On, front and back ends supporting block is respectively arranged at the front end and middle section of knife bar, is marked with damping oil between damping body and adjustment bar, is formed
One passive type vibration insulating system feeds back one group of control force after the vibration in knife bar front end and middle section is passed to vibration insulating system, control
Knife vibration of bar, achievees the purpose that vibration damping.
D, in damping shock absorber, due to being the long cone of both ends support, its vibration form is mainly that the radial direction of single order is flat
Dynamic and second order length direction is swung, and is just matched with the single order of cantilever beam pattern knife bar and second_mode；It is big by taper
It is small to can adjust its position of centre of gravity, it is combined with the adjustment of both ends elastomer rigidity size and damping oil, can preferably be fitted knife
The single order and second order formation frequency and the vibration shape of bar control the vibration of knife bar resonance zone, are decreased to it minimum.
E, cutter tip is set on the front supports of knife bar front end, and cutting force makes knife bar generate vibration, by built-in resistance
Buddhist nun's damper reduces to control；The vibration of its low order influences maximum to cutting, and single order vibration front end amplitude is maximum, with long cone
Damping body is as quality of assistance, and center of gravity Forward, bigger to the control force of front end, effectiveness in vibration suppression is more preferable.
Compared with prior art, the invention has the following beneficial effects:
(1) mass block inside damping shock absorber and its both ends elastomeric components form a passive type vibration insulating system, resistance
The support block assembly at Buddhist nun's damper both ends is respectively arranged on the front end and middle section of cutter bar body, and the vibration in knife bar front end and middle section is passed
One group of control force is fed back after passing passive type vibration insulating system, can control the vibration of cutter bar body, to achieve the purpose that vibration damping；
