Vibration Testing

Vibration testing is a method used to simulate the conditions that a product or structure might encounter throughout its life in a controlled environment. Products are subjected to a variety of stresses that can potentially weaken or damage them over time, with vibration being a significant factor. Vibrations are present in nearly all environments, ranging from constant frequency flows to high-energy impacts.

The ability of a product to withstand these stresses is of paramount importance for its durability and reliability. In many industries, compliance with standards is now mandatory in order to guarantee product robustness and performance. Vibration testing is a crucial element in confirming that products remain reliable and safe during operation or transport, thus helping to prevent unexpected performance issues or early failures in the field.

Vibration testing is a valuable tool for manufacturers, as it enables them to assess the quality, reliability, and durability of their products and their components. Such tests may reveal design deficiencies that would otherwise remain undetected during the processes of transportation, deployment, or utilization, such as the impact of a helmet on the ground. Moreover, tests such as those designed to identify buzz, squeak, and rattle (BSR) in vehicle interiors can facilitate the early detection of unwanted noise generation.

In the context of environmental testing, such as Highly Accelerated Lifetime Testing (HALT) and Highly Accelerated Stress Screening (HASS), it is imperative to integrate vibration testing with environmental chambers in order to effectively simulate the effects of rapid heating and cooling. Such tests are frequently employed in the evaluation of industrial and electronic components, medical equipment, and military hardware.

Drop and Shock Testing

The mechanical testing of products also encompasses drop and shock testing. A comprehensive range of tests is available, including those conducted on a specialized shock machine and various drop surfaces. The objective is to provide a comprehensive mechanical testing service in a single location, thus obviating the necessity for clients to visit multiple test facilities. Our experience across a broad spectrum of industries, including industrial and consumer, allows us to provide comprehensive support for your project requirements.

What are the reasons for the importance of vibration, drop, and shock testing?

The implementation of shock and vibration testing offers a multitude of advantages, including:

• It is important to ascertain whether the product in question is capable of withstanding the rigours of real-world conditions.

• It is imperative to adhere to the applicable regulations.

• It is possible to avoid the costly consequences of damage sustained during the transportation process.

• It is imperative to reduce the incidence of returns and defective products.

• It is of the utmost importance to guarantee that the product will remain in optimal condition.

Drop testing is a quality control procedure employed to evaluate the durability of components (such as integrated circuits or audio parts) and materials at the board level (printed circuit board, PCB) prior to mass production. The reliability of electronic components is contingent upon the strength of their connections when subjected to mechanical shock events, such as during handling, shipping, user drops, or collisions. The excessive flexing of the circuit board during these events has the potential to result in product failure.

Drop testing can be used to

• It is imperative to ascertain the dependability of the interconnections between the components at the circuit board level.

• It is essential to evaluate the suitability of different component suppliers in order to ascertain whether they meet the established acceptance criteria.

• It is imperative to ascertain the quality of the components in accordance with the various established standards.

• It is necessary to evaluate the anticipated lifespan of the components in question.

• It is necessary to collate statistical data on the items that have undergone testing in order to make informed decisions regarding their acceptance.

The testing was conducted in accordance with the established standards

A multitude of vibration and drop testing profiles have been delineated by standards that have been developed over an extended period of time. These standards are frequently tailored for particular applications and products. Notable examples include the International Electrotechnical Commission (IEC), the Military Standard (MIL-STD), the Communications Network Standard (CNS), the Global Regulatory Standard (GR-63), the European Telecommunications Standards Institute (ETSI), and the Dell standard. It is of particular importance in the aerospace and defense industries to adhere to the aforementioned standards.
