摘要
对一种变行程可调机构的性能与结构参数间的关系进行了详细的研究。给出了解析运动模型 ,研究了在不同杆长条件下机构的行为 ,特别分析了不同的结构参数选择所导致的具有显著差异的机构输出运动。揭示了机构的性能与结构参数间的关系 ,可用于指导该机构的设计。这种机构可应用于计量泵中 。
Adjustable mechanisms make it possible to use the same hardware for different input output relationships.The aim of this paper is a detailed investigation into the relationship between performances and structural parameters of an adjustable mechanism with variable stroke.The analytical kinematic model is established.The system behavior is studied under different ratios among the mechanism rod lengths.In particular the noticeable different effects produced on the output movement by different choice of structural parameters are illustrated.The relation between performances and structural parameters of the mechanism is revealed,which can be used to guide the mechanism design.This mechanism can be applied to metering pumps,because it allows the piston stroke to be adjusted in length and permits the pump flow to be changed during the pump functioning.
