  • Vibration isolation for engine mount systems using an active hybrid robust controller

    In this paper, a hybrid robust controller is proposed for reducing vibration on single input/single output (SISO) and multiple input/multiple output (MIMO) engine mount systems. The controller is designed to achieve robust stability and fast convergence by using a combination of the filtered-x least mean squares (FXLMS) and H∞ robust control methods. Plant response is identified by a ...

  • Vibration testing of fuel probes

    Aerial Refuelling The American Bell-Boeing V-22 Osprey is a multimission, military, tilt rotor aircraft with both a vertical and short takeoff and landing capability. It combines the functionality of a conventional helicopter with the high-speed cruise performance of a long-range turboprop aircraft. But even though it is long-range, some missions require in-flight refuelling. The V-22 Osprey can ...

  • Vibrating feeders for stockpiling and reclaim

    The expanding applications of vibratory feeders for controlling the flow of bulk materials, and their adaptation for processing requirements, have developed considerable interest in stockpiling and reclaim systems. The general design of these units consists of a material transporting trough, or platform, driven by a vibratory force system. The flexibility and variety of designs is limited only by ...

  • Active engine mounting controller using extended minimal resource allocating networks

    The application of the Extended Minimal Resource Allocation Network (EMRAN) in the field of active vibration isolation for an automotive engine system is presented. As the source of disturbance the engine is mounted on a two passive mounts in parallel with an active force actuator. EMRAN is implemented to control the force actuator and to isolate this disturbance. The characteristic of EMRAN and ...

  • Active force cancellation of a near resonance vibrating system using robust H∞ control

    In this study, the active force cancellation performance of a robust H∞ controller is investigated on a near resonance vibrating system consisting of a rotating machine hard mounted on a flexible base. This configuration and phenomenon can be present in vehicle engine mounts. The model of the vibrating system was first identified experimentally. The uncompensated system frequency response ...

  • Reducing noise levels through engineering controls

      It"s fairly easy to control personal exposure to noise by limiting exposure time or using hearing protectors like ear plugs or ear muffs.  Engineering controls are usually applied to the machinery that produces noise. Imagine a 200 foot x 175 foot manufacturing facility with a 30 foot high ceiling.  In this building are a variety of cut-off saws, grinders, millers and other ...

  • The Power of the Moon

    The influence the moon has on life on earth is disputed. However, during an assignment in Southeast Asia, vibration experts from Sulzer were able to clearly confirm that the moon can even affect pumps. With its broad expertise, the Sulzer team was able to solve an unusual case of vibration. Southeast Asia is a key exporter of LNG (liquefied natural gas) to global markets, and it is ...
