摘要：
In view of the effects of hydraulic parameters of interconnected suspensions on the suspension responses, a four DOF hydraulically interconnected suspension half car roll frequency domain model was established. According to the system transfer function and road inputs the bounce acceleration power spectrum density and roll acceleration power spectrum density were calculated. By using the sensitivity analysis method based on fuzzy grey correlation, the influence degree of hydraulic parameter on bounce response and roll response was carried out. NSGA-II method was used by taking as optimization object under two modes suspension responses. The obtained results indicate that the peak value of acceleration power spectral density is decreased as well as the acceleration root mean square value of the acceleration, and the ride comfort of the hydraulic interconnected suspension is improved. © 2017, China Mechanical Engineering Magazine Office.
