| Abstract: | In the process of container handling with cranes, vibrations and impacts can damage substructures of a container such as a sensor holder. To ensure the normal operation of sensor holder during transportation, it is necessary to monitor conditions of sensors and take remediation. A theoretical analysis and experimental measurement are combined to investigate vibrations of the sensor holder of a container structure. The results show that the sensor holder has a large displacement response in the frequency range of 12–25Hz. The sensor holder has a large acceleration response in the frequency range of 4100–5000Hz. A preliminary vibration isolation scheme design can be proposed with the consideration of these two frequency bands, and feasibility analysis and optimization targets are discussed. |
