BR-LJD type bolt connection dynamic and static comprehensive experimental platform


This experimental platform is designed with a new concept, utilizing modern testing methods and computer technology to collect, process, measure, simulate, and compare the static and dynamic parameters of bolt connections. The experimental platform is equipped with a self-developed high-precision static and dynamic testing instrument, which can achieve manual drawing and computer drawing of the force deformation curve of bolt connections. Enable students to understand the basic methods of mechanical parameter electrical measurement and master the new experience brought by the effective combination of computer-aided testing curve drawing and computer simulation testing analysis.

Function and features:
1. Computer assisted testing and simulation of static and dynamic force deformation curves for bolt connections can automatically generate experimental reports simultaneously.
2. The experimental platform is equipped with two types of test bolts, solid and hollow, as well as two types of connected components, elastic and rigid. By changing the different stiffness combinations and stress amplitude ranges of the connected components and the connected components. The magnitude of the preload is used to verify the various measures to improve the strength of the bolt connection under variable stress.
3. Equipped with high-precision amplifiers, 24 bit A/D conversion, and 4-channel static and dynamic strain gauges with automatic zero calibration.
The manufacturing accuracy of the experimental platform is high, which ensures good repeatability of bolt connections in dynamic testing.
★ The device has added a remote communication protocol module, which can achieve:

Remote teaching function:
1) Real time teacher and student one-on-one remote teaching, remote communication function;
2) Manufacturers and equipment administrators provide real-time guidance on equipment operation and maintenance;

Laboratory management functions:
1) The equipment is equipped with a set of laboratory management system software and hardware, implementing a one person, one account mode for administrators. Through the mobile APP communication protocol, administrators with more than 10 people can manage the equipment at any distance, including recording (automatic start) and playback of the equipment operation process, as well as automatically starting the infrared alarm function when the equipment is turned off.

Teaching experiment projects and content:
This experimental platform can be used to connect two types of stiffness bolts and two types of stiffness connected components, equipped with elastic and rigid gaskets respectively, for a total of 8 sets of static and dynamic experiments.
1. Solid bolt+rigid connected part+rigid gasket
