摘要: 研究了采用浮力原理施力，用高灵敏度应变传感器测力的微负荷摩擦试验方法。测试结果表明，微负荷摩擦测试系统具有较高的分辨率和测试精度。Abstract: A method for testing and measuring of friction force at small applied load is introduced. The normal load is applied by means of buoyancy and the friction force is measured with a strain sensor. The construction and principle of the test rig are studied. It has been found that the test rig has high resolution and precision.
