摘　　要：提出并设计了新型钢丝绳隔振器及其弹性元件钢丝绳绳圈,为了探索隔振器刚度与隔振器结构参数之间的关系,对钢丝绳绳圈进行了研究。分析了钢丝绳绳圈的成形原理,采用空间坐标轴变换方法建立了7×7不锈钢钢丝绳绳圈钢丝中心曲线数学模型。根据建立的空间曲线数学模型和确定的结构参数,使用MATLAB软件绘制了钢丝绳绳圈钢丝中心曲线,并利用参数化建模软件Pro/E完成了钢丝绳绳圈的三维实体建模。通过研究得到了钢丝绳绳圈的空间曲线模型,发现了芯绳中心线上任意一点被其法平面所截截面不是一般研究文献中所假设的圆形或者椭圆,而是不规则截面,研究结果为进一步研究钢丝绳隔振器的动静态特性以及其结构参数对上述特性的影响打下了重要基础。The new structure steel wire isolator and the steel wire spring which is the basic elastic element of the steel wire vibration isolator are proposed and designed,the steel wire spring is studied in order to explore the deep relationship of the isolator’s stiffness resulted from the structure parameters.The forming principle of the steel wire spring is analyzed,the mathematical curve model of center wire of the steel wire spring which is in the structure form of 7 ＆#215;7 is established with space coordinate transformation method. With the curve model and the structure parameters,the mathematical curve model of center wire of the steel wire spring is plotted with MATLAB,and the three dimensional solid model is got with Pro/E.With the study above,it’s found that the section view which is got by cutting the steel wire spring with the normal plane established from any point on the three dimensional curve model is not circle or ellipse which are widely used in the analysis of steel wire,the section shape is abnormal.The study offers an important theoretical basis for the deeper study of static and dynamic characteristics of steel wire vibration isolator and＆amp;nbsp;the structure parameters’effect on the characteristics above.
