Vibration Measurements of Clinched Joints

Abstract

As a result of the trend towards lightweight construction in sustainable manufacturing, there has been a significant increase in the use of clinched joints in engineering structures and components. Mechanical structures assembled by clinching are expected to possess a high damping capacity. The aim of this paper is to provide an experimental measurement technique for the investigation of the forced vibration behavior of clinched joints. The dynamic test software and the data acquisition hardware were used in the experimental measurement of the dynamic response of the clinched joints. The frequency response functions of the clinched joints of different clinching point number were measured and compared.

Connection of difficult-to-form sheets by clinching process: A review

“…The traditional clinching process only involves plastic deformation under quasi-static load at room temperatures, and the traditional constitutive model can predict the clinching progress accurately. However, with the development of new clinching processes, coupled fields, such as temperature field [117,118], vibration field [119] and electromagnetic field [48,49], are added, and the constitutive model is inadequate to capture the deformation behaviour of high temperature, high speed and frequency. Thus, researchers calibrated the constitutive equations of the material under the coupled fields [48,49,65,83,119], especially in the high-speed and high-frequency environment.…”
