Abstract
"APARELHO PARA ATENUAçãO DE VIBRAçõES USANDO ATUAçãO ELETRôNICA E ELETROMAGNéTICA". Um sistema de cancelamento de vibração e ruído inclui um atuador de cancelamento de vibração eletromagnético (21) e um sistema de controle eletrônico (16). O atuador de cancelamento de vibração (21) inclui um ímã permanente (6) próximo a um coletor de fluxo (4, 10). O coletor de fluxo tem um vão através do qual o campo magnético do ímã é direcionado. A corrente direcionada para escoar por uma bobina ou conjunto de bobinas (8), enrolada(s) em um molde de bobina (9) dentro do vão, gera um campo magnético, que é usado para movimentar a massa do atuador do coletor de fluxo e do ímã, de modo a criar uma interferência destrutiva de cancelamento de vibração ou ruído. A corrente de acionamento é proporcionada pelo sistema de controle eletrônico (16) e pelo amplificador. O sistema de controle eletrônico recebe as saídas de vários sensores (14, 19, 22), que poderiam incluir as dos sensores de ruído (19) e de vibração (14). Os sensores podem proporcionar informações de ação prévia e de retroação. O controlador pode incluir algoritmos de controle adaptativos."VIBRATION ATTENTION APPARATUS USING ELECTRONIC AND ELECTROMAGNETIC ACTING". A vibration and noise cancellation system includes an electromagnetic vibration cancellation actuator (21) and an electronic control system (16). The vibration canceling actuator (21) includes a permanent magnet (6) next to a flow collector (4, 10). The flux collector has a gap through which the magnetic field of the magnet is directed. Current directed to flow by a coil or set of coils (8), wound (s) in a coil mold (9) within the gap, generates a magnetic field, which is used to move the mass of the flow collector actuator. and magnet to create destructive interference from vibration or noise cancellation. The drive current is provided by the electronic control system (16) and the amplifier. The electronic control system receives outputs from various sensors (14, 19, 22), which could include those from noise (19) and vibration (14) sensors. Sensors can provide pre-action and feedback information. The controller may include adaptive control algorithms.
