Vibration Resistance of Electrical Equipment

Vibration Resistance of Electrical Equipment

Shock and vibration resistance gives information concerning the robustness of the mechanical design of a device. The methods for evaluating the vibration resistance are defined in IEC 60068-2-6 and IEC 60068- 2-64. Electrical and electronic equipment are exposed to vibration in many applications and must withstand this without any degeneration, or even failure, in their function. Therefore, manufacturers of electrical and electronic devices put a great deal of effort into ensuring their instruments are prepared for such applications.

Automatic Thermal Model Calibration

This helps engineers to better optimize electronics thermal design for reliability, reducing field failures, and to reduce overdesign-linked costs.

Random Vibration Testing

Random Vibration Testing

Random vibrations are the oscillations of mechanical systems excited by environments that vary randomly in time and, perhaps, space. Practically all real physical systems are subjected to random dynamic environments, and many systems will fail due to the effects of these exposures.

Different Types of Calibration

Different Types of Calibration

Measurement equipment calibration can be carried out on different types of instruments across different sectors. Electrical calibration refers to the process of verifying the performance of any instrument that measures or tests electrical parameters such as: voltage, current, resistance, inductance, capacitance, time and frequency. Mechanical instruments are subject to drift due to regular usage, mechanical shock and exposure to varying atmospheric conditions, as such mechanical calibration is needed.

The benefits of An Accredited Calibration Services Laboratory

The benefits of An Accredited Calibration Services Laboratory

The benefits of calibration include improving safety as well as saving money and increasing profitability by avoiding the costs of false acceptance and rejection of products, increasing production efficiency, and extending the life of the equipment. Since the standards of accredited calibration labs are set really high, you can be confident of the accuracy levels of the calibrations.

Sine Vibration Testing

Sine Vibration Testing

Sine Vibration Testing may be considered as the most basic vibration testing method used. This type of vibration testing requires less complex parameters compare to other type of vibration testing. Knowing the nature of sinusoidal signal, makes this type of vibration testing easier to understand and to get familiar with. Though, easier to understand does not make it less important compare to other type of vibration testing. Sine vibration testing may still be at the top rank when we are thinking of dynamic characteristic measurement.

Factors That Affect The Accuracy of Measurements

Factors That Affect The Accuracy of Measurements

Instrument calibration ensures that the instruments perform with high accuracy without compromising the final quality of the product. They perform best when they are calibrated following the manufacturers’ recommendations. Several factors may affect calibration, which will further affect the end quality, rendering the objective of calibration useless. Three of these factors are discussed in this article.

Definition of Reliability and Validity

Definition of Reliability and Validity

Reliability and Validity these two terms are sometimes used interchangeably in research and evaluations. Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.

Limitations of Existing Vibration Testing Systems

Limitations of Existing Vibration Testing Systems

The high force shaker (>70kN typically) vibration testing system is unable to handle larger test article and mass. The CG of such test articles cannot be easily controlled which can result in high overturning moment and causes great stress to the ball bearing assembly.

Running Test with Shock Test Machine

Running Test with Shock Test Machine

Running shock test by using Electrodynamic Shaker may be much more convenient for test engineer due to the close loop control process. Since test engineer can define the shock test profile easily and leave the vibration controller to handle the close loop process by itself.
