| 目的 降低微波炉及其内部元件因运输过程中的振动冲击而受到损坏或发生故障的可能性。方法 分析微波炉产品的结构特征，研究微波炉产品包装系统的隔振缓冲性能，建立六自由度包装系统（包括沿着x，y，z等3个方向的平动以及绕着x，y，z等3个方向的转动）的隔振缓冲力学模型及动力学方程。结果 采用计算机数值模拟的方法对隔振系统的振动响应进行模拟计算，得到加速度峰值为1.1131 m/s2；在理论建模的基础上，制作了微波炉包装系统的实验装置，通过振动实验得出实际加速度峰值为1.2901 m/s2，与计算机模拟结果的误差为11.08%，误差在工程允许范围内。结论 提出的包装系统隔振缓冲设计和评价方法理论可靠，能为微波炉产品的隔振缓冲包装设计提供理论依据和有效参考。 |

| The work aims to reduce the possibility of damage or failure for the internal components in the microwave oven during transportation due to vibration. The structural characteristics of microwave oven products were analyzed. The vibration isolation-buffer performance of microwave oven product’s packaging system was studied. The mechanical model for the vibration isolation-buffer performance of packaging system with six degrees of freedom (including the horizontal motion along x, y and z and the rotation around x, y and z) and the dynamic equation were established. The vibration response of the vibration isolation-buffer system was simulated by computer numerical simulation, and the acceleration peak value obtained was 1.1131 m/s2. Based on the theoretical modeling, the experimental device of the microwave oven product’s packaging system was made. The actual acceleration peak value obtained from the vibration experiment was 1.2901 m/s2. The error was 11.08% compared with the result of computer simulation, which was within the allowable error range of the project. The proposed vibration isolation-buffer design and evaluation method for packaging system is theoretically reliable, which can provide theoretical basis and effective reference for the design of vibration isolation-buffer design of microwave oven products. |
