| Hydraulic disc brakes are very important marine winch assembly, its operation status is normal or not to directly affect the safety about the marine towing winch and its equipment. With the rapid development of modern high-tech, modern industrial processes are maturing, so machinery and equipment requirements are also increasing too. There are many problems about disc brakes such as target control fluctuations, response lag, lack of brake torque, brake disc pollution, etc. Therefore, the normal working operation about ocean winch caused a great impact. Conventional hydraulic disc brake system has not been able to meet application on it. Therefore, by optimizing the selection about the structure of marine winch on hydraulic disc brakes, calculating the parameters of its various components, then simulating and analyzing its four conditions by simulation software, combined with the marine winch hydraulic disc brake system to do comparison test analysis, we can verify the feasibility of the optimal design. Its main contents are as follows :There are the basic principle and design requirements on marine winch hydraulic disc brake system. According to the marine winch hydraulic disc brake system basic principle, marine winch brake having a brake torque reserve, Threshold braking deceleration, braking device safety margin, brake action sensitivity, classification braking system design requirements, to explore the marine winch structure style disc brake system and how it works.There is a mechanical disc brake system design and parameter calculation. By analyzing the working environment and conditions of use of marine winch disc brake system to address oil pollution brake disk, can easily replace the brake pads, brake discs and brake shoe clearance adjustment problems. By calculating the marine winch brake torque disc brake system, brake arm, disc springs, hydraulic cylinders, brake discs, etc., can determine the mechanical structure of marine winch disc brake system.There is a simulation about the disc brake systems for marine winches. Through marine winch disc brake system works analysis, can design the hydraulic system for the marine winch disc brakes. Disc brakes can be simplified a mechanical model of the hydraulic cylinder with spring. Based on the model, the disc brakes can be set up in AMESim simulation. Using the AMESim software can simulate the braking device in a variety of operating conditions. Get various conditions of hydraulic cylinder hydraulic brake positive pressure piston displacement curve, which has been well-established marine winch disc brake device Solidworks model into ADAMS simulation software to give its angular displacement with time and the angular velocity versus time curve, the analysis of its braking performance.Test marine winch hydraulic disc brakes Model. Through the establishment of marine winch hydraulic disc brakes experimental system, respectively hydraulic cylinder hydraulic pressure curve. Comparative analysis of hydraulic oil pressure curve curve and simulation of marine winch disc brake system experiment was obtained by. |
