| 目的 研究多精密仪器货物包装减振性能的评价模型。方法 以多精密仪器货物减振系统为例，研究多精密仪器货物在公路运输时共振破损和冲击破损的破损机理，得出货物在共振破损下的减振效率和冲击破损下的冲击破损概率，然后结合各精密仪器的脆值，建立各精密仪器在货物系统中的权重，最后将共振破损和冲击破损概率分别与权重作向量点乘运算，得到共振破损和冲击破损下各仪器减振效果的综合评价结果。结果 算例货物系统精密仪器1在4种激励综合作用下的减振效果最好(0.39)，而在冲击破损中精密仪器1的效果最差(0.21)。结论 精密仪器1的抗共振性能很好，但抗冲击性很差，需要对其减振系统的性能参数进行改进和优化。 |

| The work aims to study the evaluation model for damping property of multi-precision instrument packages. Taking the damping system of multi-precision instruments as an example, the damage mechanism of resonance damage and shock damage during highway transportation of multi-precision instruments was studied, to obtain the damping efficiency under resonance damage and the shock damage probability under shock damage of the goods. Then, the weight of each precision instrument in the cargo system was established by combining the brittleness of each precision instrument. Finally, the resonance damage and the shock damage probability were multiplied (from vector points) by the weight of the instrument, and the results of comprehensive evaluation of damping effects of each instrument under resonance damage and shock damage were obtained. The results showed that the damping effect under the synthetic action of four kinds of excitation of precision instrument 1 of example-based cargo system was the best (0.39), while the damping effect of precision instrument 1 in shock damage was the worst (0.21). The anti-resonance performance of precision instrument 1 is very good, but the shock resistance is very poor, which needs to improve and optimize the performance parameters of its damping system. |
