Abstract: A testing device for simulating frictional wear behaviors of threaded joints of a drill pipe under turbid seafloor environment, including a support, an oil cylinder, upper and lower specimens, a first motor, several second motors, stirring rods, a turbidity sensor, and a test tank. The oil cylinder and test tank are arranged on the support. A piston rod of the oil cylinder is connected to the first motor. A rotating-speed sensor is arranged on a bottom surface of the first motor, facing toward an output shaft of the first motor. The output shaft of the first motor is connected to an upper end of a torque limiter. A lower end of the upper specimen fits an upper end of the lower specimen under loading of a main shaft of the first motor. The stirring rods are provided at two sides of the test tank.
