The Kinematic Model Studying of 3-DOF Parallel Massage Mechanism
, 2013 为达到治病疗效,精准的穴位定位和精确控制的按摩力道是足部按摩机器人的关键。将机器人的按摩定位执行机构设计成并联滑块机构,对机构运动学进行建模,并利用MATLAB对所得到的位移、速度进行仿真验证。仿真结果表明:其运动学方程正、逆解和雅可比矩阵均为简洁的显式表达,便于实时控制;按摩触头随滑块的位移与连杆的角度变化作运动 ...

Gaoya dianqi直流组合电器可以将短路故障电流由真空横磁转移开关转移至并联断路器或熔断器上完成开断，在直流配电网中具有应用潜力。为了得到适用于直流组合电器的真空开关触头设计，文中研究了外施横向磁场下真空电弧在卍字型横向磁场触头上稳定阶段的弧隙中磁场分布和电弧受力规律。基于有限元仿真方法，结果显示卍字型横磁触头与外施磁场叠加后将改变电弧附近磁场分布特性，当电弧处于卍字型触头上的某些位置时，其受力特性不利于电弧快速向触头边缘运动。而电弧在越过卍字型触头开槽时受力变化可能使电弧运动偏转，延长电弧的稳定阶段时间 ...
