An automobile passenger restraint system optimization method based on a CAE technology

The invention discloses a CAE (Computer Aided Engineering) technology-based automobile passenger restraint system optimization method. The method comprises the following steps of 1 inputting data; 2 CAD (Computer Aided Design) geometry; 3 a vehicle body motion curve; 4 the position of the dummy; and 5, basic constraint system parameters; and then establishing a CAE basic model 50FRB/64ODB, and carrying out damage comparison. The method has the effects of 1, optimizing the direction; 2, optimizing parameters; 3 optimizing level; 4, optimizing the matrix; optimizing a working condition DOE, andthen analyzing an optimization result, determining an optimal parameter of the optimization working condition, substituting the parameter into a verification working condition, verifying the working condition, and then determining an optimal parameter of the verification working condition. According to the CAE technology-based automobile passenger restraint system optimization method, a step-by-step orthogonal test design
