Active wave compensation simulation experiment system platform

Abstract

The invention discloses an active wave compensation simulation experiment system platform, which is characterized in that a supplied ship deck and a supply ship deck are driven by using a six-degree-of-freedom platform to simulate up-and-down movements of sea waves, relative velocity and displacement signals of a crane relative to the supplied ship deck are detected by using a laser sensor, the signals are processed by a control system, the next control variable is worked out, the signals are transmitted to a driving system, the driving system drives a winding cylinder through a driving gear pair, the winding cylinder drives the crane to move through a rope, the relative velocity of the crane is enabled to be consistent with the target velocity, and a function of wave compensation is realized. The active wave compensation simulation experiment system platform can effectively simulate kinematic and dynamic characteristics of the crane in inter-ship supply operations and perform verification on actual effects of various different wave compensation control algorithms, thereby being capable of effectively promoting application and popularization of the wave compensation control algorithms in practical production operations, and having excellent practical values and promotion values.

Description

technical field [0001] The invention relates to the field of port machinery, in particular to an active wave compensation simulation experiment system platform. Background technique [0002] With the rapid development of the times and the globalization of the economy, port transportation has become more and more frequent and has become an indispensable link connecting the economies of various countries. However, there are also a series of problems in port transportation that need to be overcome. Among them, the marine crane is an important transportation tool for lifting and supplying materials between ships. The crane is fixed on the hull, and the hoist is connected to the hoist through a wire rope, and the lifting of the hoist is controlled by the forward and reverse rotation of the hoist. and drop, but the undulation of the sea during operation is likely to cause relative movement between the supply ship and the supplied ship. When the crane is replenishing materials at ...

[0005] The purpose of the present invention is to provide a convenient, economical, safe The active wave compensation simulation experiment system platform in a laboratory environment that is reliable, reliable and close to the actual working environment can effectively simulate the kinematics and dynamics characteristics of the crane's replenishment operation between ships, and easily replace the control algorithm. Verifying the actual effects of various existing and newly researched heave compensation control algorithms can effectively promote the application and popularization of heave compensation control algorithms in actual production operations, and can also indirectly overcome the problem of marine cranes. The frame has the disadvantages of huge collision loss due to heave caused by sea waves, high operating standby rate and low efficiency
