摘　　要：在连续波发生器转阀设计中,仅以转阀的最大、最小通流面积为设计指标所得到的压力波信号畸变很大,不适合作为连续波信息传输的载波。为解决该问题,在最大、最小通流面积设计准则的基础上提出了相关系数最大的设计准则;建立了底边为直线的梯形阀口转阀通流面积的参数化计算模型;根据提出的设计准则建立了转阀阀口形状的优化模型。优化结果表明:该优化模型可以获得较理想的正弦波压力信号。为减少加工难度,对转阀的设计参数进行取整,并分析了参数取整对压力波信号特性的影响。The pressure signal is distorted extremely using the maximum and minimum flow area as the de- sign criterion in the continuous wave generator design, and is not suitable to be used as the carrier wave in the continuous wave information transmission. In order to solve this problem, The design criterion of maxi- mum correlation coefficient is proposed based on the maximum and minimum flow area criterion. The para- metric calculation model of rotary valve flow area of the trapezoid orifice with line bottom is established, af- ter that, the optimization model of the shape of rotary valve orifice is built up according to the criterion mentioned above. The optimization results show that the optimization model can get the better pressure signal. In order to reduce the machining difficulty,the design parameter of the rotary valve is regularized, and the influence of the parameter regularization on the pressure signal is analyzed.
