摘　　要：基于提出的新型变自由度组合柔顺副,构建了具有奇异位置运动确定和力适应复位特征的变自由度柔顺五杆机构。根据不同驱动方式和不同限位边界,该柔顺机构可实现铰链四杆机构、平面五杆机构、曲柄摇块机构和摆动导杆机构4种运动模式及模式间切换。为了单驱动实现电动开启、电动保险,新型柔顺机构构造的电动开启支链通过多运动模式完成汽车门锁的多工况确定运动及复位运动。各工况下柔顺副扭簧中心槽内的漂移量作为机构柔顺适应性指标,可衡量柔顺支链与其他支链的运动兼容性。Based on a proposed novel variable DOF compliant pair,a variable DOF compliant five-bar mechanism was constructed,that had features such as determined motion at singular positions and force-adaptive position recovery.Four motion modes such as pirot four-bar mechanism,planar five-bar mechanism,crank-shaper mechanism,crank-oscillating block mechanism might be switched by different driving methods and limiting stoppers.To deal with the expected tasks of power release and electric lock actuated with one single actuator,the power release branch of compliant mechanism realized the defined motions and position recovery motions of vehicle side door latch in multiple working modes.Kinematic compatibility of compliant branch and other branches might be measured by rotation center drifting displacement,which was as a compliant adaptive measuring index of the mechanism.
