摘　　要：针对ITER部件转运车的特殊需求,设计和分析了用于车厢姿态调整的3自由度并联平台。该平台由运动平台、固定平台、球形关节、虎克铰、连杆等组成,具有刚度大,结构稳定、承载能力强、误差小、位姿精度高等优点。论文详细论述了3自由度并联平台的机构设计、自由度计算和关键部件有限元分析。分析结果表明,该3自由度并联平台满足ITER部件转运车车厢对接需求。A 3-DOF（degree of freedom） parallel platform for cask attitude adjustment was designed and analyzed according to the special needs of ITER transfer cask. The platform was made up of a motion platform, fixed platform, spherical joints, the hooke joints and connecting rods, which had merits of high stiffness, structural stability, strong load capacity, minor error and high posture precision and so on. A detailed discussion was carried out on mechanism design, finite elements analysis for key components and DOF calculation. The results show that the 3-DOF parallel platform can meet the demands of the ITER transfer cask.
