Active Vibration & Noise Control

Waves possess energy. The algorithm for active control is as follows. Energy, expressed as amplitude, flows over time, indicated by positive and negative values. When a positive value and a negative value meet at the same time, they form a wave and are equal to zero. Noise and vibration are also waves. https://contents.premium.naver.com/bisope/visope/contents/250219074909877vg

 

Shock and Vibration

The role of each element in this shock-vibration damping mechanism is explained and related common sense and knowledge are summarized as follows: 1. The sash spring is installed between the vehicle body and the wheels and converts the shock from the road surface and wheels into vibration. 2. Among the springs in the chassis, coil springs handle vertical movement, while torsion bars handle left-right torsional vibration. https://contents.premium.naver.com/bisope/visope/contents/250226080220187du

 

Move Your Neck Freely!

It's undeniable that engineering exists to design, calculate, and predict the movement of objects. First, the definition of "degrees of freedom"—the coordinate system that expresses the movement of an object. While the probability of this movement following these coordinates isn't extremely high, it can at least be expressed using these coordinates. Now, let's move our necks freely, thinking like an engineer. https://contents.premium.naver.com/bisope/visope/contents/250228081352553mz

 

Accelerometers are most commonly used for vibration measurement.

Accelerometers aren't always required to measure vibration. Displacement sensors and velocity sensors are also available. These sensors are so named because of the units of amplitude they output (displacement-velocity-acceleration), but the amplitude output must be expressed in terms of force, energy, or stress. https://contents.premium.naver.com/bisope/visope/contents/250227073528116aq

BISOPE series 95- Acceleration sensor (ICP)---------------------------------------------------------------------------------------------------------

The amount of charge generated from the transducer (sensor; converter) must express a subtle difference, so careful attention is required in the detailed measurement path. In particular, noise due to cable noise or installation errors can lead to fatal measurement errors. Recent measurement methods are more compact and accurate, and often include self-verification.

In particular, the external amplifier (charger type) system used in the past used an amplifier in the middle to amplify the small amount of charge and use it.

BISOPE series 90 Optimal Sensor Location Selection for Condition Monito...

BISOPE series 90- Optimal Sensor Location Selection for Condition Monitoring Measurement-----------------------------------------------

In order to monitor the condition of a target (machine, structure), installing the optimal sensor in the optimal location is the most important basic requirement. In particular, in the case of vibration monitoring, when the number of given sensors is limited or the location where the sensors can be attached is limited due to the characteristics of the structure, the optimal sensor location selection becomes even more important.

At this time, an important general level selection method is to distinguish the most vulnerable part, sensitive part, and representative part when a load is applied.

 

Theory and practice of optimal vibration sensor location selection

 

Theoretically, there are the following basic princi..............

BISOPE series 84- Accelerometer calibration method----------------

Accelerometer is the most commonly used sensor for vibration measurement. It converts the vibration unit (displacement, velocity, acceleration) into a value (voltage, current) proportional to acceleration and outputs it, so it is also called ‘Acceleration pick up’ or ‘Transducer’. When purchasing a new acceleration sensor, you receive data on the calibrated sensitivity from the manufacturer and input the data into the measuring instrument (FFT, Machine analyzer) to measure it. The standard sensitivity is 10mV/g, 20, 100, 200, 1000, etc., and the calibrated sensitivity is indicated as 0.97mV/g, 19.8, 99,197, 998.5, etc. Even if it does not significantly violate the error of general measurement, calibration is absolutely necessary for precise measurement.

BISOPE series 61- Measurement direction and location of vibration sensor (casing type) (selection method)

-----------------------------------------------------------------------------

Even if there are measuring instruments and vibration sensors, if you want to measure the vibration of a target structure or facility (machine), where and in what direction should you attach the sensor and acquire data? It can be overwhelming. In fact, there must be prior knowledge with a lot of theoretical and empirical basis. Selection and setting of measuring instruments and sensors are important, but data that is not measured in the right location becomes the basis for error diagnosis. To summarize, the answer would be ‘a point where the highest vibration state (position, direction, behavior) can be read well, so evaluation is possible and it is safe.’
