输电线路铁塔基础变形实验系统的设计

Design of an Experimental System for Tower Foundation Deformation Testing

输电线路我们日常生活中扮演着十分重要的角色,而输电铁塔的基础对于线路的正常运行至关重要。对铁塔基础变形模拟实验装置进行了设计,选取了少自由度机构作为装置模型并进行3D建模,之后进行运动仿真,验证了利用该装置来模拟实验的可行性。仿真后选择合适的装置使得驱动方式满足三个方向的行程需求,利用基于虚拟仿真技术的实时控制方式解决了装置的控制问题,并根据使用条件对该装置进行了刚度和强度设计。

Transmission lines are important infrastructure and the foundation stabilityof the transmission towers is essential for the power line safety. This paper presents the design of a foundation deformation experimental simulator, which selectsa lower-mobility parallel mechanism as the device model. With the help of the Pro/E and ADAMS, this paper simulated and finally validated the feasibility of this device. Through the use an appropriate driving method, it can achieve the route demands in three directions. With the advantage of a real- time control function based on the simulation technology, control issues were solved. Finally, on the basis of the working condition, the rigidity design of the device was completed.
