By the friction mechanical analysis and frictional damping analysis to overhead traveling crane heave compensation system simulation model, following knot is obtained
By:
As shown in Figure 1 it is drill bit curve of load when crown-block heave compensator passively compensates, is not considering hydraulic cylinder in figure
Frictional force exist to Bottom Hole Bit Weight In A influence of fluctuations under conditions of, the fluctuation amplitude of load at any time on drill bit in range, and
Smooth sinus fluctuation is presented in integrated curved；And there are frictional damping and cause compensating hydraulic cylinder with the presence of pressure drop in consideration hydraulic cylinder
When, crown-block heave compensator is larger to the decline of the compensation efficiency of drilling platforms heave movement, and shaft bottom drill bit load is at any time at this time
Between the wavy fluctuation of apparent approximate triangle is presented, the fluctuation amplitude of curve quickly changes in range.Overhead traveling crane is heaved and is mended
When repaying device and being in passive compensating coefficient, the influence that the frictional force generated in hydraulic cylinder fluctuates Bottom Hole Bit Weight In A is obvious, and curve
It changes with time and rapid fluctuations, while increases curve fluctuation amplitude by 2.03 times.

Under conditions of internal friction exists to Bottom Hole Bit Weight In A influence of fluctuations, the fluctuation amplitude of load at any time on drill bit is in 2.5kN model
In enclosing, smooth sinus fluctuation is also presented in integrated curved；And there are frictional damping and lead to compensating hydraulic cylinder in consideration hydraulic cylinder
In the presence of having pressure drop, crown-block heave compensator declines the compensation efficiency of drilling platforms heave movement, and shaft bottom is bored at this time
The wavy fluctuation of near sinusoidal is presented in head load at any time, but has oscillation on small scale phenomenon when curve fluctuates at peak value and make song
Line peak value further increases, and the fluctuation amplitude of curve changes within the scope of 4.7kN.It has the initiative for crown-block heave compensator
When compensating coefficient, the frictional force generated in hydraulic cylinder has an impact to Bottom Hole Bit Weight In A fluctuation, so that curve fluctuation amplitude increases by 88%,

Under the conditions of not considering frictional force, drill bit load amplitude fluctuation when in passive compensating coefficient is the 1.52 of Active Compensation state
Times.
By can be obtained after Simulation Example analysis, the compensation efficiency height of crown-block heave compensator depends on compensating brill
Pivot bur Bottom Hole Bit Weight In A fluctuation range, when the device during heaving movement compensation be in passive compensating coefficient and use
When dynamic balance oil cylinder, the frictional force generated in main compensation hydraulic cylinder has a significant impact to device entire compensation performance；When this
Device have the initiative during heaving movement compensation compensating coefficient when, the frictional force generated in compensating hydraulic cylinder is to device entirety
