| 摘 要： | 基于模态参数的动态特性,针对某型柴油机振动噪声超标问题,利用有限元软件ABAQUS的模态分析功能对主要噪声源油底壳的自由模态进行计算,从固有频率方面着手优化其结构。优化后的其固有频率大幅提高,经整机振动噪声测试,减振降噪效果明显,解决了振动噪声超标问题。

| Abstract: | Base on the dynamic characteristics of modal parameter,About the problem that the vibration and noise outlawed in the vibration and noise test of diesel engine was analysised,The mode of oil sump which is main noise was calculated by using the modal analysis function of finite element software ABAQUS,The oil sump was optimized with the natural frequencies. The natural frequencies were improve significantly After structural optimization,The vibration and noise reduced sharply in the vibration and noise test ... |
