摘　　要：刚度特性是弹性轴承的主要力学性能,在产品最终确定和批量生产之前,均需对设计出来的弹性轴承进行各项刚度特性试验,用来验证所设计生产出来的弹性轴承的各项参数与生产工艺是否达到产品的质量和性能所需要的标准。通过采用压扭一体试验机以及两端支撑结构实现了对中心弹性轴承扭转、弯曲、压缩和径向刚度特性的准确测量,试验方法可靠性高、试验结果准确性强,是确定设计制作出来的弹性轴承合格与否的重要判定依据,同时为产品的提升和改善提供发展的方向,是旋翼系统不断创新、改进的重要环节。Stiffness characteristics is the main mechanical property of elastic bearing,before the product is trial-produced,fixed,installed or put into production in batches,it is necessary to carry out various stiffness characteristics tests on the designed elastic bearing to check whether the design and production process of elastic bearing can meet the requirements of product performance and quality.By adopting pressure torsion testing machine and the two-terminal bracing structure complete the accurate measurement for torsion,bending,compression and radial stiffness characteristics of central elastic bearing,the test method is reliable,accurate and can as an important basis for elastic bearing's quality,at the same time,it can provide the direction of next improvement for product,it is an indispensable link in the course of the rotor development.
