根据导致误差的原因可以将误差分成有很多类别,如几何误差、运动误差、热误差、载荷误差、算法误差,等等,控制零件和零部件组装的几何精度、合理设计运动机构、优化结构件设计、振动隔离等各种方法都是提高精度的被动方案,机械方面的优化和提高是有限度的,而且有些情况下成本高昂。 设计高精度设备有一条重要的原则“设计和...
J. De Maeyer, P. Rombouts, L. Weyten, Addressing static and dynamic errors in bandpass unit element multibit DAC’s, in Proceedings of the 2004 International Symposium on Circuits and Systems , vol. 1, pp. I–345 – I–348, 2004...
Gear engagement model, high contact ratio gears, static and dynamic transmission model, low noise and vibrationIn high precision and heavily loaded spur gears the effect of gear errors is negligible, so the periodic variation of tooth stiffness is the principal cause of noise and vibration. High ...
Absolute and relative errors upper bounds are found respectively in the range [0.7° ÷ 8.2°] and [1.0° ÷ 10.3°]. Alongside dynamic, static accuracy is thoroughly investigated, also with an emphasis on convergence behavior of the different algorithms. Reported results emphasize critical issues ...
The aim of this study was to investigate static and dynamic visual acuity, refractive error, and the use of visual compensation of elite football players.From 2015 to 2017, 147 professional players from five teams were analysed. Screening consisted of a survey about the use of visual correction...
This paper presents a control mode of STATCOM, which has a fast dynamic response, zero static error, compensate unsymmetrical load. 提出了一种动态响应快,无静态误差,可用于补偿不对称负载的STATCOM的控制方法。 www.dictall.com 7. If there is a mixture of these types, or if other values of othe...
MessageId: DTS_E_EXPREVALSTATIC_FUNCTIONCONVERTPARAMTOMEMBERFAILED MessageText: A function parameter cannot be converted to a static value. The parameter must be static and cannot contain dynamic elements such as input columns.
(i.e. post-decision drift rate is high) model predicted confidence strongly dissociates between corrects and errors, reflecting good metacognition (Fig.1B, right panel). From the above, it becomes clear that we can use the strength of post-decisional evidence accumulation as a dynamic measure ...
Dynamic Phase Max Length的具体意义为:在Dynamic Phase Max Length范围以内,差分线的误差可以超过Tolerance。但如果在Dynamic Phase Max Length规定的长度内仍然未能将误差补偿,则给出一个DRC错误。 Dynamic Phase的应用举例来说. 设定Tolerance为x mil,Dynamic Phase Max Length为y mil。则Dynamic Phase的功能...
Using a finite element model, the influences of the structural modules on the static and dynamic characteristics of the lathe were analyzed, considering the effects of the workpiece load. The results indicated that the fundamental vibration modes of the lathe were primarily dominated by headstock, ...
