Determination and Performance Analysis on Miniature and Electric Commercial Vehicle Frames of Carbon Fiber Materials in the Laying Mode

Abstract

The concept three-dimensional model of the mini commercial vehicle was established, and the vehicle parameters and calculation conditions were defined. The stress direction and value of the beam were calculated by Ansys workbench, and the laying method of the carbon fiber material of the beam was determined to be [0°\\90°\\ 45°\\90°\\0°] of the five-layer layup sequence, using the Abaqus software analyzes the frame made of carbon fiber composite material. It is found that the degree of Hill failure is 23.88% on the beam 3 under the working condition 1, and the damage of the beam 4 is 33.92% under the working condition 4, and the damage degree is less than 100%. The modal analysis results of the whole frame show that torsional mode and bending mode frequency of the first-order are 51.741 Hz and 62.286 Hz, exceeding 48% and 58% of the target value, respectively, which meet the target requirements. Carbon fiber materials provide an important basis for the application of miniature commercial vehicle frames.
