柴油机缸盖应力与缸内压力关系仿真研究
Simulation Study on the Relationship between Cylinder Head Stress and Cylinder Pressure
摘要: 利用柴油机缸盖的应变效应将缸盖结构件的内部变形转换为具体数值，通过给柴油机缸盖施加压力载荷，测量其动态状态的应变。本文论述了柴油机缸盖对于不同的缸内爆发压力，其应力分布情况，针对6135柴油机缸内爆发压力对柴油机缸盖不同位置应变仿真研究，得出最佳测试点。通过测量缸盖应力反演柴油机缸内爆发压力，及时发现柴油机单缸压力故障，从而避免更大事故发生。在一定程度上对各类柴油机单缸压力检测提供参考。
Abstract: Using the strain effect of the cylinder head, the internal deformation of the cylinder head structure is converted to the concrete value, and the strain of the dynamic state is measured by applying pressure load to the cylinder head of the diesel engine. Based on the simulation study of 6135 diesel engine cylinder pressure on cylinder head strain in different positions, this paper discusses the diesel engine cylinder head for different explosion pressures in cylinder and its stress distribution, and gets the best test point. By measuring the stress inversion of explosion pressure in cylinder diesel engine cylinder head, it discovers diesel engine cylinder pressure fault in time, to avoid more accidents. To some extent, it can provide reference for the single cylinder pressure test of all kinds of diesel engines.
