电控气动式可调阻尼减振器的设计与应用

确定了电控气动式可调阻尼减振器在"软"、"硬"阻尼状态下的阻尼力设计目标.设计了以电磁阀和摆动气缸作为驱动机构的电控气动式可调阻尼减振器,通过仿真计算分析了该减振器的阻尼特性.研制了可调阻尼减振器样件并在试验台架上进行了性能测试.结果表明,除后减振器压缩阻力外.其余各项阻尼力试验值与仿真值的平均偏差小于7%,表明减振器的仿真模型有效.将该可调阻尼减振器装车进行的道路平顺性试验表明,与被动式减振器相比,采用可调阻尼减振器可使客车的行驶平顺性得到提高.

Design and Application of Electronic-controlled Pneumatic Adjustable Shock Absorber

The design objectives of electronic-controlled pneumatic adjustable shock absorber under 'hard'and 'soft'damping situation are defined.A new type electronic-controlled pneumatic adjustable shock absorber which adopts solenoid vMve and swing pneumatic cylinder as driving mechanism is designed,and damping characteristic of the shock absorber is analyzed by computation and analysis.Specimen of the adjustable shock absorber was developed and was subjected to damping performance bench test.It is shown that the average deviation of the damping force test values from simulation is less than 7 % ,except for the compression resistance of the rear shock absorber,proving validity of the simulation model.Road rid test with the adjustable damping shock absorber fitted on board indicates that rid comfort of bus equipped with the damping adjustable shock absorber is better than the one with passive shock absorber.
