Design and verification of self-adaptive control towing apparatus for ship model test

According to International Towing Tank Conference (ITTC) corresponding guidelines and rules, ship model test is vital for the determination on overall performance of the ship. In order to study ship speed performance, it is necessary to accurately determine its resistance in model scale. And during the test, an appropriate towing installation is very important because of its effecting on the heave and longitudinal angle of ship mode, which is the main factor of the resistance. Combined with the latest test equipment and control technologies, a self-adaptive control towing device design, resistance and posture measurement and control principle were studied, a towing system suitable for high-speed boat resistance test was developed, and the advantages of the system were analyzed. Based on this, and a standard planning craft model test is applied, which can verify the validity of installation.
