在实际的运输环境中,运输包装件总会受到不规则振动的影响,又不免在共振作用的参与下承受着复杂的动态应力。随机振动试验则可用作评定包装件,在承受运输途中随机振动环境时,其内外包装、填装和封固方式等项目的牢固性和保护性的手段。随机振动是一种非线性振动,加上所装货物的运动和其它缓冲因素的影响,因此很难通过试验手段找出其与正弦振动的等效关系。而由于随机振动试验的条件更接近实 In the actual transport environment, the transport package will always be affected by the irregular vibration, but also with the participation of resonance under the complex dynamic stress. Random vibration test can be used as a package to assess, in the transport of random vibration environment, its packaging, filling and sealing methods and other items of the firm and protective means. Random vibration is a nonlinear vibration, coupled with the movement of goods loaded and other cushioning factors, it is difficult to find out by experiment the equivalent relationship with sinusoidal vibration. And because of random vibration test conditions closer to reality
