The invention relates to the technical field of the computer aided engineering (CAE), specifically to a low-frequency vibration test system based on an automobile virtual prototype. The low-frequency vibration test system based on the automobile virtual prototype comprises an analysis project selecting module, a calculating module, a working condition calling module, an automobile type calling module and a result displaying module. The low-frequency vibration test system based on the automobile virtual prototype is capable of, sorting and displaying the test result according to the automobile type and test working condition, displaying the same working condition of the same automobile type in the same two-dimensional curve, avoiding the complicated operation of generating one curve for the loading of different loading points in the different working conditions of each automobile type, combining partial curves through the test working condition and displaying in the same curve, and conveniently performing the concentrated comparison of the result; and solving the problems that the elapsed time of the test process of the current low-frequency vibration test system is long, the result curves are independent mutually, and the results are inconveniently constructed to compare.
Description
technical field [0001] The invention relates to the technical field of computer-aided engineering (CAE), in particular to a low-frequency vibration test system based on an automobile virtual prototype. Background technique [0002] In order to test the performance of the vehicle, it is necessary to establish a finite element grid model with the help of CAE technology, and then establish a vehicle virtual prototype in the vehicle coordinate system of the finite element grid model, also known as a vehicle virtual model. The low-frequency vibration test refers to the response of the car after it is subjected to an external force. If it is tested with the help of CAE technology, it is necessary to first apply a load to the excitation point in the virtual prototype of the car, and then test the displacement and acceleration of the response point, as well as the noise at the response point. [0003] In the existing low-frequency vibration test system based on the automobile virtua...
