高速试验滑轨是一种大型地面动态模拟试验设备,主要用于研究试验件在空中高速度、高加速度运行时所遇到的诸多技术问题,其核心技术是十万分之一的直线性相对精度。本文较为详细地阐述了滑轨子系统、承载梁子系统以及高精度测量子系统的设计原理和要点。其中双向受力锚固机制、承载梁子系统中的整体式道床方案以及高精度激光跟踪仪技术均为该领域的创新技术。
High-speed test slide is a large ground dynamic simulation test equipment, mainly used to study the test pieces in the air at high speed, high acceleration operation encountered many technical problems, the core technology is one hundred thousandth of the linear relative Accuracy. This paper elaborates the design principles and key points of the slide rail system, bearing beam subsystem and high-accuracy measurement subsystem in more detail. Among them, the bi-directional force anchoring mechanism, the integrated track bed scheme in the bearing beam subsystem, and the high-precision laser tracker technology are all innovative technologies in this field.
