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 measurement is complex because of its many components: displacement, velocity, acceleration, and frequencies. Vibration measurement is an effective, non-intrusive method to monitor machine condition during start-ups, shutdowns and normal operation. Regular vibration monitoring can detect in a power plant shaft lines, deteriorations and defects of a number of various structural mechanical conditions, for example cracks, bearing faults, coupling damage, imbalance as well as interruptions in the electric grid.
Vibration measurements are commonly considered to be a sound indicator of a machine’s overall health state (global monitoring).The general principle behind using vibration data is that when faults start to develop, the system dynamics change, which results in different vibration patterns from those observed at the healthy state of the system monitored.
Belt conveyors are an integrated transmission and carrying mechanism with length sometimes extending several thousand meters. In traditional design and analysis of belt conveyors, vibration and impact are usually ignored and only static design is considered. However, to ensure the safety of conveyor operation for this restricted analysis, designers must increase the safety factor, which increases production costs. Many research groups have conducted dynamic analysis of large belt conveyors to reduce production cost and optimize conveyor performance. The conveyor belt was first modeled as an elastic body and then a viscoelastic body to incorporate viscoelastic characteristics of belt cover layer.
If your company makes planes, trains, automobiles, medical devices, computers, and communication systems, or you are a large electronic device supplier, the reliability of your products in the field is crucial to your business success. The growing market for electric and hybrid vehicles is increasing the pressure on life-time performance of the devices that power them.
Torsional vibration measurements allow engineers to better understand the dynamics of their rotating equipment, enabling them to troubleshoot and/or validate performance. With a better understanding of the reasons and methods to measure torsional vibration, the right instrumentation, and a helpful partner, you will become better positioned to make the decisions you need to decrease downtime and increase productivity.
Vibration analysis is the most prevalent method used to monitor the levels and patterns of vibration signals within a component, machinery or structure, in order to detect abnormal vibration events and then using that information to analyse and evaluate the overall condition of the component, machinery or structure. In short, vibration analysis helps you monitor and detect issues using vibration data
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.
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.
In today’s business landscape, in order to survive this COVID-19 situation, plant owners/operators are looking for ways to change how they work. They are looking at the latest form of compact-equipment technology: remote control. For example, do you know what do bicycle helmets, toilet seats, and military drones have in common? Well, all three can be better and easier to use using remote control technology.
If you thought that only rusty hand tools can be restored then guess what? Your shaker can be rejuvenated too because rust is removable. Over time, iron and steel exposed to oxygen and moisture form a chemical reaction called oxidation. Rust is that ugly brownish-red that coats tools, bikes, hair link fences, and other metal goods, including your shaker.
