摘　　要：以液压约束活塞发动机连杆为研究对象,采用现代优化设计方法与有限元相结合的技术,建立了连杆优化的力学模型。在保证结构强度、刚度和稳定性的条件下,进行了以连杆质量为目标函数的三维结构优化设计,结果使连杆质量更轻,结构更加紧凑。得到了一种综合考虑各种约束条件的连杆优化方法。As the research object with the connecting rod of hydraulic confined piston engine, the combination of modem optimize design methods and finite element technology is used and the mechanical model of optimize is set up. On the conditions of the structural strength, stiffness and stability, and quality as the objective function, three - dimensional structure optimize is carried out, so that the quality is more light and structure is more compact. A comprehensive consideration of various constraints of optimization method is gotined.
