摘要

本文研究了一种新设计的工业混合器的瞬态行为,该混合器包含了额外的工作头运动。与传统混合器不同,该混合器由弹性扭力杆组成,其纵轴与主传动轴垂直。使用弹性扭力杆悬挂工作头增加了额外的自由度,大大改善了流体或粉末的混合。根据角动量变化率定理,采用考虑驱动电动机动态特性的非线性微分方程系统对机电装置的运动进行了模拟。对不同工况下系统的瞬态过程进行了数值分析。最后,进行了约束多目标优化,以确定最优设计变量值,使混合器的力和功率特性最小。

Transient motion of an industrial mixer with elastically suspended work head
This paper investigates the transient behavior of a novel design of an industrial mixer incorporating additional work head movement. In contrast to conventional models, this mixer consists of an elastic torsion bar with its longitudinal axis oriented orthogonally to the main drive shaft axis. Using the elastic torsion bar to hang the workhead adds an additional degree of freedom, greatly improving the mixing of fluids or powders. The motion of the electro-mechanical device was simulated using a system of nonlinear differential equations that consider the dynamic characteristics of the driving electric motor, as derived from the theorem for the rate of change of angular momentum. A numerical analysis was carried out to study the transient processes in the system under different working conditions. Finally, a constrained multiobjective optimization was performed to identify the optimal design variable values that minimize the force and power characteristics of the mixer.

期刊介绍: Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
