A series of topics such as lean design of automobile wiring harnesses are mainly reflected in the following aspects: ① The proportion of electronic and electrical products continues to increase. The core of new electronic products, such as electronic fuel injection, ABS, airbags and other control systems are all automotive electronic products. The speed of automotive mechatronics is accelerating. The working conditions of automotive electronic products are harsh, and the requirements for product performance and reliability are extremely strict. Once the product fails, it will pose a threat to safety, so the electromagnetic analysis and electromagnetic compatibility (EMC) research of automobiles have been put on the agenda. EMC research involves multidisciplinary cross-analysis of electricity, magnetism, heat, fluid, piezoelectricity and structure. Traditional finite element analysis software can no longer meet the requirements of lean design of electromagnetic products. ANSYS, a finite element analysis software with multi-physics field simulation function, provides suitable tools for this. In the design, the field-to-field combination method is used to simulate the electromagnetic field analysis of the motor to obtain the magnetic field distribution of the components, such as the air gap magnetic field, rotor torque, no-load and load characteristics to help product design. Using ANSYS analysis, the problem of nonlinear magnetic flow limit of oriented grain steel of the motor is easily solved, while increasing the magnetic density of the steel, reducing the loss of copper wire, and designing a lightweight motor. ② Nonlinear analysis has entered the practical stage. The essence of everything in the world is nonlinear, but it is often simplified to linear in traditional design. Now, lean design calls for nonlinear analysis.
The powerful and convenient nonlinear capabilities of the automotive Wiring Harness software meet this requirement. ③ System analysis is becoming more and more important in automotive design. There is generally no clear rule for the load transfer between related components, and the working conditions of individual components are not very clear, which adds difficulty to the analysis of automotive components; now the solution provided by ANSYS for the automotive industry allows the analysis object to be expanded to the assembly system and even the whole vehicle, thereby bypassing the problem of complex force relationships within the components, making the analysis results more realistic. ④ Combination of dynamic analysis and elastic body analysis. Traditionally, the object of dynamic analysis can only be a rigid body, and the elastic body of stress analysis can only be constrained. The dynamic analysis of the suspension system now does not need to rigidify the components of each mechanism. It can analyze its motion and stress response during working time while considering the structural elasticity, which can greatly improve the analysis accuracy.
