适用范围

4.1 Shipping containers are exposed to complex dynamic stresses when subjected to vibration present in all transportation vehicles. Approximating the actual damage, or lack of damage, experienced in shipping may require subjecting the container(s) and contents to vibration inputs.

4.2 Resonant responses during shipment can be severe and may lead to package or product failure. Identification of critical frequencies, and the nature of package stresses can aid in minimizing the effect of these occurrences.

4.3 Vibration tests should be based on representative field data. When possible, the confidence level may be improved by comparing laboratory test results with actual field shipment data. It is highly recommended that one understand the most common failures to one’s products and packaging in distribution, and then attempt to replicate those failures in the laboratory. Once such replication is established, then that test can become the minimum necessary test for future packaged products to pass.

4.4 Exposure to vibration can affect the shipping container, its interior packaging, means of closure, and contents. These tests allow analysis of the interaction of these components. Design modification to one or more of these components may be utilized to achieve optimum performance in the shipping environment.

4.5 Methods A1 and A2, Repetitive Shock Tests, are suitable for tests of individual containers that are transported unrestrained on the bed of a vehicle and may be suitable for tests of containers that might be subjected to repetitive shocks due to magnification of vibrations in unit loads or stacks.

Note 1: Methods A1 and A2 produce different vibration motions, and therefore, will generate different forces which may result in different damage modes and intensities. Results from these two methods may not correlate with one another.

4.6 Method B, Single Container Resonance Test, tests or determines the ability of an individual container and its interior packaging to protect the contents from transportation vibration, particularly when the container and its contents might exhibit resonant responses.

Note 2: Individual products that are palletized might be better tested using Method C.

4.7 Method C, Palletized Load, Unitized Load or Vertical Stack Resonance Test, covers the determination of the presence and the effects of resonance in palletized loads and multiple-unit stacked loads, and whether or not the strength of the containers is sufficient to withstand dynamic loads when stacked.

4.8 Any or all of these test methods may be employed, as determined by the appropriate performance specification, with test intensities, frequency ranges, and test durations as call......

包装纸箱运输振动试验机介绍

一、原理：包装纸箱运输振动试验机是根据美国及欧洲运输标准，并参照美国同类设备改进制造。利用偏心轴在旋转中产生椭圆形的运动轨迹来模拟汽车或轮船运输过程中货物产生的振动，碰撞。将测试平台固定在偏心轴承上，当偏心轴承转动时，测试平台的整个平面就会产生椭圆形的上下前后运动，调整偏心轴随转动速度相当于调整汽车或轮船的行驶速度。...
