气动盘阀驱动链的设计简析

Design and Analysis of Drive Chain for Pneumatic Disc Valve

本文在气动盘阀驱动链的结构原理和开关转矩计算的基础上,以优化制造成本、提高结构强度和刚度、减小运动冲击为研究目的,以气缸行程、气缸输出力、固定架长度为研究对象,通过几何建模和数值计算的方法分析了气缸输出力初始方向与气缸行程、气缸输出力大小之间的关系,借此优化了执行器的制造成本;同时讨论了活塞杆与摇臂的角度设计对盘阀固定架长度的影响,并提高了固定架的结构强度和刚度,减小了冲击载荷对固定架的影响。

Based on the structural principle of drive chain for pneumatic disc valve and the calculation of switching torque,This paper purposes to optimize the manufacturing cost,improve the structural strength and stiffness,and reduce the motion impact.Taking the cylinder travel,cylinder output force,and the length of fixed frame as the research objects,the initial direction of cylinder output force and cylinder stroke,cylinder output force are analyzed by geometric modeling and numerical calculation.Meanwhile,the influence of the angle design for piston rod and rocker shaft on the length of disc valve fixing frame is discussed,which improve the structural strength,stiffness,and reduce the influence of impact load on the fixing frame.
