2、发动机设计课程设计是在我们学习了一些基础制图知识和汽 车以及发动机的整体知识框架后所给我们的一次很好的锻炼，众所周知现代汽车工业发展 越来越快，而作为汽车心脏的发动机自然也成为了发展的重中之重，发动机的结构和性能 对汽车起着决定性的影响，比如汽车的行使速度、加速性能、爬坡度、牵引力等等都取决 于发动机，因此来说设计发动机是汽车设计的重中之重，而发动机的设计又对我们的想象 能力，制图能力，分析计算能力，查阅各种工具书的能力无疑是一次很好的锻炼，因此,，保证咼质量的去完我们要充分利用这次课程设计的机会，认真对待，做好充分的准备 成，这也为以后学习打下了一个很好的基础。2结构参数计算2.1已知条件平

8、力传给 曲轴。连杆小头与活塞一起作往复运动，连杆大头与曲轴一起作旋转运动，连杆杆身作复 杂的平面摆动。连杆主要承受气体压力和往复惯性力所产生的交变载荷。由于受力比较复 杂并且需要实验来指导，因此设计时应综合考虑。6.1连杆主要尺寸的设计6.1.1连杆长度的确定1连杆长度由杆比A来说明，而A二丄，几值越大，连杆越短，则发动机的总高度越小。r参考杨连生版内燃机设计设计，A值范围为-。取A =0.3，3.23.8I =42mm 子 0.3=140mm6.1.2连杆小头尺寸的确定连杆小头位于活塞内腔，尺寸小、轴承比压高、温度较高。本次设计汽油机的连杆材料选取为45钢，密度P =7.85g/cm3.连杆

10、连杆轴承、主轴承负荷增大，磨损加剧，有时还 不得不为此而增加平衡重，给曲轴设计带来困难，因此在设计连杆大头时，应在保证强度和刚度的条件下，尺寸尽量小，重量尽量轻。连杆大头内径，参考杨连生版内燃机设计设计Do=0.55 0.65，取DD2 =0.58D =46mm连杆大头外径，参考杨连生版内燃机设计设计,D2/= 0.60 0.68，取 D 2 D=0.62D=50mmC/ D 2 =1.2 1.25,连杆螺栓孔间距离，参考杨连生版内燃机设计设计,C=1.2D 2 =62mm高度H3,参考杨连生版内燃机设计设计,H3 / D 2 =0.35 0.4，取H3=0.38D 2=20mm高度H4，参考

17、机设计以及大二和大三进行过的课程设计的基础上的一次专业课程 设计，我学到了许多大三、大四都没来得及好好学的关键内容，而且在实践中运用，更是 令我印象深刻，深切体会到课程设计并非以前所想像的那样纸上谈兵。所有理论、公式都 是为实践操作而诞生的。可以说是对我所学知识的一次很好的巩固和回忆，并且在设计过 程中，我还学会了查询各种工具书的方法，提高了想象能力，学会了怎样把学到的各门学科的知识融会贯通，并提高了作图的能力以及用Excel处理数据和绘制图形的技能，使我对发动机原理及内部结构有了更加深刻的认识。18参考文献1杨连生.内燃机设计.北京：中国农业机械出版社,1981.2陆际青.汽车发动机设计.北
