链传动中松边垂度和张力变化的分析方法
To explore the nonlinear mechanic behaviors of pre-stressed greatly cross structures with CFRP cables under different conditions and provide some reference to the control method of corresponding mechanic behaviors and the practice of corresponding structures,the characters of CFRP cables in static parameters such as equivalent stiffness,vertical component of forces,sag effects were analyzed.
为了探索碳纤维(CFRP)索预应力大跨结构在不同条件下的非线性力学行为,并为相应力学行为的控制及相应结构的开发应用提供依据,对CFRP斜拉索的静力特性参数如切线刚度、竖向分力、垂度等计算公式进行了推导,并与传统的钢绞线斜拉索的计算结果进行对比分析,计算结果表明:由于CFRP索的弹性模量和单位长度重量低于传统的钢索,CFRP斜拉索的等效刚度系数小于钢拉索,索的竖向分力等效系数在工程应力范围内接近1,垂度效应明显小于钢拉索。
