Abstract: Structural analysis CAE software is an important means of core technology research, a fundamental guarantee for major equipment development and key support for intelligent manufacturing advancement. The high-level autonomous and controllable (aviation) structural analysis CAE software is of great strategic significance to the leading innovation of aviation science and technology, and the integrity and safety of the equipment development system. By deeply combing the development process of domestic and foreign structural analysis CAE software deeply, this paper systematically analyzes the general development law of this software. Moreover, the challenges of this software are also pointed out from four dimensions, i.e. the complexity of the software itself, research and development cycle, the requirements of equipment, and the reliability. Meanwhile, the generalized connotation, overall idea and key technology of autonomous (aviation) structural analysis CAE software development are put forward from such three levels as the general analysis function group, special analysis tool chain and domestic data resource pool. Finally, based on the current world and national condition of industrial software and the law of scientific development, the prospect of autonomous controllable (aviation) structural analysis CAE software is offered.

Key words: Computer aided engineering, industrial software, aviation structure, general software, aviation special analysis software, CAE
