为检验所建立的心血管系统仿真模型,对扩大囊覆盖面积抗荷服(ECGS)的囊覆盖面积及压力制度对人体G耐力及心血管反应的影响进行了仿真实验,得到了与耿喜臣等(1996)离心机实验数据基本吻合的结果。仿真结果表明,ECGS比标准抗荷服能显著提高被试者的松弛+Gz耐力,且在提高耐力的同时,被试者的心率没有明显增加。仿真揭示出ECGS的抗荷性能主要依赖于其囊下血管及组织的压力传递效率。虽然ECGS的抗荷性能随压力制度的增加显著提高,但抗荷服压力制度高于10kPa/G时,这一上升趋势变缓。
To test the established cardiovascular system simulation model, the effect of expanding the coverage area and the pressure regime of ECGS on the G-endurance and cardiovascular response of human beings was simulated, 1996) centrifuge experimental data basically consistent results. The simulation results show that ECGS can significantly increase the subject’s relaxation + Gz endurance than the standard anti-kimono clothing, and at the same time improve the endurance, the subjects’ heart rate does not increase significantly. The simulation revealed that the anti-load behavior of ECGS mainly depends on the pressure transmission efficiency of its subvascular vessels and tissues. Although the anti-load performance of ECGS significantly increases with the increase of pressure system, the upward trend tends to be slowed down when the anti-service pressure system is higher than 10 kPa / G.
