Method for testing equivalent friction coefficient of traction sheave matched with steel wire rope

The invention discloses a method for testing an equivalent friction coefficient of a traction wheel matched with a steel wire rope, which comprises the following steps of: arranging the traction wheel, a guide wheel, the steel wire rope, a first counterweight block and a second counterweight block, and then driving the traction wheel to carry out multiple groups of reciprocating rotary motion tests with the same operation cycle through a driving device; measuring the slip variation of the second counterweight block in the reciprocating rotation motion with the same operation cycle each time, and calculating the average slip variation of the second counterweight block in the reciprocating rotation motion test with the same operation cycle in each group; and comparing the obtained average slip variation of the second counterweight block, and if the average slip variation of the second counterweight block is suddenly changed, stopping the test and calculating the current equivalent friction coefficient f.
