基于ADAMS的机械炉排系统驱动机构设计及运动仿真(英文)

炉排驱动机构带动机械炉排作往复运动,实现纵向和上下翻搅混合炉排床上的生活垃圾,同时纵向运送灰渣排出炉床。以设计符合生产实际的垃圾焚烧炉往复式机械炉排系统为目标,利用机械系统自动动力学仿真软件ADAMS平台,设计摇杆滑块机构和结构方案并建立多体动力学模型,加载近似实际工况边界条件,作驱动机构的动力学模拟仿真,得到运动过程中摇杆、滑块的运动规律和受力、位移、速度、加速度曲线,验证分析系统的运动平稳性和设计合理性,为驱动机构的结构优化设计和运动控制设计提供理论依据。

Design and Motion Simulation of the Driving Mechanism of the Mechanical Grate System Based on ADAMS

The grate driving mechanism has been designed to drive the mechanical grate to reciprocate,to make the MSW(Municipal Solid Waste) to be turned over longitudinal,up and down and to be mixed on the grate bed.Meanwhile,it discharges the ash longitudinally at the end of grate bed.This paper takes aim to design a reciprocating mechanical grate system for waste incinerator,which will meet the need of actual application.Based on the platform of mechanical systems,i.e.,automatic dynamic simulation software ADAMS,the rocker-slider mechanism and the structure of the program have been designed and the multi-body dynamics model has been established.The dynamic simulation of the driving mechanism has been done by setting up the approximate boundary conditions based on the actual working conditions.The law of motion,the force,the displacement,the velocity and the acceleration curves of the rocker and slider has been obtained.The smoothness of motion and design rationality of the system have been verified and analyzed.It provides the reference for the optimization of mechanism and the design of motion control.
