The invention is suitable for the technical field of computers, and provides a racing car frame performance analysis method, device and equipment and a storable medium, and the method comprises the steps: building a car frame model according to racing car frame parameters and a preset competition rule; performing finite element simulation analysis on a full-load bending condition, a full-load torsion condition, an emergency braking condition, a high-speed turning condition, bending rigidity and torsion rigidity of the frame model according to a preset frame simulation unit, a frame simulationgrid size, a simulation load condition and a simulation constraint condition, and according to a simulation analysis result, determining the bending rigidity and the torsional rigidity; performing free modal analysis on the racing car frame model, determining the engine excitation frequency, and therefore a racing car frame performance analysis result is generated. According to the method, a complete and effective racing car frame performance analysis system is established, the problem that a detailed simulation and calculation method is lacked in the field of Bacha off-road car frame mechanical analysis is solved, the racing car can meet the strength requirement and the rigidity requirement, and the rationality, reliability and safety of car frame design are guaranteed.
Description
technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a performance analysis method, device, equipment and storage medium of a racing car frame. Background technique [0002] The Baja competition originated in the United States in 1976, and was introduced into my country by the Society of Automotive Engineers of China in 2015, and was named Baja SAE China (BSC for short). The event is a competition for the design, manufacture and testing of off-road vehicles participated by teams of college students, vocational colleges and related majors. The BAJA frame is an important part of the racing car, carrying the quality of each component. The design of the frame must fully comply with the rules of the Baja competition, and it must meet the requirements of strength and stiffness while achieving the purpose of reducing weight, and finally, the comfort of the car must also be considered. For off-road vehicles, it is especiall...
