Abstract: The contrast experiments between ultrasonic vibration honing and ordinary honing are firstly taken. It shows that the removal rates and the working accuracy of ultrasonic honing are much better than that of the ordinary honing. Then the optimum experiments on technological parameters of ultrasonic vibration honing on engine cylinder is taken, which gained the proper technological parameters. The experimental results indicate that the gained parameter totally meets the actual need and reaches a new height in this field, which provides the reliable technological parameter for the ultrasonic vibration honing to process cylinder and has a broad application in prospect.

Abstract: This paper introduces the new technology of ultrasonic vibration honing, and analyzes the cutting principle of ultrasonic honing in terms of cutting motion, grain performance and cutting quantity. Then, the applied effect used in the cast-iron cylinder of DY90 is introduced. The principle and the structure of this device are discussed. This new technology can further be used in micro-car’s cylinder, can provides a high-productivity, high-quality for cast-iron cylinder.

Abstract: In the design of ultrasonic honing equipment, it is hard to accurately get the natural vibration frequency of the ultrasonic vibration with the regular computing technology, which takes great inconvenience during designing of the device and puts it into production. This paper studies the ultrasonic vibration honing vertical equipment of φ150mm that is designed by the North University of China and carried on the natural vibration frequency analysis and corresponded numerical simulation, which got excellent achievement. In the paper the mathematical model is set up, which uses the MARC software to accomplish the numerical simulation and corresponds the vibration modal of the tool head of the devise, this paper also carries on the dynamic response analysis and solves the related difficult problem successfully. In the end, the proof test is done to support the theory.
