros-padrão de comparação e acelerômetros-padrão de transferência. O segundo sistema de calibração utiliza como padrão de referência acelerômetros-padrão de comparação. Este segundo sistema foi projetado com o objetivo de calibrar acelerômetros de uso corriqueiro. Desta forma, o conjunto formado pelos dois sistemas de calibração podem ser rastreáveis até os padrões primários, nacionais e internacionais. Para cada um dos sistemas de calibração são apresentadas discussões relativas às suas características construtivas, aos testes de operação e às avaliações sobre os desempenhos alcançados.

Abstract in English
This work presents the design and development of two accelerometer calibration systems. The first system was developed from a Hewlett-Packard laser interferometric system (HP 5529A), taken as an absolute reference standard. This system was designed to allow calibration of comparison standard accelerometers and transfer standard accelerometers. The second calibration system, which employs comparison standard accelerometers as reference, was designed to calibrate common use accelerometers. Thus, the arrangement of the two calibration systems can be traceable until the primary national and international standards. For each calibration system, a discussion is presented, concerning their constructive characteristics, operation testing and evaluation of accomplished performance.
