中文摘要： 随着航天、军事等领域的迅速发展，机械装置频繁在高加速度承载条件下运行，部分器件所承受加速度值已达到15万g（重力加速度），因此高加速度承载能力测试非常重要。利用高速旋转产生向心加速度原理进行超高稳态加速度承载实验是目前国家标准规定的、具有较强应用前景的实验方法，其中大质量固体超高加速度承载实验是该领域的难点问题。转子部件是该类实验系统的核心，其动态特性直接影响实验系统的测试能力和稳定性。本项目以影响转子动态特性的几何形状和制造误差为研究对象，综合数值计算算法和解析计算方法的优点，提出以协同算法为核心的转子部件优化建模与求解方法，探索复杂载荷作用条件下的形状优化方法。通过分析转子部件整体动态误差形成规律，揭示其对系统动态特性的作用机理，确立动态误差补偿策略，实现干扰因素的主动控制。搭建转子部件超高稳态加速度动态特性实验测试平台，分析转子部件对实验系统动态特性影响规律，为系统整体优化奠定基础。

The experimental method of superhigh stable acceleration bearing capacity is endowed based on the principle that centripetal acceleration is created at high rotary speed and is stipulated by national standards. The superhigh stable acceleration bearing capacity experiment of a heavy mass is the difficult problems in the field. Rotor parts are the core of the experimental system, and the testing capacity and stabilization of the experimental system is affected by dynamic characteristics of rotor parts.
