基于ADAMS的某柴油机配气机构动力特性的研究

为研究16PA6STC型柴油机配气机构系统动态特性,首先介绍了该型柴油机配气机构的工作原理,并用ADAMS软件与PRO/Engineer软件建立了动力学模型,在此基础上对该机配气机构进行了运动仿真分析,得到了进、排气门等关键部件的位移、速度、加速度以及受力等运动学和力学参数。将仿真数据与理论数据对比,验证了动力学模型的准确性,进而分析了不同柴油机转速对气门速度的影响,为进一步有限元结构分析以及系统优化提供了基础。

Study of dynamic characteristic of diesel engine valve train based on ADAMS

In order to study the dynamic characteristic of 16 PA6STC diesel engine valve train,the working principle of the ongine valve train was introduce first in the paper,and then a dynamic model was built using ADAMS software and PRO/Engineer software. On this basis,the movement simulation analysis of the engine valve train was done,getting some characteristic parameters of inlet and exhaust valves,such as displacement,speed,acceleration,load,etc. By comparing the simulation data with the theory data to verify t...
