全尺寸飞行器地面振动试验数字化协同探索与实践

全尺寸飞行器地面振动试验是飞行器研制的必须试验，具有协调界面多、试验系统复杂、实施周期长、试验风险高等特点，面向先进飞行器高效协同研制需求，必须引入数字化手段提升物理试验能力。本文通过梳理传统模式飞行器地面振动试验流程，剖析数字化协同试验要素，从试验方案与实施流程的数字化、试验对象的数字化、试验系统的数字化等方面出发，探索并初步构建了全尺寸飞行器地面振动试验的数字化方案。结合某全尺寸火箭地面振动试验案例表明，当前数字化协同模式对降低试验风险、提高试验效率具有显著助益，未来需进一步推进数实融合仿真、应用平台开发，以推动该技术模式成熟落地。

Digital Collaborative Exploration and Practice ofGround Vibration Test for Full-Scale Aircraft

As a necessary test of aircraft development，the ground vibration test of full-size aircraft has the characteristics of multiple coordination units, complex system, long implementation time and high risk. Facing the need of efficient development of advance aircraft, it is necessary to improve the capability of the test, by introducing the digital means. In this paper, the flow of ground vibration test in traditional mode has been summarized, the elements of digital experiment has been analyzed and the digital test programme has been constructed preliminarily. Based on the application of ground vibration test on rocket, the significant benefits in reducing test risks and improving test efficiency of this mode are shown, and it is necessary to promote the development of digital real fusion simulation and application platform, to promote the implementation of this technology.
