摘要：
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 Ι and class ΙΙ 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. © 2023 Chinese Mechanical Engineering Society.
