Companies manufacturing defence equipment\u2019s, very often follow standard tests to qualify their designs to ensure proper performance, maintainability and reparability for military application.<\/p>\n

Most Commonly used military standards are MIL-STD-810, JSS55555, MIL-STD-810 A. These are the governing document for production and supply of the equipment.<\/p>\n

In the late 18th century, French and USA militaries were early adopters and long-time development sponsors of standardization. By World War II, virtually all national militaries were on standardizing
\ntheir WAR equipment\u2019s.<\/p>\n

Some countries had to pay for not standardizing their designs, due to differences in dimensional tolerances, in World War II screws, bolts and nuts did not fit the equipment\u2019s properly and were not
\ninterchangeable. Defence standards provide many benefits such as minimizing the number of types
\nof ammunition, ensuring compatibility of tools, and ensuring quality during production of military
\nequipment. This helped in opening ammunition and food cases without any tools, also swapping
\ndamaged vehicle subsystems made faster and easier.<\/p>\n

As per the standard JSS55555 let\u2019s take an example for Vibration.<\/p>\n

The vibration experienced by equipment in the course of transportation and use is generally of a complex nature and is a function of the excitation source. Therefore the objective is to ensure
\nequipment tested to these procedures will be compatible with the actual environmental conditions.<\/p>\n

Below are the interpolated test inputs for harmonic study:<\/p>\n

Physical Test:<\/strong><\/p>\n

For physical test the equipment is mounted on a test rig with the base mountings, and then base is excited at given frequency range for the given constant acceleration for certain duration in all 3\u00a0 derived results are studied by reading the characteristics of the curve obtained. Generally this
\ntest is known as \u201cshakers table test\u201d.<\/p>\n

Virtual Test:<\/strong><\/p>\n

There are software\u2019s in the market to solve the above harmonic problems and validate the same before actually testing the equipment. This gives better understanding on our design when it is
\nsubjected to harmonic loading and also helps us in deciding the best dampers to be used for better
\nperformance and ruggedness of the equipment.<\/p>\n

We have SOLIDWORKS Simulation which tackles the harmonic related problems with fast and very ease according to the specified standards.<\/p>\n

SOLIDWORKS Simulation has an institutive workflow wizard which helps in giving the inputs for harmonic study as per the specifications given.<\/p>\n

SOLIDWORKS Simulation suffices your requirement for performing following Studies:\"Qualifying<\/p>\n
