CME Centrifugal Constant Acceleration Tester

Overview of constant acceleration test 

The performance of product, in addition to its own inherent technological advancement, adaptability to the use environment, reliability and environmental resistance during actual use and transportation are components that cannot be ignored that affect the performance of military equipment. In order to improve the technical level of military equipment and improve the reliability of military equipment, various reliability tests for military equipment have been extensively carried out in the development and production of equipment, including dynamic constant acceleration tests.

Any product has to go through various links such as production, circulation, and use. Products installed on transportation vehicles, aerial vehicles, rotating machinery and projected objects must work under conditions of large constant acceleration. Whether it can work normally under the predetermined constant acceleration conditions must be assessed through certain experiments. The constant acceleration will cause the inertial force of the flying mass, which makes the aircraft, spacecraft and carrying objects appear overweight or weightless.

Different products, similar products with different structures, to determine and compare the pros and cons of their ability to resist constant acceleration, a method must be used for comparison and evaluation. Therefore, assess whether the structure of the product is damaged under high acceleration conditions, and verify the integrity of its structure through tests. In abnormal use, such as forced landing of airplanes, emergency braking of vehicles, ships, etc., the constant acceleration value is abnormal. At this time, whether equipment, parts and components fall off, causing injury to the occupants and hindering the normal operation of their safety and life-saving equipment, must be passed test to verify its crash safety.

Why do constant acceleration test

IEC 60068-2-7, MIL-STD-810 and MIL-STD-202, MIL-STD-883, MIL-STD-750 all take steady-state acceleration (constant acceleration) test as one of the key tests of electronic equipment.

IEC 60068-2-7

To prove the structural suitability equipment and other electrotechnical when subjected to forces produced and the satisfactory performance of components, products, hereinafter referred to as “specimens”, by steady acceleration environments (other than gravity) such as occur in moving vehicles, especially flying vehicles, rotating parts and projectiles, and to provide a test of structural integrity for certain components.

MIL-STD-810 Test Method 513

The acceleration test is performed to assure that materiel can structurally withstand the steady-state inertia loads that are induced by platform acceleration, deceleration, and maneuver in the service environment, and function without degradation during and following exposure to these forces. Acceleration tests are also used to assure that materiel does not become hazardous after exposure to crash inertia loads.

This test method is applicable to materiel that is installed in aircraft, helicopters, manned aerospace vehicles, air-carried stores, and ground-launched missiles.

MIL-STD-883 Test Method 2001

This test is used to determine the effects of constant acceleration on microelectronic devices. It is an accelerated test designed to indicate types of structural and mechanical weaknesses not necessarily detected in shock and vibration tests. It may be used as a high-stress test to determine the mechanical limits of the package, internal metallization and lead system, die or substrate attachment, and other elements of the microelectronic device. By establishing proper stress levels, it may also be employed as an in-line 100 percent screen to detect and eliminate devices with lower than nominal mechanical strengths in any of the structural elements.

MIL-STD-202 Test Method 212

This test is performed for the purpose of determining the effects of acceleration stress on component parts, and to verify the ability of the component parts to operate properly during exposure to acceleration stress such as would be experienced in aircraft, missiles, etc. Unless otherwise specified, the acceleration test apparatus shall be the centrifuge-type and shall be capable of subjecting the test specimen to the value of acceleration (g’s) as specified in.

MIL-STD-750 Method 2006

The constant acceleration test is used to determine the effect on semiconductor devices of a centrifugal force. This test is an accelerated test designed to indicate types of structural and mechanical weaknesses not necessarily detected in shock and vibration tests.

Its basic structure is to load the shaking table on the rotating arm of the centrifuge, so that the sample is subjected to the centrifugal constant acceleration test at the same time during the vibration test.
