根据国务院关于在我国统一实行法定计量单位的命令及鞍山力值改制经验,对我厂WE-30,WE-100,ZDM-50三台拉力试验机、于85年6月完成了双力值改制任务。经实践,并通过锦州市计量检定部门鉴定,符合鉴定的公差要求。一改制方法由于拉力试验机原读数盘的刻度以千克力或吨力为单位,而改制后的读数盘的刻度以牛顿或千牛为单位。为了保持原读数刻度线位置不变,使得1千克力或1吨力的位置正好等于10牛顿或10千牛的位置,应增加拉力试验机摆砣的重量。 1 摆砣应增加的重量将力的计量单位由千克力改为牛顿其原理,是由
According to the State Council’s directive on the uniform implementation of statutory units of measurement in our country and the experience of restructuring of Anshan Power Company, we completed the restructuring of the Three-Force System in June 1985 for three tensile testing machines WE-30, WE-100 and ZDM-50 of our factory, task. After practice, and through the verification of metrological verification in Jinzhou City, in line with the identification of tolerance requirements. A restructuring method As a result of tensile testing machine original reading plate scale to kilogram force or ton of force as a unit, and after the restructuring of the reading plate calibration in Newton or a thousand cattle as a unit. In order to keep the position of the original reading tick unchanged, such that the position of 1 Kg or 1 Tk is exactly equal to 10 N or 10 KN, the weight of the tensile tester should be increased. 1 swing 砣 should increase the weight of the unit of force from the kilogram force to Newton’s principle is by
