The interior noise of a vehicle has a significant impact on the customer experience. Any noise outside the norm can raise concerns and discredit the company’s reputation. Engineers have a solid understanding of the noise requirements for internal combustion engine (ICE) vehicles, but electric vehicles (EV) require new standards. As EVs do not have an engine that makes noise, many normal vehicle disturbances are now audible to the passenger.
Many products will experience shock vibration during shipping and handling or in use. These shocks may be infrequent, such as an accidental drop or repetitive, as with transportation over rough road conditions. Vibration test engineers use shock testing to simulate these conditions in the lab and confirm the structural integrity of the device.
Vibration Research designs and manufactures leading edge vibration control systems for all brands of electrodynamic and servohydraulic shakers, as well as portable dynamic signal analyzers. Vibration control systems include hardware vibration controllers and the vibration control software, providing a multi-point control of complex structures, all with an intuitive user interface and easy setup.
If you’re designing the packaging for a new product or a rebranding, you probably want to know how safe your goods will be and how customers will react to your packaging before you invest in a final design. With packaging testing, you can both satisfy consumer sentiment and choose the right packaging design for your product from the safety point of view.
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.
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 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.
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.
