Course Description

This 4-day class will provide education in purpose of each test, the equipment required to perform each test, and the methodology to correctly apply the specified test environments.

Vibration and Shock methods will be covered together and will include an overview of Sine and Random Vibration as well as classical waveform shock testing, drop testing and Shock Response Spectrum Testing. Instrumentation, vibration equipment, control systems and fixture design will be covered.

Each climatic test will be discussed individually, focusing on requirements, origination, equipment required, test methodology and understanding of results. Class members will participate in a tour of a lab that daily performs the full spectrum of 810G tests.

Discussion, supported by projected visuals and video clips. Commencing with a review of basic vibrations, we will explore vibration measurements and analysis. We’ll compare sinusoidal vs. random vibration testing systems, specifications, standards and procedures. We will emphasize vibration and shock test fixture design, fabrication, experimental evaluation and usage. We will study shock measurement, shock response spectrum (SRS) and shock testing. 

Climatic testing will be looked at in great detail, emphasizing required equipment and instrumentation, correct interpretation of specifications and hints to ensure that the tests are brought to a successful conclusion.

The course emphasizes topics you will use immediately.  Suppliers to the military services protectively install commercial-off-the-shelf (COTS) equipment in our flight and land vehicles and in shipboard locations where vibration and shock can be severe. We laboratory test the protected equipment (1) to assure twenty years equipment survival and possible combat, also (2) to meet commercial test standards, IEC documents, military standards such as STANAG or MIL-STD-810G, etc. Few if any engineering schools teach about such protection or such testing. Hence this specialized course.

Comparison of 810 Revisions
810G is the latest revision. It has been revised roughly every 8 years since 810 was introduced in 1962 (it was 8 years old when 810A appeared). Some of the earlier revisions are occasionally cited in procurement contracts. Steve will touch upon all the Test Methods in the final column of this available for download PDF file  as well as discuss commonly specified older ones.

Objectives

After this short course, you will be able to:

• perform vibration, shock and climatic tests

• evaluate and select equipment to perform testing

• convert field measured data into a test program

• interpret vibration and shock test requirements and results

• supervise vibration, shock and climatic tests

• specify and experimentally evaluate vibration and shock test fixtures
  

When you visit a test lab or review a test program, you will have a good understanding of the requirements and execution of dynamics and climatics tests and so be able to ask meaningful questions and understand laboratory personnel responses.

For whom intended

This class is aimed at people who need to perform, witness or specify environmental testing in accordance with MIL-STD-810.

It covers all of the Dynamic and Climatic tests described in MIL-STD-810. Are you saying to yourself “I need practical knowledge about MIL-STD-810 testing because my work requirements are:

• My title may be mechanical engineer, mechanical designer or packaging engineer. I design (ruggedize) products that must pass MIL-STD-810 testing. I design products to dynamic and climatic requirements, which I don't fully understand. Then I send a prototype to our lab for testing. I really don't understand what our lab does. I'd better find out.

• I write contracts for or specifications procuring military equipment. I need to understand the requirements of MIL-STD-810. How do I insure that potential contractors understand and will correctly implement the requirements?

• I need to witness and approve testing that is specified to be performed “in accordance with MIL-STD-810”. How do I know if the test equipment proposed is capable of doing the job? How do I know if the data I am given is accurate?

• I work in an environmental test lab. We need to perform tests “in accordance with MIL-STD-810”. How do we perform these tests? How do we interpret the requirements? What in heck is g2/Hz?

• I have been tasked with procuring equipment to perform tests “in accordance with MIL-STD-810”. How do I know I am specifying the right shakers, shock test machines, chambers?

If you thought, "aha - that's what I'm supposed to do" to any of the job descriptions listed above, then instructor Steve Brenner says, "This course is intended for you." It will help you move up your own "learning curve."

A smaller group, for whom the instructor also intends this education: supervisors of any of the above listed activities. Perhaps you were thrust into this responsibility without adequate training. Maybe your predecessor had no opportunity to alert you to potential difficulties. You certainly need to know what your people are talking about. Possibly you had no formal training for your present responsibilities. You need to explain your department's activities to your superiors in the technically correct language. Perhaps you need to decide between "in house" and "outside" testing.

Text Materials
Instructor Steve Brenner has prepared a highly valuable 3-ring binder. On each of the 20 climatic test methods, Steve defines terms, provides such commentaries as “What can go wrong during this test?” He gives the purposes of that test, suggests products on which that test is appropriate and identifies the service environment being simulated. He explains what weaknesses that test can reveal. He identifies what is being controlled during that test and how that control is effected. He deals with the possibility of accelerating that test.

Because many of those just entering climatic testing have not seen very many (if any) climatic test chambers, Steve has provided numerous pictures of general purpose and special purpose chambers, such as Solar Radiation and Rain. In addition to what might be called “catalog photos” of chambers, Steve shows their construction via photos of chamber.

Each participant will also receive a copy of Wayne Tustin's text 'A minimal-mathematics Introduction to the Fundamentals of Random Vibration and Shock Testing, HALT, ESS & HASS, also Measurements, Analysis & Calibration', including a CD containing a number of video clips pertaining to sine and random vibration and shock behavior and testing.
