利用热-机耦合计算分析短冷却水套在非道路用柴油机上的应用

Application Analysis of Short Coolant Jacket in Non-road Diesel Engine Using Thermo-Mechanical Coupling Method

应用短冷却水套,既能有效地冷却热负荷高的机体中上部,又能减小缸孔的不合理变形,但是缩短水套势必会对机体刚度造成影响。以某款发动机为例,利用模拟技术,分析短水套对非道路发动机机体刚度的影响,推动短水套在非道路发动机上的应用。

The short coolant jacket is widely used in vehicle engines,which can not only effectively cool the upper cylinder block with high heat load,but also cool the cylinder to reduce the unreasonable deformations of cylinder bore.Based on CFD(Computational Fluid Dynamics) and test, the feasibility of the application of short coolant jacket in non-road moving machinery engine is verified.
