探讨了将氮气封入车间纵向减振器的可能性,通过理论分析、加载试验和实车试验,表明新开发的气体封入式减振器通过改善油压缩性和阻尼特性,能提高列车微振幅领域的吸能效果,可提高乘坐舒适度1dB～1.5dB。
The possibility of enclosing nitrogen in the longitudinal shock absorber of the workshop was discussed. The theoretical analysis, loading test and real vehicle test indicated that the newly developed gas-filled shock absorber can improve the field of train micro-amplitude by improving the oil compressibility and damping characteristics The energy absorption effect, can improve ride comfort 1dB ~ 1.5dB.
