【Abstract】 This article is focused on the extended research , Photoelectricity Multifunction-Measurement Machine , an importment project of "the Ninth Five" of Nation Defence Technology and Projects Commission. It is a comprehensive project, which involves several fields such as Optics, Mechanics, Electuonics, and Computer.In this article, a part of this project is described; it is non-contacted measurement system for spline radial circle-jumped error of the crank measuring machine. Because it is difficult to measure the radial circle-jumped error of this special shapde object by usual methods. A laser non-contacted measurement based on the optical-triangle principle is put forward, it has the advantage of high precision, highspeed, and on-line detecting. And it also has good flexibility, can be applied to the automatic production in defense industries, and in the civilian industries.According to the optical-triangle measurement principle, the overrall project design is given out; it includes optical-triangle-measurement head, optical system, fine mechanical system, computer control system, and data processing and comtrolling program. According to the overall project design, further study in the error analysis is discussed, and an improved design is put forward, with which, experimental measurement and data analysis is carried out.Through the theoretical analysis and experimental verification, the design of this measurement apparatus is reasonable, and the precision is also adequate.更多还原
