Research on Damping Performance of Orchard Fruit Three-Stage Damping Trailer Based on Adams

“…Considering that the long-distance transportation time of the fruit was generally more than 10 hours, combined with the actual situation, the actual transportation time of the simulation test was set to 15 hours. But in order to ensure the accuracy of the test simulation, based on the research of William and the specific situation of this laboratory, the actual vibration time of the test was reduced to 1/5 of the original, that is to say, the vibration time was 3 h ( Kipp et al, 2000). The vibration table adopted the frequency sweep mode, and the relevant debugging data are shown in Table 2.…”

Review Paper on Road Vehicle Vibration Simulation for Packaging Testing Purposes

“…Many have suggested using it as an investigation and design tool rather than a packaging performance test. 5,8,9 The limitations of these standards led to the use of random vibration as a standard road-vibration simulation in the early 1980s, described in standards: ASTM D4728-06R12, 10 MIL-STD-810 F, 11 ISO 13355:2003. 12 These procedures produce random Gaussian vibration from different target power density spectra (PDSs) representing different types of vehicle.…”

“…Once again, this method is criticized, because it does not reproduce the randomness of the road excitation. Many have suggested using it as an investigation and design tool rather than a packaging performance test …”

Effect of Difference in Acceleration and Velocity Change on Product Damage Due to Repetitive Shock

“…To prepare various peak acceleration and velocity change combinations, for drop tests performed with identical drop height, we placed either a corrugated fibreboard (‘A’ flute, LB210/MC120/LB210) or a silicon rubber sheet (density, 0.27 g/cm; compression stress at 25% distortion, 126.1 kPa) at the inner bottom of the box. Both were 5 mm thick.…”
