Project Introduction

　　Random vibration test

　　Vibration exists in the whole circulation process of goods, and the vibration test of package is to simulate the dynamic impact of the transport vehicle on the package during the circulation process of the package. The vibration types commonly used in packaging include sinusoidal vibration and random vibration. Sinusoidal vibration is mainly used in the research, development and design stage to find the resonance point and avoid the resonance point for packaging optimization. Random vibration is used in laboratory to simulate vibration during actual transportation. The random vibration is closer to the vibration hazard generated by the actual transportation environment.

　　Vibration standards commonly used in package simulation transportation are ISTA series, ASTM D4169, GB/T 4857 series, GB/T 35774, ASTM D999, ISO13355, ASTM D4728, etc. The vibration frequency range in the simulated transport is generally 1Hz~300Hz, and the energy in the transport vibration is mainly concentrated in the low-frequency region.

　　Vibration from vehicle suspension system, tires, aircraft turbine, air flow, rail, etc. will exist in the whole circulation process. The frequency range of freight trucks is generally 1Hz~200Hz, and that of freighters is generally 2Hz~300Hz. Appendix A in GB/T 4857.23 presents a part of China's steel spring damping truck road random vibration power spectral density curve calculation and test time, appendix B gives the beijing-shanghai railway transportation instance random vibration power spectral density curve, appendix C gives the international related with acceleration power spectrum density of random vibration in the standard test curve and data such as ASTM D4728, ASTM D4169, ISTA procedure A and ISO 13355-3, reference of foreign standard version of the current version. ASTM D4169 gives the spectrum of trucks with three strengths, three grades of rail and three grades of air.

　　Fugang Industrial Testing Services(Suzhou) Co., Ltd. is a professional testing laboratory for packaging and transportation, focusing on ASTM D4169, ISTA 2A, ISTA 3A, ISTA 3E, GB/T 4857 testing, the FTS TEAM strives to select The right packaging for users, and provides positive support for users to actively deal with the packaging requirements of foreign e-commerce companies and product registration and packaging verification.
