摘要
为解决如何真实模拟内燃机振动噪声激励载荷的关键技术问题,本文基于多体系统动力学方法,实现了对某型号柴油机曲柄连杆机构的动力学仿真分析,得到了相关载荷参数,为后续内燃机整机噪声分析和预测,提供更为准确的边界条件。
To investigate the dynamic excitations of engine,which are the sources of the vibration and noise,the dynamic simulation of the crank-connecting rod mechanism in certain diesel engine was carried out based on the multi-body system dynamics,and the relational dynamic characteristics were obtained.The simulation results are given as a more accurate boundary condition to analyze and predict the noise characteristics of the diesel engine in the future.
