Abstract:
Objectives In order to meet the practical requirements for simulating ship motion in adverse sea conditions on land, the development of a high-speed heavy-load and large-travel lifting platform is necessary.
Methods Aiming at the characteristics of moving platforms such as heavy-load high-speed and variable parameters, the dynamic simulation analysis of a high-speed lifting platform with a weight-balanced structure and four-steel-cable synchronous servo drive is carried out on the basis of Adams simulation software. Based on the principle of the similarity of control characteristics, a 1∶14 reduced ratio high-speed lifting platform is developed.
Results Through the response characteristic testing of the platform, its advantages such as strong synchronization and highly accurate control system are verified. The moving platform can accurately simulate the heave motion of ships in adverse sea conditions.
Conclusions The high-speed lifting platform with a weight balance and four-steel-cable synchronous servo drive designed herein will fill in the blank for the large-scale heave motion simulation of ships and provide references for the R&D of similar motion simulators.
