In this paper, load characteristics of the pill tucking simulation testing system have been studied, the program of the force loading maintainer has been explored, load transfer model has been built, the factors which influence the change of load force has been analyzed, and the design parameters of the force loading maintainer has been optimized.

The pressure mechanism of Direct Drive Wool Shearer and the influence of the length of it抯 pressure bar on the pressure are analyzed and studied in this article.

Analysis of working status of pressurization mechanism for coring tool in unconsolidated formation;

This paper makes a analysis of E7/4 combers on tongs plate's displacement, velocity, acceleration, the setting of carding and pressurization mechanism,and on the basis of above, it studies the movable characteristic of tongs plate mechanism of E7/4 combers and the effect on output ,quality by combers.

This paper figures the tongs plate pressurization mechanism and pressurization process of A201 series combs, It calculates pressurization spring camber, spring pressurization coefficient of drag, pressure transfer coefficient.

Through analyzing on load mechanism of dynamic and externally pressurized air bearing test stand,mechanical model is established and error function is constructed.

This paper carries out theoretical analysis of load mechanism of quartz resonant force sensor, and gives mathematical models of lode mechanism formed by flexible hinge.
