为了获得树莓振动采收时的工作参数，选取果枝振动夹持位置、振幅、频率为影响因素，树莓的采收率、采青率为性能指标，采用二次正交旋转组合试验方法，建立了各因素与采收率、采青率的数学模型。同时，通过响应曲面分析各因素对各性能指标的影响，并对采收参数进行优化，获得振动采收的最佳工作参数。结果表明：当振动频率15～19 Hz、振幅21～26 mm、振动位置0．5时，树莓的采收率大于70％，采青率小于16％。试验所获得的振动采收工作参数为树莓采收机械的研制提供了依据。

In order to obtain the outstanding performance and the optimal parameters of the raspberry harvesting mecha-nism, quadratic orthogonal rotational combinational design was conducted.The factors in this research were selected as location , amplitude and frequency .Raspberry harvesting rate and immature raspberry harvesting rate were objective inde-xes.The regression models between indexes and factors were developed by using design-expert software.The interactions of factors on the indexes were analyzed by the response surface method.An optimum combination of input parameters was obtained with the region of frequency 15~19Hz, amplitude 21~26mm and a location of 0.50.The optimum combina-tion parameters may result in the raspberry harvesting rate above 70%, immature raspberry harvesting rate under 16%. The results offer the information for the development and design of raspberries harvest mechanical system.
