[Abstract]:The hydraulic disc brake device is a very important component in the offshore winch, and its normal operation directly affects the safety of the marine winch and its towing equipment. With the rapid development of modern high technology, the process of modern industry is becoming more and more perfect. There are many problems in the disc brake device, such as large fluctuation of target control, lag of response, insufficient braking torque, pollution of brake disc, etc., which have a great influence on the normal operation of offshore winch. The traditional hydraulic disc brake device can not meet the application in the ocean winch. Therefore, by optimizing the type selection of the structure of the hydraulic disc brake device of the offshore winch, and calculating the parameters of each component, the paper uses the simulation software to simulate and analyze its four working conditions. In order to verify the feasibility of the optimal design, a comparative analysis is made on the hydraulic disc brake system of the offshore winch. The main contents are as follows: (1) the basic principle and design requirements of hydraulic disc brake device of offshore winch. According to the basic principle of the hydraulic disc brake device of the offshore winch and the design requirements of the brake device of the offshore winch, such as the reserve of braking torque, the value of braking deceleration range, the safety reserve of braking device, the sensitivity of brake action, the step braking system, etc. This paper discusses the structural pattern and working principle of the disc brake device of the offshore winch. (2) the calculation and optimization of the parameters of the disc brake device of the offshore winch. Through the calculation of braking torque, disc spring, hydraulic cylinder and brake disc of the disc brake device of the offshore winch, the mathematical model of the disc brake device of the offshore winch is established, and the optimum parameter model is determined. (3) the simulation study on the disc brake system of the offshore winch is carried out. Based on the analysis of the working principle of the disc brake system of the offshore winch, the hydraulic system of the disc brake device of the offshore winch is designed, and the disc brake device is simplified into a mechanical model of the hydraulic cylinder with spring. According to this model, the simulation model of disc brake device in AMESim is established, and the brake device under various working conditions is simulated by using AMESim software. The variation curves of oil pressure, positive brake pressure and piston displacement in hydraulic cylinder under various working conditions are obtained. The established Solidworks model of the disc brake device of the offshore winch is imported into the ADAMS simulation software, and the curves of angular displacement and time, angular velocity and time are obtained. The braking performance is analyzed. (4) the test analysis of hydraulic disc brake model of offshore winch. The hydraulic pressure variation curves of the hydraulic cylinder were obtained by establishing the hydraulic disc brake system of the offshore winch. The oil pressure variation curve obtained from the experiment of ocean winch disc brake system and the oil pressure change curve obtained by simulation are compared and analyzed.
