Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. Example embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The drawings are for illustration purposes only and are not drawn to scale.

[0024] Such as figure 1 , 2 As shown, a variable-angle ultrasonic impact test device includes a Langevin vibrator 11, an impact stage 12, a spring 7, a preload plate 8, bolts 9, and a support table 10, wherein the preload plate 8 can also be a flange.

[0025] Such as Figure 5 As shown, the support platform 10 is a hollow polyhedron structure, and the center of the bottom is provided with an arc-shaped through hole. The arch principle is used to increase the support rigidity of the support platform 10, while reducing the vibration of th...

Abstract

The invention provides a variable-angle ultrasonic impact test device and a variable-angle ultrasonic impact test method. The device comprises a supporting table, a pre-pressing plate, a Langevin vibrator and an impact carrying table. A threaded hole is formed in the middle of each surface of the upper end of the supporting table; the pre-pressing plate is incompletely fixed in the threaded hole through a bolt; the pre-pressing plate is used for supporting the Langevin vibrator, the Langevin vibrator achieves adjustment of multiple impact attack angles within the range of 0-180 degrees on thesupporting table, different friction materials are pasted to the impact area at the lower end of an amplitude-change pole and the upper surface of the impact carrying table respectively or simultaneously, and ultrasonic impact fatigue or abrasion tests of different types of friction materials are achieved.

Description

technical field [0001] The invention belongs to the field of ultrasonic vibration applications, and in particular relates to a variable-angle ultrasonic impact test device and method. Background technique [0002] In recent years, ultrasonic impact has played a very important role in scientific research and engineering applications such as material modification (such as reducing metal surface roughness and eliminating welding residual stress), ultrasonic catalysis, ultrasonic measurement and ultrasonic driving. However, under ultrasonic impact, the research on the fatigue and wear of the contact surface between the impact head and the impacted part needs to be further studied, and the related test methods and devices are even rarer. Chinese patent (CN1087115926A) discloses an ultrasonic impact device, the vibrator of the device is fixed, and ultrasonic impact with variable angle cannot be realized. Studies have shown that different angles of ultrasonic impact have different...
