The invention relates to a friction measurement device which comprises a disk drive system, a ball drive system, a displacement adjusting system, an angle adjusting system, a loading system, a lubricating system and a test system, wherein the disk drive system drives a disc to rotate through a disc shaft; the ball drive system drives a ball to rotate through a ball shaft; the displacement adjusting system is used for adjusting the relative position between the disc and the ball; the angle adjusting system is used for adjusting the angle between the disc shaft and the ball shaft; the loading system is used for providing a loading force for the disc and the ball; the lubricating system is used for providing lubricating oil for the disc and the ball; and the test system is used for measuring the friction force between the disc and the ball through a tension sensor. The friction measurement device not only can test the friction lubricating property under a high-speed medium-loading working condition but also has the characteristics of high measurement accuracy, good stability and the like.
