摘　　要：在日常生活中,输电线路常常扮演着不可或缺的角色,而输电铁塔基础的稳定与否对线路的正常运行至关重要。对基础变形的实验装置进行了模拟设计,装置模型选取少自由度并联机构,三维建模后进行运动仿真,验证了模拟实验的可行性。选取了合适的驱动方式使装置能满足三方向的行程需求,利用实时控制方式的虚拟仿真技术对装置进行控制,并根据模拟条件对装置进行了刚度、强度设计。Transmission lines act an important role in our daily lives. Therefore the foundation of the transmission line towers is essential for the lines＇ running. The foundation deformation experimental simulator was designed, which selected lower-mobility parallel mechanism as device model. With the help of computer software, the feasibility of this device was modeled, simulated and verified. Use appropriate driving method can achieve the route demands in three directions, and, with the advantage of real-time control function based on simulation technology, control issues have been solved, finally, on the basis of working condition, conducted intensity and rigidity design of the device.
