大型设备路面运输中八自由度减振基座结构设计及动力学分析

设计了一种八自由度的减振基座机构,并用Creo5.0详细完成了该基座的装配过程。在该基座的结构中应用某有限的减振弹压杆并结合齿柱断齿吸能原理初始假设。根据达朗贝尔原理在常规大型设备运输的条件中简化模型并建立了运动学方程,建立了合适的振动模型的评价机制。通过MATLAB等软件对于滤波白噪声等方法建立的时域模型进行求解,为该基座在垂直振幅、基座上端盖俯仰角和倾斜角提供了准确的仿真分析。最后通过理论模型建立和仿真结果分析,证实了该基座在一定速度范围内减振的可靠性,为后续的应用于实际生产中提供理论支持并奠定了基础。

Structure design and dynamics analysis of eight freedom vibration damping pedestal in road transportation of large equipment

TThe design of a eight DOF vibration damping base mechanism, and use Creo2.0 with complete assembly process of the base; the structure of the base in the application of the damping spring rod a handicapping combined with tooth tooth fracture energy absorption principle. According to Darren Bell principle, the model is simplified in the condition of conventional large equipment transportation, and the kinematic equation is established, and the appropriate vibration model evaluation mechanism is established. By using MATLAB and other software, the time domain model established by filtering and white noise is solved. The accurate simulation analysis is provided for the vertical amplitude, the elevation angle and the inclination angle of the upper end of the base. Finally, through theoretical model building and simulation analysis, the reliability of the base is verified in a certain speed range, which provides theoretical support for the subsequent application in practical production and lays a foundation.
