Turbine rubber fender vulcanization process analysis

Rubber fenders are a kind of cushioning device used on ships or ships. Their inertia, energy absorption, long life, easy maintenance and standardized consumption are the driving energy of the vessel when it is parked or moored. Vessels, strengths, and use in Oman, Europe, and Northwest Asia are extremely broad. Keep the ship from maintenance. Compared with other material fenders, rubber fenders are in the development of the ancient shipping industry, light industry and station bows. The imagination, induction, construction and application of rubber fenders are receiving more and more attention.

Vulcanization is the beginning of the process of fender construction. The fender vulcanization process summarizes the final shape and rationality of the goods. Therefore, the research on the vulcanization process of the fender is extremely important. Two methods can be used to evaluate the vulcanization characteristics and frequency of the fender: one is the measurement process at the outer point of the fender by measuring the rubber fender type of the tugboat to be studied by the thermocouple 500 mm × 250 , using reasonable Power mm × 20 000 mm (outer diameter × inner diameter × length and length), the learning mold converts each point measurement into vulcanization level, which must be vulcanized in the inner, A, R and h are identified as 500 mm, 30 mm, 60 mm, the remaining time.

The changes in prescription imaging and the measurement of vulcanization media will be used in the trawling and pushing wheels of the various ethnic ports. Before being vulcanized, it is responding to the protection , and then it is reflected in the final cross-linking density and machine function of the rubber. On the inboard forming machine, the camera is ordered according to the consumption work point, and the camera must be cut to the ruler. After each test, the rubber fender must be cut. Flying to find the thermocouple inch, each forming a camera with a thickness of 50 mm and molding to the position of the beginning of the request , this trial and error method is profitable and long. Another method, the scale must be pressed once with a pickled dry water cloth, and standing 15~20 is a numerical skill based on computer simulation, directly looking out the fender min, retreating the dry water cloth, using gasoline to clear The peripheral camera, after monotony, measures and vulcanizes every half of the outside. Due to its structure and vulcanization, the nylon fabric was started to a thickness of 0.4 mm. Following the simplicity of the process, the Infinite Element Method (FEM) has been changed to study the semi-waste of the rubber fender to be hoisted into the fender vulcanizer. , an ineffective machine for fastening vulcanized products. As early as 1991, Toth et al. [1] used ABAQUS hardware in conjunction with its user sub-order HETVAL to construct a wheel preheating vulcanization meshing mold, modelling the vulcanization process of the belt and studying the initial measurement of the vulcanization response. In the same year, Marzocca used a one-dimensional FE mold to mimic the vulcanization process of a rubber fender cylinder. At first, Han et al. used their own developed hardware to stop the simulation and optimization of the wheel vulcanization process. Greenwell et al. studied the rubber vulcanization process, built a set of two-dimensional axis symmetry model with vulcanized wheel with VSTA hardware, studied the three-dimensional FE skill of vulcanization process, and established a three-dimensional infinite element model for simulating rubber vulcanization; using ABAQUS hardware In conjunction with the UMATTH user subsequence, a number of key results of the rubber vulcanization process were studied, such as the conductivity and specific heat capacity combined with the measurement and the degree of vulcanization, and a more accurate vulcanization kinetics model was constructed; the flow and irradiation borders were withdrawn during the icing phase. , began to directly test the simulation results through experiments. Therefore, WANG and others are also doing a lot of research missions in rubber vulcanization.

Shi Bin et al. completed the test of the belt vulcanization process and suspended the optimization of the imagination, and aimed at the thermal properties of the rubber vulcanization process, the preheating characteristics of the rubber cord, and the results of the dynamic characteristics, and identified the multidimensional thermal parameter model. The hybrid theorem model and the hybrid dynamic model are used to construct the vulcanization-preheating meshing mold. The ABAQUS hardware is combined with its user sub-order UMATHT to solve the induction. However, due to the shortcomings of thermophysical parameters and kinetic changes in the vulcanization process of rubber, a small amount of data accumulation and experience summary is still required, and there are few relevant briefings on the research of related fender vulcanization processes. To this end, the author of the white paper uses a tug rubber fender as a research object. First, by testing the thermal property parameters and rheological curves of the rubber fender material, the appropriate thermophysical parameter mold and dynamic mold must be appropriate; The side vulcanization process environment, the construction of the fender vulcanization? preheating meshing model, the suspension of simulation induction; began, the study of the climate environment, steam measurement on the fender vulcanization characteristics of the response. The study is very thoughtful about the rubber vulcanization practice block and the fender vulcanization process.
