The traditional bending-torsion combination experimental teaching has limitations in time and space, making it challenging for students to learn in depth. To solve these problems, a bending-torsion combination virtual simulation experimental platform is developed using UG NX10.0 and Unity3D software. The platform adopts a service-oriented software architecture design. It is designed with reference to the layout of the Mechanics Laboratory of Xinjiang University. Moreover, it provides two types of strain rosette virtual simulation experiments at 45° and 60°. The system module design is more intelligent. The application results show that the development of this platform expands research angles and operational forms of the experiment and meets the requirements of controllable cost, safety, flexibility, intelligence and innovation education. It also offers new perspectives for the development of other engineering virtual simulation experiments.
