摘要:
某新型高速变轨距动车组变轨机构中车轮、滑动套和车轴存在多层圆筒配合,为深入了解配合量对滑动套接触压力以及结构应力的影响,分别采用弹性力学和有限元分析的方法对其进行求解,并分析了不同配合量对接触压力和结构应力的影响。结果表明:除接触边缘区域,车轮- 滑动套接触压力与配合面过盈量成正线性关系;滑动套- 车轴间隙量对滑动套内孔面结构应力影响显著,其实际间隙值由于车轮- 滑动套过盈配合的压缩作用而小于设计值,所以设计间隙量时建议考虑车轮- 滑动套过盈配合的压缩作用。
Abstract:
sleeve and axle multi-layer cylinder fit is applied in gauge change mechanism of a new type of high-speed gauge-changeable EMUs. In order to research deeply on the influence of fit value on contact pressure and structural stress, methods of elastic mechanics and finite element analysis were applied respectively, and the effect of several different fit value were analyzed. Results showed that: apart from the edge of contact region, the contact pressure between wheel and sleeve is positive linear to the interference fit value; Clearance fit value of sleeve and axle has significant effect on the inner surface of sliding sleeve, and the real clearance value is reduced by the compression effect of wheel and sleeve interference fit; it is suggested to take the compression effect into consideration when design the clearance fit value of wheel and sleeve.
