Leveraging Highly Accelerated Life Testing for Aerospace Products

The margin for error is virtually nonexistent in the rapidly evolving aerospace sector. Aerospace products, from commercial satellites to advanced aircraft systems, must meet the highest standards of reliability and durability. This is where Highly Accelerated Life Testing (HALT) comes into play, offering a transformative approach to testing and ensuring the robustness of aerospace components before they even leave the ground.

HALT is a rigorous methodology designed to push aerospace products beyond their operational limits, identifying potential weaknesses and failure modes that traditional testing methods might miss. By subjecting aerospace products to extreme stress conditions—far beyond what they would encounter in their normal life span—HALT provides invaluable insights into the inherent durability and reliability of aerospace components.

The beauty of HALT lies in its ability to reveal the unknown. It accelerates the aging process, simulating years of wear and tear in a fraction of the time, thereby uncovering latent defects and vulnerabilities. This preemptive identification allows for critical design modifications and enhancements, significantly reducing the risk of costly failures and recalls post-launch.

For aerospace manufacturers, the implications of HALT are profound. It signifies a commitment to excellence and represents a strategic investment in the product’s lifecycle. By integrating HALT into the development process, aerospace companies can confidently navigate the complex landscape of product reliability, ensuring that their products are not just fit for purpose but are built to last.

Vibration Testing Lab for Demanding Military Applications

Vibration Testing for military compliance is a crucial aspect for products aiming to serve in military applications. To ensure that these products can endure a severe military environment, they must undergo rigorous testing at a state-of-the-art vibration testing lab. This process involves defining the environmental life cycle that the product will encounter and then developing and executing a qualification test plan based on specific military standards. Completing these tests and documenting them in a detailed report is integral to achieving military compliance.

Why Perform Military Compliance Vibration Testing?

Military compliance vibration testing is especially crucial for military products integrated into complex and costly systems, where failure can lead to significant consequences. The principle reasons for executing this testing include the following:

  1. Ruggedizing Your Product:  Testing your product to a military standard vibration profile will ensure that it can withstand harsh vibration exposures that it would experience throughout its life cycle.
  2. Evaluating Performance: Military compliance vibration testing ensures that items will perform properly under harsh vibration conditions.  If your component does not function properly, it could cause a failure of a complicated system. 
  3. Reducing Maintenance and Preventing Field Failures:  A robust product will have less or no field failures, reduce downtime and maintenance which is critical for military applications. 

Focusing specifically on vibration testing for military compliance, this article delves into various military standards that are vital in evaluating a product’s durability and ruggedness. These include MIL-STD-167, MIL-STD-202, MIL-STD-750, MIL-STD-810, and MIL-STD-883, each with their specific testing methods for a range of environmental conditions including sinusoidal and random vibration testing.

  • MIL-STD-167 Department of Defense Test Method Standard – Mechanical Vibrations of Shipboard Equipment
  • MIL-STD-202 Department of Defense Test Method Standard for Electronic and Electrical Component Parts
  • MIL-STD-750 Test Methods for Semiconductor Devices
  • MIL-STD-810 Department of Defense Test Method Standard for Environmental Engineering Considerations and Laboratory Tests
  • MIL-STD-883 Department of Defense Test Method Standard for Microcircuits

MIL-STD-167 applies to equipment installed on Navy ships with conventionally shafted propulsion.  MIL-STD-167-1 covers mechanical vibrations caused by unbalanced rotating components of Naval shipboard equipment.  MIL-STD-167-2 is for mechanical vibrations from reciprocating machinery and lateral, longitudinal vibrations of propulsion systems and shafting. 

MIL-STD-202 establishes uniform methods for testing electronic and electrical component parts.  MIL-STD-202 defines component parts to include capacitors, resistors, switches, relays, transformers, inductors, etc.  This standard is intended to apply only to small component parts, weighing less than 300 pounds or having a root mean square test voltage up to 50,000 volts. 

MIL-STD-750 is intended to apply only to testing semiconductor devices.  Semiconductor devices include such items as transistors, diodes, voltage regulators, rectifiers, tunnel diodes, and other related parts.

MIL-STD-810: Vibration Testing Category 4 – Truck/Trailer – Secured Cargo

This is part two of a series of blog posts concerning the MIL-STD 810 Vibration Section.  This blog was written with reference to MIL-STD-810G w/Change 1 dated 15 April 2014.  DES has the experience and expertise to help you determine what profiles are appropriate for your product and to run your MIL-STD-810 vibration test.  For more information, please check out Part 1 – MIL-STD-810 Vibration Testing Overview blog and our Vibration Testing services page.

Category 4 of Method 514.7 Vibration testing details the transportation random vibration environmental conditions from cargo interaction with vehicle suspension and structures with road and surface discontinuities.  “This environment may be divided into two phases, truck transportation over US highways, and mission/field transportation.  Mission/field transportation is further broken down into two-wheeled trailer and wheeled vehicles categories.”

 

Truck Transportation over US Highways Vibration Testing

This vibration test method is used when products or equipment will be transported by large trucks tractor-trailers commonly seen on US highways.  The truck transportation over US highways random vibration profile is designed to simulate 1609 km (1000 miles) on interstate highways.  The random vibration profile along each axis can be seen in the plot below in Figure 1.  The length of this profile is 60 minutes per axis for each 1000 miles of transportation.  For example to simulate 2000 highway miles, the vibration test duration would be 2 hours per axis x 3 axes = 6 hours total.
