摘要: 针对航空发动机机匣强度试验对多边并联加载装置的需求,基于六自由度并联机构提出了一种适用于机匣多边多维力加载的试验系统,在实现系统稳定加载控制的同时有效抑制了机匣柔性变形对多维力加载精度的影响。利用旋量理论推导得到了典型双边多维力加载装置的一阶静力影响系数矩阵,运用ADAMS和Simulink建立了机匣加载系统联合仿真模型,实现了支链力与多维力之间的映射和柔性变形补偿解算。考虑多维力加载装置的Ⅰ类和Ⅱ类误差影响因素,推导了机匣双边多维力加载装置的误差分析模型。在此基础上研制了机匣双边多维力加载装置样机,搭建了机匣多维力静态测量与加载试验系统,并进行了试验验证。根据试验结果分析得到了该系统的加载精度,从而为机匣多边多维力并联加载装置的开发与应用提供了参考。

Abstract: Aiming at the requirement of a multi-dimensional parallel loading device for aircraft engine casing strength test, a test system suitable for multi-dimensional force loading of the casing based on a 6-DOF parallel mechanism is proposed, which can realize the stable loading control of the system and effectively suppress the influence of the flexible deformation of the casing on the multi-dimensional force loading accuracy. The first-order static influence coefficient matrix of a typical double-sided multi-dimensional force loading device is derived from spinor theory. The co-simulation model of the cartridge loading system is established by Adams and Simulink, and the mapping between the branched-chain force and the generalized force, and the flexible deformation compensation are realized. Considering the error influencing factors of class Ⅰ and class Ⅱ of the multi-dimensional loading device, the error analysis model of the double-sided multi-dimensional loading device is derived. On this basis, a prototype of a double-sided multi-dimensional force loading device of the cartridge was developed, a static measurement and loading test system of the multi-dimensional force of the cartridge was built, and the test was verified. According to the test results, the loading accuracy of the system is obtained, which provides a reference for the development and application of the multi-dimensional parallel loading device of the casing.

Key words: casing, parallel mechanism, joint simulation, deformation compensation, multi-dimensional force loading
