In order to reduce the influence of the bench extraction equipment from the working deep-water exploration ship when it has swing or heave movement by wind and waves, according to the work condition and the structural parameters of 3000m deep-water exploration ship, Pump-controlled type and valve-controlled type hydraulic transmission system for waves compensation of deep-water exploration ship bench extraction equipment was researched through analysing and calculating. Wire rope which drags the bench is maintained appropriate tensioning status using this wave compensation system, when bench downs to the bottom of the sea. This system can bind and release wire rope to compensate for heave motion automatically, in order to keep the stability and security of the deep-water exploration ship before bench loading the bottom. Dynamic performance of wave compensation system is improved through controlling supplementation pressure and the accumulator parameters precisely.

This article through strong triangle structure of the shovel kinematics and mechanics model for the analysis of the kinematics and mechanics performance, and give strong triangle institutions mining envelope diagram, compared to the classic 10 rod 3 degrees of freedom of digging mechanism, proved what advantages the "strong triangle" has. Due to the strong triangle and the classic 10 lever 3 degrees of freedom in the difference on the structure, strong triangle institutions in the bucket special relative to the classic agency has the advantages of stability. Through research study "strong triangle" structure of the excavator, based on the kinematics and dynamics modeling method of parameter passing thought.
