【摘要】 在气动伺服系统中,动力机构是其核心。将普通单杆气缸和自制磁流变液(MRF)阻尼器串联设计制作了非对称气-MRF阻尼缸动力机构。并构建了该动力机构的实验台。通过实验,对该动力机构阶跃响应特性进行了分析。实验和分析表明,合理地控制MRF阻尼器的阻尼力则可以获得较常规的气动动力机构更优的静、动态特性。更多还原

【Abstract】 The power mechanism is the core in the pneumatic servo control system. An asymmetric pneumatic-MRF damping cylinder power mechanism was made, connected self-made MRF damper to normal single-pole pneumatic cylinder, and the MR-testing table was made. Through the experiments of the step response, the characteristics of the power mechanism was analysed. The experimental results show the static and dynamical property of the pneumatic power mechanism can be improved by controlling the resistance of the MRF-damper reasonably.更多还原
