【摘要】：速度平滑問題是高速數(shù)控加工及煤礦提升機(jī)為提高加工精度與設(shè)備壽命而提出的,針對(duì)該速度平滑問題建立分段模型,基于加速度與速度的關(guān)系,推導(dǎo)了各段速度、行程和時(shí)間的解析解,推導(dǎo)了模型中關(guān)鍵一元三次方程的通用解,并將其運(yùn)用到速度平滑分段求解問題中。本方法應(yīng)用于煤礦提升機(jī)速度平滑問題中,顯示出易于程序?qū)崿F(xiàn)、計(jì)算量小、過渡曲線平滑的特點(diǎn),能很好適應(yīng)高速運(yùn)動(dòng)設(shè)備速度平滑的場(chǎng)景。目前該方法已推廣至多個(gè)實(shí)際項(xiàng)目中。
[Abstract]:The speed smoothing problem is proposed by high speed NC machining and coal mine hoist to improve the machining accuracy and equipment life. A segmental model is established for the speed smoothing problem. Based on the relationship between acceleration and velocity, the velocity of each segment is deduced. The general solution of the key cubic equation in the model is derived and applied to the speed smoothing piecewise solution. This method is applied to the speed smoothing problem of coal mine hoist, which shows that it is easy to be realized by program. Because of its small computation and smooth transition curve, this method can be well adapted to the scene of high speed motion equipment with smooth speed. At present, this method has been extended to many practical projects.
