由于解析法进行机构运动分析时,需要对位移关系式二次求导,求解过程复杂而又抽象,为此,本文着重介绍了一种新的方法避开复杂的二次求导,即根据速度多边形、加速度多边形直接列出速度、加速度的函数关系式,这种方法形象直观,简单方便,不易出错。现以滑阀泵为例,进行运动分析,然后介绍一种动平衡方法,即计算出平面运动的构件在转轴运动一周内沿转轴的平键方向、以及垂直于平键方向的两个平均惯性力,配重块产生的离心力等于这两个平均惯性力的合力时振动最小。
Due to the analytic method for the analysis of mechanism movement, the displacement relation needs to be derived twice and the solving process is complex and abstract. Therefore, this paper focuses on introducing a new method to avoid complicated quadratic derivation, that is, Polygons, acceleration polygons directly listed speed, acceleration function, this method is intuitive, easy and error-free. Now take the slide valve pump as an example, carries on the movement analysis, and then introduces a kind of dynamic balance method, namely calculates the planar movement the component in the axis of movement in a week along the axis of the flat key direction, and perpendicular to the flat key direction of the two average inertia Force, the weight generated by the centrifugal force equal to the average force of these two average force when the minimum vibration.
