摘　　要：在简述涡轮增压器加速性内涵及其意义的基础上,分析了Karl Zinner提出的涡轮增压器加速性能参数B并进行改进,提出了新的涡轮增压器加速性能参数A。耦合应用GT-POWER与MATLAB/SIMULINK控制模块建立了涡轮增压器仿真模型,定量研究分析了瞬态加速过程中涡轮流量、温度和增压器总效率等因素对A的影响。最后,综合比较加速性能参数A中涉及的各影响因素,提出应用层次分析法可以有效地对涡轮增压器的加速性能进行评价。Based on analyzing the transient response characteristic parameter B, put forward by Karl Zinner, and covered its shortage, a new modified parameter A was introduced. The turbocharger simulation model was established by coupling control modules GT-POWER and MATLAB/SIMULINK. Influences of these factors, such as turbine mass flow,temperature,turbocharger total efficiency, etc. on the parameter A in the process were studied quantitatively. Variable influencing factors involved in the transient response characteristic parameters A were comprehensively compared. It is concluded that the turbocharger transient response characteristics can be evaluated effectively by the proposed analytic hierarchy process （AHP）.
