AI Technical Summary
Existing technologies lack suitable testing equipment and methods to simulate the stress on large-diameter pins in engineering applications, making it impossible to accurately determine the pin's bearing capacity, reasonable embedment depth, and stress unevenness coefficient, resulting in inaccurate design parameters.
A method and apparatus for testing the stress of large-diameter pins were designed. Through tests with different burial depths at equal intervals and tests with non-uniformity coefficients, combined with displacement gauges and jacks, the load-displacement curves of the pins were recorded and analyzed to determine the bearing capacity, reasonable burial depth, and non-uniformity coefficient of the pins.
Accurate simulation of the stress mode of the pin was achieved, and the bearing capacity, non-uniformity coefficient and reasonable embedment depth of the pin were accurately determined, providing reliable parameter basis for the shear design of large-diameter pins.
