In the advanced development of a vehicle rear suspension, suspension K& C characteristic is defined as optimal design conditions for vehicle rear suspension hard point design and development. Based on engineering experience and features of four-link type suspension, suspension design parameters which have substantial influence on suspension K&C characteristic are chosen. By comparison and analysis, appropriate DOE approach, approximation model method and optimization algorithm are chosen for rear suspension hard point optimization, which improve the vehicle development efficiency.
