摘要:新型二冲程微型摆式内燃机中心摆的振动会给其运行带来一定的危害。本文基于动力学理论和振动理论,采用虚拟样机技术,应用ADAMS软件建立中心摆模型并研究其振动特性。首先利用MATLAB软件计算出各工作阶段的压力随时间的变化,把计算出的参数赋予模型,利用Joints和Forces等工具约束三维模型,最后对其中心摆进行振动仿真分析,并绘制频率响应曲线,以验证其响应是否在所要求的范围之内。

Abstract: Vibration of the novel two-stroke
micro free swing piston engine's center swing is harmful to running of
internal-combustion engine.Based on dynamic and vibration theory,according to
the virtual prototyping technology,using ADAMS software to built the model of
engine's center swing and analysis it's speciality of vibration.First,using
MATLAB software to work out the press change at every working phase,endow the
parameters to the model,using "Joints" and "Force" to
restrict 3D model.at last,simulated and analyzed the swing,Then protracted the
curve of frequency response,validate weather the respond is normal.
Keywords: Micro Free Swing Piston
