Do you need to perform acceleration testing of your military products or systems for specific platforms?

Acceleration, as addressed in MIL-STD-810G Method 513.6 (Department of Defense, 2009), is a load factor (inertial load or “g” load) that is applied slowly enough and held steady for a period of time such that the materiel has sufficient time to fully distribute the resulting internal loads to all critical joints and components.

The common methods used to expose equipment to a sustained acceleration load are centrifuge and track/rocket-powered-sled testing.

Acceleration and Shock Tests - Sled Testing. MIL-STD-810H. Sled Testing. Difference beween Shock and Acceleration.


However, both methods impose limitations on AE equipment testing. For example, the costs required and the scheduling, planning, and coordination phases associated with the use of these types of test
facilities are often prohibitive. In some cases, centrifuges and track/rocket sleds may limit the orientations at which the test article can be mounted for testing. To maintain validity, all AE devices are tested under the same mounting configuration as intended for operational use. Finally, due to the often expensive and delicate nature of medical devices, insufficient inventories often prevent the use of these tests due to their somewhat destructive nature.


Because of the difficulties associated with physical dynamic testing, the ATB team initially turned to Finite Element Analysis (FEA) as the method of choice for meeting acceleration test requirements.

Recent technological advances in microcomputing and higher resolution graphics capabilities allowed complex systems to be modeled and simulated for both static and dynamic tests.

The FEA techniques were already used by others for various aircraft structures and devices. For example, Foster and Sarwade (2005) performed an FEA of a structure that attached medical devices to a litter. This structure was later approved as STF. Continuing on the same theme, Lawrence, Fasanella, Tabiei, Brinkley, and Shemwell (2008) studied a crash test dummy model for NASA’s Orion
crew module landings using FEA. Viisoreanu, Rutman, and Cassatt (1999) reported their findings for the analysis of the aircraft cargo net barrier using FEA. Furthermore, Motevalli and Noureddine (1998)
used an FEA model of a fuselage section to simulate the aircraft cabin environment in air turbulence. These and similar studies demonstrated the successful use of the FEA method to verify requirements
by analysis for an acceleration test.

Given the costs associated with dynamic testing, the ATB originally envisioned using the FEA method to alleviate budget and inventory concerns. To test this theory, the ATB employed FEA for testing various AE structures to meet the acceleration requirements and found some aspects of this method to be cost- and time-prohibitive.


Lessons learned from these studies are provided in the case-studies section. The various types of analysis and test methods raise questions as to what the correct decision process is for selecting the most appropriate method for STF testing of AE equipment.

The authors of this article describe the process developed and employed by the ATB for the acceleration testing of AE equipment since June 2008.


The ATB’s process has proven to be well suited for identifying the most appropriate test method—one that not only represents the most appropriate and effective test method, but also minimizes the use of available resources. This process includes testing both structurally simple and complex equipment and successfully introducing the use of the Equivalent Load Testing (ELT) method, which permits
the use of alternative testing approaches, such as pull testing and tensile testing.

About Requirements Management Training

Although this training is not mandatory, it is one of the most important training item in the systems engineering area.

Statistics show that 55% of project failures are due to requirements. Some requirements may have missing information, some are poorly written to understand how they may objectively be tested, or some might include other issues.

The problems in the requirements are usually detected at the end of the project, in testing phase, which may cause your project end unsuccessfuly.

Dr. Cicek studied PhD in Mechanical Engineering Department at Texas Tech University in Texas, USA. He study included random vibration. He has both industrial and academic experience for over 30 years.

He gained engineering and leadership experience in the United States Department of Defence projects and programs as systems development engineer about 15 years. He led the development of various engineering systems for platforms including C-5, C-17, KC-10, KC-135, and C-130 E/H/J.  Dr. Cicek’s experience includes unmanned aerial vehicle development where he utilized the Geographical Information Systems (GIS) and Malfunction Data Recorder Analysis Recorder System (MADARS) development for military transport aircraft.

Dr Cicek worked as the lab chief engineer for five years at the US Air Force Aeromedical Test Lab at WPAFB/OH. He received many important awards at the positions he served, due to the excellent team-work and his detail oriented and energetic personality.  These included Terra Health’s Superior Client Award in 2009 and Engineering Excellence Award in 2010 as well as an appreciation letter from the US Air Force Aeronautical Systems Center (ASC), signed by the commander in charge.

Dr Cicek also established a test lab, called Marine Equipment Test Center (METC) and located at Istanbul Technical University, Tuzla Campus, for testing of equipment per military and civilian standards, such as RTCA-DO-160. Providing engineering, consultancy, and training services to many companies and organizations, Dr. Cicek has gained a great insight into the tailoring of standard test methods in accordance with military standards, guides, and handbooks as well as Life Cycle Environmental Profile LCEP) developed for the equipment under test.

Dr. Cicek also completed various product and research projects, funded in the USA, EU, and Turkey. He is currently teaching at Istanbul Technical University Maritime Faculty, Tuzla/Istanbul. He also manages the Marine Equipment Test Center in Tuzla Campus.

This short training on MIL-STD-810H testing class will provide education in the purpose of each test (with emphasis on CONOPS and LCEP documents), the following:

  • Equipment required to perform
  • Selection of procedures
  • Correctly identifying test conditions
  • Test durations
