ASTMD358095产品振动实验的试验方法(垂直正弦曲线运动)

ASTM D 3580-95 Standard Test Methods for Vibration (Vertical Linear Motion) Test of Products 产品振动试验的标准测试方法 1. Scope 1.1 These test methods cover the determination of resonances of unpackaged products and components of unpackaged products by means of vertical linear motion at the surface on which the product is mounted for test. Two alternate test methods are presented: Test Method A-Resonance Search Using Sinusoidal Vibration, and Test Method B-Resonance Search Using Random Vibration. 1.2 This information may be used to examine the response of products to vibration for product design purposes, or for the design of a container or interior package that will minimize transportation vibration inputs at these critical frequencies, when these products resonances are within the expected transportation environment frequency range. Since vibration damage is most likely to occur at product resonant frequencies, these resonances may be thought of as potential product fragility points. 1.3 Information obtained from the optional dwell test methods may be used to assess the fatigue characteristics of the resonating components and for product modification. This may become necessary if the response of a product would require design of an impractical or excessively costly shipping container. 1.4 These test methods do not necessarily simulate the vibration effects that the product will encounter in its operational or in-use environment. Other, more suitable test procedures should be used for this purpose. 1.5 Test levels given in these test methods represent the correlation of the best information currently available from research investigation and from experience in the use of these test methods.
