【摘要】 斗式电磁振动给料器广泛应用于各自动化生产领域，对于不同形状、质量、材质、摩擦特性和输送要求的物料，给料器主要参数的选择和匹配也不一样，这一直是给料器生产、调试的重点和难点问题，也是给料器输送效率低、噪声大、给料速度不稳定的主要原因。因此有必要对给料器的结构进行分析，用理论方法建立其运动学和动力学模型，寻求各参数之间的最佳匹配。本文在分析国内外关于电磁振动给料器的研究成果后，分析给料器电磁力对振幅、振幅对物料运动方式和输送速度的影响。通过建立给料器的运动学模型，分析了振幅对物料输送方式的影响；推导了物料运动平均速度的计算公式；给出运动参数的选择方法。通过建立电磁振动给料器的动力学模型，给出最佳频率比和动力参数的选择方法。通过对给料器电磁力计算公式的推导，给出电磁参数的选择方法。最后用实验验证模型和参数选择方法的可行性。本文的重点是针对电磁振动给料器各种励磁方式下电磁力的计算方法，特别是详细分析了非谐波形式电磁力与触发角的关系。为设计给料器时分析和计算电磁力提供参考。更多还原

【Abstract】 An electromagnetic vibration feeder is widely used in the areas of automatedproduction. It is always the major problem that the choice and matching of the mainparameters were not the same for the supplies with different shapes, mass, materials,frictional characteristics and transport requirements, and it is the main causes of lowtransport efficiency, heavy noise and instable feeder speed. So it is necessary to analyze thefeeder structure and establish the kinematics model with a theoretical method to find theoptimum matching among parameters.The paper analyzed the effect of the electromagnetic force of a feeder on amplitudeand of the amplitude on the moving methods of the supplies and transport speed after thestudy of the research achievement on electromagnetic vibration feeder at home and abroad.By establishing the kinematics model, the effect of the amplitude on the transport methodsof the supplies was analyzed, the computational formula for the average moving speed ofthe supplies was deduced, the choosing method of the moving parameters was provided.By establishing the kinematics model, the choosing methods of the optimum frequencyratio and kinetic parameters were provided. By deducing the computational formula of thefeeder’s electromagnetic force, the choosing method of electromagnetic parameters wasprovided. Finally, the feasibility of the models and choosing methods was testedexperimentally.The focus in the paper is on the computational method of electromagnetic force undervarious exciting modes of electromagnetic vibration feeder, particularly, the detailedanalysis of the relationship between the electromagnetic force with anharmonic wave andfiring angle. This can be acted as a reference to the analysis and computation ofelectromagnetic force for designing a feeder.更多还原
