【Abstract】 The key structural parameters of high-speed solenoid has crucial influence on high-pressure common rail injector response.With the MOSA(multi-objective simulated annealing) algorithm,the multi-objective optimization model,which took the delay of solenoid opening and closing and the electromagnetic force as objective functions,was built based on the modeFRONTIER multi-objective multidisciplinary optimization platform that was integrated with ANSYS finite element analysis software.With the model,the key parameters of high-speed solenoid were optimized.The results show that the delay of solenoid opening is 0.11 ms,which reduces by 15.4%.The delay of solenoid closing is 0.18 ms,which reduces by 25%.Besides,the electromagnetic force is 160 N,which increases by 12.5%.更多还原
