摘要: 针对茶叶抖筛机的主要设计参数，建立了茶叶抖筛机优化设计数学模型，运用蚁群算法和Matlab语言，编制了茶叶抖筛机的关键参数的优化程序，运用该程序对茶叶抖筛机的筛床倾斜角、振动方向角、曲柄半径、振动圆频率等参数进行优化仿真计算和验证试验。结果表明：筛床倾斜角α为2.8^°；振动方向角β为52.8^°；曲柄半径r为0.025 m；曲柄圆频率ω为21.5 rad/s时，筛净率提高14%，单位有效筛分面积生产率提高28 kg/(m²·h)。

Abstract: Mathematical model for tea vibrating-shifting machine optimum design was established in this paper. Based on the ant colony algorithms and Matlab, the realization programs for parameters simulation of tea vibrating-shifting machine were made. The programs were used in optimization simulation and verification tests of tilt angles, direction angles, crankthrow, and vibration palstance. The results showed: when tilt angles α were 2.8^°, direction angles β were 52.8^°, crankthrow r was 0.025 m, vibration palstance ω was 21.5 rad/s, the sieve ratio was increased by 14% and the productivity of unit sieving area was increased by 28 kg/(m²·h).
