A novel ultrasonic vibration approach is introduced into a chloroprene rubber/aluminum friction couple for improving the static friction properties betwesn rubber and metal.Compared to the test results without vibrations,the static friction force of a chloroprene rubber/aluminum couple decreases observably,leading to the ultimate displacement of rubber.The values of the static friction force and ultimate displacement can be ultimately reduced to 23.1％ and 50％ of those without ultrasonic vibrations,respectively.
