基于ADAMS的联合收割机振动筛虚拟设计

Virtual Design of Vibrating Sieve of Combine Harvester Based on ADAMS

基于 ADAMS软件 ,提出了一种对联合收割机振动筛进行虚拟设计的方法。在 ADAMS中建立了振动筛的模型 ,并进行了动态仿真分析 ,在不作任何简化性假设的条件下考察了筛面加速度的变化规律 ,选出了机构的关键参数 ,并结合 Fortran语言编程完成了筛上脱出物的运动分析 ,优选了机构的工作参数。

A virtual design approach to the vibrating sieve of combine harvester was put forward based on ADAMS. Realization of a virtual design process were described. A model of sieve was built and its dynamic simulation was made with ADAMS. The change of acceleration of sieve was analysed without any simplified hypothesis. The key parameters of the vibrating sieve were chosen through design study and the motion of corn straw mixture was analysed. Finally, the working parameters of sieve mechanism were optimized.
