摘　　要：为了改善电感测微仪测头的动态响应性能,找出测头的临界脱离频率,对影响测微仪测头临界脱离频率的因素进行了理论分析,并通过试验台对测头的刚度、质量及预压量等因素对其产生的影响进行了验证。试验结果表明:在对电感测微仪测头的设计中,合理增加刚度和预压量、减少活动部分的质量可以提高测头的动态响应性能。To improve dynamic response performance of inductive probe, the key problem is to find the probe＇ s critical frequency. The factors influencing the probe＇ s critical frequency was analyzed technically, and the complications effecting the probe such as its stiffness, mass and pre-compression capacity were verified through the test rig. The test results indicate that increasing reasonably the probe＇ s stiffness and pre - compression capacity and reducing the mass of movable part may enhance its dynamic response performance.
