| 摘 要： | 在自行研制的钢丝绳隔震器静力测试台上对YGG系列鼓形钢丝绳隔震器分别进行轴向和侧向承载力试验,根据试验结果拟合隔震器的轴向静刚度、无轴向力作用的侧向静刚度、恒定轴向力作用的侧向静刚度计算公式;隔震器的侧向刚度与轴向受力状况密切相关,初始加载侧向刚度随轴向力的增加而增大,后期加载侧向刚度随轴向力的增加而降低。不同轴向力作用下的侧向加载曲线相互交叉,交叉点位于侧向容许动位移量的2/3附近;研究表明该系列隔震器的轴向刚度呈软化型,初始轴向刚度较大,可满足平时使用要求,刚度软化系数为0.34～0.43,大小适中,确保战时爆炸荷载作用下,隔震系统稳定可靠工作,且具有较高的隔震率。

| Abstract: | The axial and lateral bearing capacity tests for drum-shaped steel wire rope shock isolators of YGG series have been carried out on a static test and measurement bed.Based on the experimental results,calculation formulae for axial static rigidity and lateral static rigidity of isolators subjected to constant axial forces or without axial forces have been fitted.The lateral rigidity of the isolator is closely related to the axial force on it.The initial loaded lateral rigidity increases with the axial force,... |
