The hybrid dynamics of multi-rigid-body and multi-flexible-body system becomes the mainstream of multi-body dynamics. Currently there lacks a compact approach to model the hybrid dynamics, especially ...
For the purpose to facilitate development of high-speed Spindle Units (SUs) running on rolling bearings, we have developed a beam element model, algorithms, and software for computer analysis of therm...
In the determination of the process accuracy on CNC lathe it is very important to know the thermal deformations. This article presents a new solution to obtain the thermal deformations at the principa...
对动力系统用两级先导式电磁阀进行了动力学分析。建立了基于电磁阀阀芯振动与流体流动相耦合的系统动力学模型。模型充分考虑了阀芯自激振动,阀内各腔以及阀前后管路内压力变化。分析了不同工作条件下阀芯的稳定性,研究了工作压力、工作流量对电磁阀动力学特性的影响。
The path followed by and the tension generated along a yarn under a false-twist process using an enlarged model unit of a doubly stacked multi-disk spindle are measured and analyzed on the basis of a...
The basic element of each multiple-spindle driller is its working unit also called drilling head. The use of multi-spindle drill heads enables simultaneous drilling of holes arranged in rows, which ...
This paper presents the results of observation and measurements of the wear of a spindle-neck coating made of the aluminium alloy AlCu4Mg1 of an anti-balloon crown of a PG-7A ring-spinning frame. Eva...
This study focuses on the effects of various spindle diameters and the spindle working period on the properties of 100% viscose MVS yarns. MVS yarn samples produced with four levels of spindle diamete...
In response to increases in cotton production costs, producers are seeking ways to reduce input expenses. Because brush strippers are less expensive to operate than spindle harvesters, research was pe...
By using a surface-modified templating method, Fe2O3@polypyrrole (PPy) core/shell spindles have been successfully prepared in this paper. The Fe2O3 particles with spindle morphology were initially fab...
