矩法评定活塞裙部横截面线轮廓误差
Study on the Evaluation of Piston Skirt Cross- Section Contour Error with Moment Method
【摘要】 本文通过组合应用矩法与最小二乘法,提出了求解被测活塞裙部横截面理想线轮廓的方法,并对评定活塞裙部横截面线轮廓误差进行了讨论。
【Abstract】 With the combined application of moment method and least square method, both the determination means of the ideal linear contour of the surveyed piston skirt cross-section and the evaluation of piston skirt cross-section contour error have been put forward and discussed respectively in this paper.
