Thermo-elastic Contact Analysis of the Composite Piston in Highly-Uprated Locomotive Diesel Engines;
高强化机车柴油机组合活塞热弹性接触分析
In this paper,to study the composite piston with the steel crown and the nodular cast iron skirt of 16V 280ZJA diesel engine,four-body contact model of steel-crown-the nodular cast-iron skirt-piston pin-connecting bolt was constructed.
以 16V 2 80ZJA型柴油机钢顶球铁裙组合活塞为对象 ,建立了活塞钢顶 -球铁裙 -连接螺钉 -活塞销四体接触计算模型 。
Its reliability and service life are directly related to the locomotive diesel engine's efficiency, reliability and life expectancy, so that improving reliability of composite piston is a key factor for improving reliability of locomotive diesel engine.
组合活塞仿真分析与试验协同验证研究 针对铁路机车提速、重载后，机车柴油机钢头铝裙活塞出现的批量的活塞裙裂损事故，进行。
280 combined pistons had well been used on diesel engines of DongFeng series locomotives for a long time.
280组合活塞在东风系列机车中使用一直较为正常,但在2001年铁路大提速后,该活塞相继出现在中修区内的活塞铝裙裂损而导致的事故。

"After the piston-and-connecting-rod assemblies have been removed from the engine and the pistons and rods separated, the rings should be removed from the piston.."
先将活塞及连杆组件从发动机上拆下再把活塞与连杆分开之后,即可将活塞环从活塞上取下。

Install rings and confirm ring side clearance:
安装活塞环，并确认活塞环侧间隙：
The grooves into which they fit are called ring grooves.
安装活塞环的凹槽称为活塞环槽。
Most pistons have three ring grooves at the top.
大多数活塞的顶部有3个活塞环槽。
piston ring back clearance
(指与活塞底之间) 活塞环内表面间隙
"Thus, piston rings must be used to provide the necessary seal. The rings are installed in grooves in the piston. Actually, there are two types of rings, compression rings and oil-control rings."
所以活塞环就用来提供必要的密封。活塞环装在活塞的凹槽中。事实上有两种活塞环,气环和油环。
