为了解决机械式动筛跳汰机大型化过程中出现的振动强度大、连接部件寿命短、噪声大等问题,需要对其筛体驱动机构进行动力学研究。提出一种解析法与数值积分相结合的分析方法用于机械式动筛跳汰机的筛体驱动机构的运动学及动力学特性分析。分析过程中把驱动电机的瞬时特性计算与动力学计算相耦合。这样对于设备从启动到平稳运行的整个过程的动力学特性都可以做定量研究,使计算结果能够更加准确地反映出设备的实际运行状态。此分析方法既适合产品的初期设计又适合最终设计的校核,能够满足产品设计过程中的计算需求。
In order to solve the problems of large vibration intensity, short connection life and high noise in the process of large-scale mechanical moving jigger jigger, it is necessary to study the dynamics of its screen body driving mechanism. A new analytic method combined with numerical integration is proposed to analyze the kinematics and dynamics of sieve body driving mechanism of mechanical moving sieve jig. During the analysis, the instantaneous characteristic calculation of the driving motor is coupled with the dynamic calculation. In this way, the dynamic characteristics of the whole process from start-up to smooth running of the equipment can be quantitatively studied, so that the calculation result can more accurately reflect the actual running status of the equipment. This method is not only suitable for the initial design of the product but also for the final design of the check, to meet the computing needs of the product design process.
