基于BRICKS的车用柴油机曲轴扭振与减振分析

Analysis of Crankshaft Torsional Vibration for a Vehicle Diesel Engine based on BRICKS Code

介绍AVL公司开发的发动机模拟软件BRICKS的功能和特点,针对某车用柴油机飞轮螺栓断裂问题,利用该软件对轴系进行了扭振与减振分析,并提出相应地改进措施,取得了预期的效果。

This paper introduced functions and characteristics of BRICKS code developed by AVL. Torsional vibration of crankshaft system of a vehicle diesel engine is analyzed by BRICKS code to find out the cause of a flywheel bolts broken.At last an improvement approach is proposed and implemented. The result is satisfactory.
