摘要: |
内胀式液压缸性能试验存在锁紧力不合格的问题,通过改进锁紧套与缸筒选配方法,以及对锁紧套与缸筒间力学分析计算出过盈量,试验找出过盈量与缸筒圆柱度间的优化组合,确定最佳过盈量。优化后油缸试验的合格率提高约30%,效果明显。 |

Abstract: |
The locking force is unqualified in the performance test of internal expansion hydraulic cylinder. In the paper, the selection method of locking sleeve and cylinder barrel is improved. Through the mechanical analysis of the locking sleeve and the cylinder, the interference is calculated. The optimal combination of interference and roundness is found out. After the optimization, the qualified rate of oil cylinder test is increased by about 30%, and the effect is obvious. |
