引言飞行模拟技术是现代化航空科学中的一项重要的实验方法,它在飞机、导弹、卫星等许多领域的新机研制、产品改型、生产检验、飞行训练等方面都起着重要的作用。模拟转台是在地面条件下,模拟各种飞行器等在空间条件的真实飞行姿态的转换装置,是用来鉴定产品动态技术指标的主要设备,目前国内外研制的模拟转台,其中有一项重要的技术指标,就是内中外三框轴中心线之不相交度,我厂与613所等单位研制的748B转台,其三框轴中心线之不相交度要求不大于0.1毫米,就此项技术指标检测方法,我们做了一探讨,谈一点肤浅的体会。748B三轴转台三轴相交度的测量原理
Introduction Flight simulator technology is an important experimental method in modern aviation science. It plays an important role in the development of new aircraft, product modification, production inspection and flight training in many fields such as aircraft, missiles and satellites. The analog turntable is a device that simulates the real flight attitude of various aircraft under space conditions under the ground conditions and is the main equipment used to identify the dynamic technical indicators of the product. At present, there is an important technology for the analog turntable developed at home and abroad Index, is the intersection of the center line of the three frame inside and outside the degree of non-intersection, I plant and 613 and other units developed 748B turntable, the center line of the three framed axis does not meet the requirements of not more than 0.1 mm, on the detection of technical indicators, We did a discussion, a little superficial experience. 748B three-axis turntable three-axis intersection degree measurement principle
