The paper presents the method of calculating the basic parameters of the hydromechanical element of the vibration of the oscillation, which allows realizing the rational law of changes in the Force Opru Gaser and time of growth of efforts in freight ropes, depending on the weight of the cargo.
A rational regression characteristic of the damping element of the gaser was realized by summing up the area of the cross sections of throttle holes. For this was found the strength of local resistance of these holes. Dependences of damping coefficient on the angle of rotation of the movable element of the piston in relation to the fixed one (angle of overlap of inductors) with diameter of throttle openings were analytically derived.
To implement the law of the resistance force change the authors a curved guide groove, made on the working surface of the hydraulic cylinder, the length of which corresponds to the stroke of the rod. Groove profile provides the necessary level of resistance of the damper element, depending on the progressive movement of the rod with a piston, which depends on the weight of the cargo. So at each point of the move the rod with a piston groove should set the value of the resistance that corresponds to the given law.
In accordance with this, as well as taking into account the rational selected parameters, a curved guide groove profile was built using a graphical and analytical method. So the dependence of the resistance coefficient of the damper element on the corner of the overlap of the throttle holes and distances passed by the rod depending on the weight of the cargo was analytically substantiated. Then we moved the projection of the overlapping corner ф to the projection of distances passed by Rod. As a result of the intersection of projection lines, points that define the curvature guide groove were obtained. The resulting curve is described by the mathematical dependence method of the least squares.
