| 先用单因子试验研究气囊帘线材质、帘线角度和帘线膨胀比对自由膜式空气弹簧静态性能（水平静态刚度、垂向静态刚度和载荷内压）的影响，再用正交试验法分析这3个因子对空气弹簧静态性能的影响程度。结果表明，气囊帘线材质、帘线角度和帘线膨胀比对空气弹簧静态性能均有不同程度的影响，其中帘线材质对空气弹簧载荷内压的影响程度最大，帘线角度对空气弹簧垂向静态刚度的影响程度最大，帘线膨胀比对空气弹簧水平静态刚度的影响程度最大。 |
| 英文摘要: |
| A single factor test was used to study the influence of the airbag cord materials，cord angles and cord expansion ratios on the static performance（horizontal static stiffness，vertical static stiffness and load internal pressure） of the free diaphragm air spring，and then the orthogonal test method was used to analyze the influence degree of these three factors on the static performance of the air spring.The results showed that the airbag cord material，cord angle and cord expansion ratio had different influence degrees on the static performance of the air spring.Among them，the cord material had the greatest influence on the load internal pressure of the air spring，the cord angle had the greatest influence on the vertical static stiffness，and the cord expansion ratio had the greatest influence on the horizontal static stiffness. |
