PAGE l 摘 要 为了更好的解决发动机曲轴扭震等问题，本设计以上柴6CL320-2的相关数据作为参照，对235kW直列六缸柴油机飞轮进行了惯量计算、结构设计、强度校核、离合器匹配，并对曲轴飞轮 组进行了有关运动学和动力学的理论分析与计算机仿真分析。 飞轮是一个转动惯量很大的圆盘，其主要功用是将在作功行程中传输给曲轴的功的一部分储存起来，用以在其他行程中克服阻力，带动曲轴连杆机构越过上、下止点，保证曲轴的旋转角速度输出转矩尽可能均匀，并使发动机有可能克服短时间的超过载；此外，在结构上飞轮又往往用作汽车传动系统中的摩擦离合器的驱动件。 关键词：飞轮 惯量计算 结构设计 离合器 运动仿真  Abstract In order to better solve the engine crankshaft earthquake such issues, the design CL320-2 6 above wood of related data as a reference, to 235 kw in-line six diesel engine flywheel the inertia computation, structure design, intensity, clutch matching, and of crankshaft fly wheel about kinematics and dynamics theory analysis and computer simulation analysis. The flywheel is a rotating inertia big disc, its main function is to do work in transmission of the trip to the crankshaft part of the power stored up, in other tour to overcome resistance, drive the crankshaft linkage mechanism, the check point across, guarantee of the crankshaft angular velocity output torque evenly as much as possible, and make the engine may overcome more than in the short time; In addition, on the structure of the flywheel and often used in automobile transmission system of friction clutch of driving part. Key words: The flywheel; Inertia computation; Structure design; Clutch; Motion simulation 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc311894576 摘要 PAGEREF _Toc311894576 \h I HYPERLINK \l _Toc311894577 Abstract PAGEREF _Toc311894577 \h II HYPERLINK \l _Toc311894579 第1章 绪论 PAGEREF _Toc311894579 \h 1 HYPERLINK \l _Toc311894580 1.1 选题目的、意义 PAGEREF _Toc311894580 \h 1 HYPERLINK \l _Toc311894581 1.2 发动机飞轮国内外研究现状 PAGEREF _Toc311894581 \h 2 HYPERLINK \l _Toc311894582 1.3 曲轴系统的扭转振动 PAGEREF _Toc311894582 \h 3 HYPERLINK \l _Toc311894583 1.3.1 扭转振动的基本概念 PAGEREF _Toc311894583 \h 3 HYPERLINK \l _Toc311894584 1.3.2 扭转震动的消减措施 PAGEREF _Toc311894584 \h 4 HYPERLINK \l _Toc311894585 1.4 汽车离合器结构的发展 PAGEREF _Toc311894585 \h 5 HYPERLINK \l _Toc311894586 1.5 飞轮设计方法 PAGEREF _Toc31189
