摘要： The invention provides a large-amplitude vertical-torsional coupled free vibration device, which belongs to the technical field of vertical-torsional coupled free vibration device for wind tunnel test. The gear blocks are consolidated at both ends of the beam. The screws, beam, and the gear blocks are fixed on the model, and they can fulfil the vertical-torsional coupled free vibration. The toothed plate is attached to the sliding block that iteratively moving along the vertical guide rail which is fixed to the ground. The vertical springs attached to the sliding blocks provide both vertical and torsional linear stiffness for the suspension vibration system. The springs only have vertical linear tensile deformations without any lateral tilt, which ensures the linear vertical and torsional stiffness of the model, and the lateral freedom is effectively restrained. This device can achieve the large-amplitude vertical-torsional coupled free vibration of the model, and the deficiency of the traditional device where springs are apparently tilted and the inefficacy of linear stiffness can be avoided. The lateral vibration is restrained, and it is applicable to large-amplitude vertical-torsional coupled free vibrations.

摘要： A vibration monitoring and analysis system may include a transducer configured to convert sensed vibration into an alternating current. A processing module may analyze the alternating current and produce an output configured to convey information regarding characteristics of the alternating current. One or more analysis modules may be utilized to compare a waveform of the sensed vibration to known patterns, for example to identify known events and/or conditions.

摘要： Provided is a structural health monitoring system of a rotating object such as a turbine blade, which gives easy and intuitive information to field managers on the damage location and the damage size of the rotating object by computing and visualizing correlations between damage and propagating ultrasonic wave. The structural health monitoring system for a rotating object comprises an ultrasonic generation system which generates an ultrasonic signal by irradiating a pulse laser beam to a point of the rotating object, a pulse laser control system which adjusts the irradiating time of the pulse laser beam, an ultrasonic measurement system which measures a generated ultrasonic signal at a point of the rotating object away from the point irradiated by the pulse laser beam and a damage detection system which provides information of damage existence, damage location and damage severity by visualization of monitored ultrasonic signals.

摘要： The mechanical movement includes a checking device which is a passive indicator element. The passive element is fixed to a fixed support portion of the mechanical movement. The passive element may be a strip or a plate fixed to the fixed support portion of a regulating member and configured to vibrate according to one or more clearly defined vibration frequency components following the vibration of the mechanical movement. The vibration frequency components of the strip or plate define an acoustic signature specific to the timepiece to allow the authenticity of the timepiece to be determined by a measurement of the acoustic signature using an acoustic measuring system.

摘要： A vibration source described herein may utilize spinning weights to create vibrations in one or more controlled directions. By placing the two rotating masses in a position along the axis of the tool and counter-rotating the masses, it is possible to cancel the rotational output of the individual spinning eccentric masses and yield a uni-directional linear vibration. The rotation of the masses may also be controlled by a processor to change the direction of the vibration in real-time. Thus, the vibration source may be utilized in geologic interrogation or communications.
