摘　　要：目的:提高砻谷机脱壳效率。方法:模拟出稻谷脱壳过程,通过改变胶辊运动速度、线速差等参数分析各参数对脱壳工作的影响。首先在SolidWorks中建立砻谷机模型与单边带壳糙米模型,之后将建立好的模型导入ADAMS中进行仿真,通过改变快慢辊的转速、快慢辊之间的线速差、胶辊与谷壳之间的摩擦系数,观察相应因素对砻谷机脱壳效率的影响。结果:快慢辊转速越快,稻谷脱壳所需的时间越短;快慢辊线速差越大,稻谷脱壳所需的时间越短,但变化幅度很小;胶辊与谷壳间的摩擦系数越大,稻谷脱壳所需的时间越短,但变化幅度与改变快慢辊转速带来的变化幅度相比较小。结论:对于直径为225 mm,胶厚为25 mm,胶辊轧距为0.8 mm的胶辊砻谷机,脱壳效率最高时的快慢辊转速分别为16.5,13.4 m/s,胶辊与谷壳之间的摩擦系数为0.75。Objective:Improve the hulling efficiency of the rice huller.Methods:Simulated the process of rice hulling,and analyzed the influence of various parameters on the hulling process by changing the movement speed of the rubber roller and the line speed difference.Firstly,the model of huller and the model of single-sided shelled brown rice were established in SolidWorks,and then the established model was imported into ADAMS for simulation,and the effects of the corresponding factors on the hulling efficiency of huller were observed by changing the rotational speeds of the fast and slow rollers,the difference in line speeds between the fast and slow rollers,and the friction coefficients between the rubber rollers and the hulls.Results:The faster of the speed of the fast and slow rollers was,the less time was needed to dehull the rice.The larger the difference between the linear speed of the fast and slow rollers was,the less time was needed to dehull the rice,but the change was very small.the larger the coefficient of friction between the rubber rollers and the hulls was,the less time was needed to dehull the rice,but the change was small comparing with that brought about by the change in the speed of the fast and slow rollers.Conclusion:For the diameter of 225 mm,rubber thickness of 25 mm,rubber roller rolling distance of 0.8 mm rubber roller huller,shelling efficiency was at the highest speed of the fast and slow roller speed of 16.5 m/s,13.4 m/s,the friction coefficient between the rubber rollers and hulls for 0.75.
