Stiffness can be considered of primary importance in order to guarantee the successful use of any robotic system for a given task. Therefore, this paper proposes procedures for carrying out both numerical and experimental estimations of stiffness performance for multibody robotic systems. The proposed numerical procedure is based on models with lumped parameters for deriving the Cartesian stiffness matrix. Stiffness performance indices are also proposed for comparing stiffness performance. Then, an experimental procedure for the evaluation stiffness performance is proposed as based on a new measuring system named as Milli-CATRASYS (Milli Cassino Tracking System) and on a trilateration technique. Cases of study are reported to show the soundness and engineering feasibility of both the proposed numerical formulation for stiffness analysis and experimental validation of stiffness performance.

为了研究悬索桥中桥塔刚度对悬索桥整体刚度的影响,以西堠门大桥为原型,采用西南交通大学编制的桥梁非线性计算软件BNLAS建立了双塔单跨悬索桥计算模型,该计算模型中跨主缆的跨度为1 650 m,加劲梁为单跨简支结构体系。通过比较不同桥塔刚度(相对原型的0.7,0.8,0.9,1.0,1.1,1.2及1.3倍)情况下悬索桥受力的变化,分析桥塔刚度对悬索桥受力的影响。同时,随着越来越多的多塔多跨悬索桥的建造,笔者也研究了中间桥塔刚度变化对多塔多跨悬索桥受力的影响。
