specific Embodiment

[0044] Laser displacement sensor 12 adopts FT50 RLA-20 laser displacement sensor; acceleration sensor 15 adopts DH131 piezoelectric acceleration sensor.

[0045] Under normal experimental conditions, the laser displacement sensor 12 is fixed on the lower bracket of the clamping part of the excitation source, and the acceleration sensor 24 is fixed on a component close to the clamping part of the center of the vibration source by bolts. Each sensor measures in real time and transmits the data to the dynamic data acquisition system, and then the system is connected to the PC terminal through the network cable, and the vibration acceleration and vibration displacement can be tested and analyzed in the computer operating system. It can also complete the test and analysis of stress and strain by pasting metal strain gauges on the workpiece, and finally complete the real-time storage, real-time display and real-time analysis of the four elements of vibration. The specific data acquis...

Abstract

The invention discloses an adjustable clamp device for a beam member vibration aging platform. A suspension plate is horizontally arranged on the upper ends of a U-shaped support; the lower end of the suspension plate is connected with a support plate through a connecting rod; and a clamping fixture is arranged between the suspension plate and the support plate. The clamping fixture comprises a rotation disc. The bottom surface of the rotation disc is provided with slide grooves; each slide groove is internally provided with an adjusting screw rod; each adjusting screw rod is provided with a press plate; and the end of the adjusting screw rod is coaxially provided with an adjusting gear and an adjusting knob. The upper end of the rotation disc is provided with a center shaft. The center shaft is provided with an adjusting disc. A support spring is arranged between the adjusting disc and the rotation disc. The bottom surface of the adjusting disc is provided with a big gear ring. The upper end of the adjusting disc is provided with a nut ring. The center of the bottom surface of the adjusting disc is provided with an upper fixation gear ring; and the upper end surface of the rotation disc is provided with a lower fixation gear ring. The clamp device is high in adjustability, flexible to operate and wide in application range, has enough clamping force to ensure stability of the workpiece and can prevent member deformation.

Description

technical field [0001] The invention relates to the technical field of material detection equipment, in particular to an adjustable clamp device for a beam component vibration aging platform. Background technique [0002] Due to the quenching, casting, welding, forging, hot and cold straightening of aerospace aluminum alloy workpieces, a large amount of residual stress will be generated. The uneven distribution and high peak value of the residual stress are the main reasons for the deformation, warpage, cracking, stress corrosion, reduction of deformation resistance, fatigue limit reduction and fracture toughness reduction of the workpiece. At present, there are mainly three methods for eliminating and homogenizing the residual stress of workpieces: natural aging, thermal aging and vibration aging. Among them, vibration aging has attracted extensive attention because of its advantages of high efficiency, energy saving, and low cost. The fixture of the traditional beam membe...
