Vibration Parameters Optimization Experiment on Seeder of Rice Bud-seed for Field Seedling Raising Based on Virtual Prototyping Technology

摘要：

　　The seeder of rice bud-seed for field seedling raising is a new seedling equipment for field seedling raising,which is a complicated vibration system with multi-freedom.And the effect of the vibration parameters and interactions on the vibration velocity at different locations of the moving rail of two electromagnetic vibration metering devices which are installed side by side is large,and the passing rate of seeding is affected.In this paper,the virtual prototype of seeder of rice bud-seed for field seedling raising is established by ANSYS and ADAMS.The virtual prototype is developed to carry out dynamics simulation by using four-factor quadratic regression orthogonal rotary combination design.Mathematical models of influencing factors of vibration and variation coefficient of vibration velocity,and the factors and average velocity of seeding are established.The factors are optimized.And optimal combination of vibration influencing factors and the variation coefficient of vibration velocity interval with 95% reliability are achieved.The result shows that optimal combination of factors is achieved under the condition that the excitation force amplitude is 39.8N,vibration frequency is 32.7Hz,the velocity is 58.5mm/s,stiffness of vibration isolating rubber pad is 1167N/mm.The corresponding variation coefficient of the vibration velocity is 6.287%,and the average seeding velocity is 18mm/s.The variation coefficient of the vibration velocity interval with 95% reliability is from 2.909% to 9.665%.
