Abstract: To solve the nonstandard management of gear basic data and function deficiencies in domestic gear software,a High-Performance Gear Transmission Database and Design Software (HPGTDS) was developed by using the C++ programming language,the Qt application framework,and the SQLite database engine.HPGTDS was applied in the gear industry for design,analysis,and production management,enabling high-efficiency flow management and scientific data analysis of gear materials,manufacturing processes,gear structures,and operating performance.The gear transmission system design module including working-condition analysis,cycle-life prediction,bearing selection and structure optimization functions was developed,thus the design and multi-objective optimization of gear transmission systems with complicated variable boundary conditions were realized.HPGTDS was successfully applied in the weight reduction of a co-rotating twin-screw gear transmission system and a heavy-duty gear database of vehicles,providing effective support for the high-performance gear industry.
