Walking Mechanism

According to the principle of double-half-revolution mechanism, a new kind of quadruped-imitating walking mechanism was designed. In order to simplify the structure of the walking mechanism, each links of the mechanism is driven directly by steering gear.Considering non-interference condition of each links and undulation requirement during movement, the constraint functions were established. In order to ensure the movement feasibility and reduce the undulation of the walking mechanism, optimization design for the size parameters of each links were completed by using Matlab optimization tool. The virtual prototype model of quadruped-imitating walking mechanism was set up in SolidWorks software, and the rationality of the optimization design was verified through the simulation analysis.

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%.
