摘　　要：现有气道稳态性能评价方法需要先得到多个行程下的特性参数,再按照一定的步骤计算得到最终的气道特性参数,导致试验或仿真时间较长,需要多次反复才能得到最终气道特性参数。提出了一种新型的气道稳态性能评价方法,只需要得到无气门时的气道特性参数,即可直接得到最终气道特性参数。结果表明:所提方法可以大大加快最终气道特性参数的获得速度,减少试验或仿真次数,并能取得与现有气道评价方法类似的气道评价结果。The existing methods for evaluating the steady state performance of port need to obtain the characteristic parameters at multiple valve lifts first,and then calculate the final characteristic parameters of the port according to certain steps,which results in long experimental or simulation time,and requires multiple iterations to obtain the final port characteristic parameters.A new method for evaluating the steady state performance of the port was proposed,which can directly obtain the final characteristic parameters of the port as long as the port characteristic parameters were obtained without the valve.Results show that the proposed method can greatly accelerate the acquisition speed of the final characteristic parameters of the port,reduce the number of tests or simulations,and achieve port evaluation results similar to the existing evaluation methods.
