| 中文摘要: |
| 研究编织线材料、生产工艺参数和使用环境对液压制动软管膨胀量的影响。结果表明：编织线材料采用维纶线时，液压制动软管的膨胀量较小，低膨胀性能更加优异；编织张力和编织外径对液压制动软管的膨胀量有一定的影响；随着工作环境温度的升高和使用时间的增长，液压制动软管的膨胀量变大。通过编织线的拉伸应力-应变试验结果解释了编织线材料和环境温度对液压制动软管膨胀量影响的原理。 |
| 英文摘要: |
| The effects of braided yarn material，manufacturing process parameters and usage environment on the expansion of hydraulic brake hose were studied. The results showed that when the braided yarn was vinylon yarn，the expansion of hydraulic brake hose was lower and the low-expansion property was better.The weaving tension and outer diameter had a certain effects on the expansion of hydraulic brake hose. With the increase of ambient temperature and the prolong of service time，the expansion of hydraulic brake hose increased. Through the tensile stress-strain test of braided yarn，the principle of the effects of braid yarn material and ambient temperature on the expansion of hydraulic brake hose was explained. |
