A special pressure head for a spoke noise reduction plate according to claim 3, wherein contact surfaces of the floating seat (3) and the roller support (8) are respectively provided with mutually-matched triangular grooves which are divergent with the axis of the hinge shaft (10) as the center, the hinge shaft (10) penetrates through the floating seat (3) and the roller support (8), and the end part of the hinge shaft (10) is provided with a fastening nut (21).
5. A contact force calibration method suitable for the special pressure head of the spoke noise reduction plate according to any one of claims 1 to 4, mainly comprising the following steps:
s1, communicating a measuring element (7) with a containing cavity (2.1);
s2, placing a dynamometer (20) at a workpiece position, vertically feeding downwards through a ram (1) of the machine tool, enabling the rolling wheel (9) to be in contact with the dynamometer (20), and keeping a certain contact acting force;
s3, reading the contact acting force value F N And the pressure value P measured by the measuring element (7) N And calculate the calibration coefficient K N ：
S4, repeating the step S3, and measuring the calibration coefficient K for a plurality of times under different contact acting force conditions N And calculate and obtain the average calibration coefficient K 0 ：
S5, during rolling operation, calculating the actual contact acting force F of the rolling operation through the real-time pressure value actually measured by the measuring element (7):
F＝P N *K 0 ；
wherein P is N -real-time pressure values actually measured by the measuring element (7).
