KC India Testing Laboratories is one of the best and renowned Vibration Testing laboratories. Vibration testing is performed to examine the response of a device under test (DUT) to a defined vibration environment. The measured response may be ability to function in the vibration environment, fatigue life, resonant frequencies or squeak and rattle sound output (NVH).
Our Vibration Testing Labs is exclusively carried out closed-loop. By using accelerometers on the shaker and optionally on the Device under Test, we have high confidence knowing exactly what energy we impart on your unit. Our controller then compensates in real-time for any changes in the entire system ensuring we achieve the specified, nominal test values. We have highly customizable Vibration table is compatible with many different configurations. A shaker head and slip plate. Our systems can accommodate 60 or more data channels and still give you the data right at the end of the test with a formal report following in less than two weeks.
Vibration testing, the vibration environment to which products will be exposed to in real use is reproduced. Products are tested in this environment to judge their durability or check for improvements. Vibration Testing is performed to examine the response of a device under test (DUT) to a defined Vibration Environment. The measured response may be ability to function in the vibration environment, fatigue life, resonant frequencies or squeak and rattle sound output. Squeak and rattle testing is performed with a special type of quiet shaker that produces very low sound levels while under operation. In general, vibration testing is used to demonstrate a product's ability to resist dynamic loads without losing critical functional or structural integrity under specified loads. It can be used to identify accumulated stress effects, and the resulting mechanical weaknesses and performance flaws. Choosing the right Vibration Testing Lab helps ensure that products can safely withstand the vibration levels they experience throughout their service life, ensuring product quality and safety.
Free vibrationoccurs when a mechanical system is set in motion with an initial input and allowed to vibrate freely.
>Forced vibration> is when a time-varying disturbance (load, displacement, velocity, or acceleration) is applied to a mechanical system.
Damped vibration When the energy of a vibrating system is gradually dissipated by friction and other resistances, the vibrations are said to be damped.
The mounting of a vibration sensor (accelerometer) directly impacts on its performance. Incorrect mounting may give readings that relate not only to a change in conditions but also to the instability of the sensor itself – therefore making the sensor’s readings unreliable. As such, correct mounting of a vibration sensor is vital to ensure true readings. To detect any faults in machine components, vibrations sensors should be mounted in locations that ensure horizontal, vertical and axial movement are measured effectively:
• For horizontal measurement, vibration sensors should be mounted on the motor bearings and pump bearings. This measures velocity mm/sec (Peak or RMS) to detect unbalance, and problems with structural rigidity and/or foundation.
• For vertical measurement, sensors should be located on the motor and pump drive end bearings. This measures velocity mm/sec (Peak or RMS) to detect looseness and problems with structural rigidity and/or foundation.
• For axial measurement, sensors should be attached to the motor and pump drive end bearings. This measures velocity mm/sec (Peak or RMS) to detect misalignment between the motor and the fan.
Accelerometers should be mounted onto a surface that is free from oil and grease as close as possible to the source of vibration. The surface should be smooth, unpainted, flat and larger than the base of the accelerometer itself. For best results, sensors should be mounted via a drilled and tapped hole directly to the machine housing.
The Vibration Test Labs is generally intended to simulate the expected real-world vibration in typical or worst-case applications. Usually, the test severity is substantially higher than typical real world vibration levels. This is done in order to do a test in hours, days or weeks that simulates years of product life. This includes tests such as Highly Accelerated Life Tests (HALT) that are much more severe than even the worst-case vibration expected in the real-world. And there are more modest tests such as Environmental Stress Screening (ESS) which is done to weed out weak units that would fail early in real-world operation, and then ship to customers only those units that demonstrate their hardiness by surviving a test that is sufficiently mild that it does not seriously reduce the product’s expected remaining life.
Although the test amplitude is typically higher than the expected real world amplitude, the shape of the Vibration Test signal is intended to closely follow the actual signal shape expected. For example, to simulate the vibration expected for equipment mounted on a wall inside a helicopter, one might test with simultaneous sinusoidal vibration at the frequencies associated with the rotation of the helicopter rotor blades, superimposed on a random vibration covering a wide frequency range associated with how the helicopter structure vibrates due to other vibration sources.
