【摘要】 随着经济的快速发展,能源危机和环境污染越来越成为成为全球所面临的共同难题,能源短缺将成为制约现代经济和社会发展的主要因素。开发新型能源已迫在眉睫,全世界各国都已经将发展可再生能源作为重要的工作来抓。与传统能源石油、煤炭、天然气相比,生物质能具有可以再生、开发经济、使用无公害、便于储存运输、燃烧性能好、热效率高等诸多优点,因此作为新型的可再生能源,其开发前景十分广阔。本文以TYK-1000A及JYW2-75生物质压块机为基础,以提高产量、节约能耗为出发点,进行JYL4-75生物质压块机的研制,研究的主要内容及得出的结论如下:(1)对影响生物质压缩成型的因素进行研究并通过Pro/E建立生物质燃料压块机的三维模型。(2)通过mech/pro将Pro/E中的实体模型导入ADAMS,利用函数拟合其实际工作时的载荷曲线,对模型进行仿真分析,得出各个零部件的受力、转矩及功率曲线,为下一步的校核及电机的选择提供依据。(3)利用ANSYS软件对关键零部件按进行有限元分析,了解各个部分的强度、刚度、稳定性特点。经过验证,证明相应的零部件满足实际工作载荷的要求。(4)应用ADAMS与ANSYS的联合仿真,建立曲轴、箱体的柔性体模型,成功解决了ADAMS中由于过约束所导致的零部件受力情况与实际不符的问题,得到了过约束处更为精确的受力情况,并将刚性体仿真与柔性体仿真的结果进行比较,可以看出,用柔性体仿真更为接近实际零部件在工作中的受力情况。本文对JYL4-75生物质燃料压块机的研制,具有实际的应用价值,对活塞冲压式压块机的进一步发展有指导意义。更多还原

【Abstract】 With the rapid development of economy,the energy crisis and environmental pollution has become a global problem, Energy shortage will become the main factor on confining modern economic and social development. It is urgent to develop new energy.And it regards a main job as to develop new energy.Compared with traditional energy of coal,petroleum and natural gas,biomass energy has many advantages,such as it can be recyled and easy to develop,clean and smokeless ,easy to transport and store,high burning quality and high calorific value.As a new energy, the development prospect of biomass energy is very broad.This design is based on TYK-1000A and JYW2-75 biomass briquetting machine,with the purpose of increasing the output and saving energy,the main research content and conclusion as follows:(1)The factors affecting its molding are studied and the 3D model of JYL4-75 biomass briquetting machine is built in Pro/Engineer.(2)The 3D solid model is put into the ADAMS by mech/pro, the load curve is fitted in ADAMS with the function in it, the model system is simulated and the stress of every part is gotten. The main purpose of the simulation is to provide the basis for the latter check .(3)The finite element analysis of some important parts are carried out with the large scaled finite element software ANSYS,so we can have a clear understanding of their strength,static stiffness and stability.After testing,it proves that these parts can meet the loads in the real work.(4)The flexible models of crankshaft and box are built by using the co-simulation with ADAMS and ANSYS ,the co-simulation can successfully solve the problem about redundant constraint in ADAMS,and then we know the more accurate stress near the redundant constraints.Compare the two results,we can find that the flexible model simulation result is more close to actual situation.This design about JYL4-75 biomass briquetting machine has an applied value and instructive meanings in the development of biomass briquetting machine.更多还原
