| 摘要: | 在起重机搬运集装箱的过程中, 振动和冲击会损坏集装箱的底层结构(如传感器支架). 为确保传感器支架在运输时正常工作, 对传感器的状态进行监测并采取相应补救措施. 通过理论分析和实验测量相结合的方式, 对集装箱结构中传感器支架的振动进行了研究. 结果表明, 在12~25Hz频段, 传感器支架有较大的位移响应; 在4100~5000Hz频段, 传感器支架有较大的加速度响应. 因此, 可以针对这两个主要频率区间进行初步隔振方案设计, 并讨论可行性分析和优化目标. |
| 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. |
