摘要
利用动态优化设计方法对振动机械进行设计研究。基于拉格朗日法建立振动筛系统动力学模型,分析出了该系统的固有频率、主振型及系统的响应。利用Pro/E建立三维模型以及与AutoCAD相互结合的计算法,计算出了振动筛系统的质量、转动惯量、筛体的质心及弹簧到质心的水平和垂直距离,基于动态特性理论和计算机软件编程求出了系统的固有频率、主振型和系统的响应。根据计算结果,提出合理的设计方案。
Utilizing dynamic optimization design is carried out upon vibration machinery. Based on lagrange dynamics model of vibration machinery system is established. Natural frequency, vibration model and systemic response are worked out. Utilizing Pro/E 3D model is established. Combining Pro/E with AutoCAD, mass, moment of inertia, center of mass and upright distance from spring to center of mass for vibration screen are figured out. Based on theory of dynamic characteristic and programme for computer software, Natural frequency, vibration model and systemic response are figured out. Based on result, proper design scheme is put forward.
