WQ-JXLS bolted comprehensive experimental station of the test bed is the use of modern testing methods, the use of sensors and computer bolted static and dynamic parameters for the collection, processing, laboratory equipment simulation, testing and analysis to be completed by the bolt stress and deformation measurements data stability, repeatability, for mechanical design, mechanical design, innovative design courses open, comprehensive experiment is one of the important equipment mechanical design laboratory. Pilot projects: 1. Single bolt connection static and dynamic force experiments, and the coupling bolts to draw the hands of the static and dynamic deformation curve. 2. Understand a single bolt screwed tightly coupled to each part of the process of tightening the forces species. 3. When moving through the bolt axial load by changing the relative stiffness of the coupling bolts experiment to observe the changes in dynamic stress amplitude bolt to verify various measures to improve the strength of the bolt connection, and can print realistic and measured curves. Main technical characteristics: 1. Can achieve eight different relative stiffness of a single bolt tight coupling, and thus complete its static and dynamic experiments. 2. The software has bolted static and dynamic test and simulation functions. 3. Bench shape for the table plate + box floor structure, with adjustable anchor bolts and wheels for easy adjustment of the laboratory layout. The main technical parameters: ◎ three-phase AC motor power: N = 375W n = 910r/min; ◎ resistance strain gauge resistance values: R = 120Ω; ◎ sensitivity coefficient: K = 2.20; ◎ Dimensions: 600 × 355 × 1300mm;
