The results of testing demonstrate that this mechanism has the advantages of both spring and airdamper mechanisms.
试验结果表明：并联式微震机构兼有弹簧式和气垫式微震机构的优点。

For the catenary structure and train hard across the characteristics of the wind speed train theory and design method, was proposed for the structure of hard across the train airdamper set formula.
Damper: both gas flow regulating button and wind board are high grade PP material, connected with 304 stainless steel bar, manually adjust the outside valve knob, control air flow.
