本文所介绍的矢量分解器是为平衡多拐(四拐以上)曲轴而制作的专用设备。文中就矢量分解的原理、力矩平衡方程式的建立和方案中各部分的工作原理作了详细的叙述。同时对影响本设备精度和稳定性的主要部份提出了具体要求,并对其具体线路也作了介绍。这是一种不受曲拐数限制,并能作定点分解和任意角度分解的通用方案。 The vector resolver described in this article is a special device made to balance multiple crankshafts (four cranks). In this paper, the principle of vector decomposition, the establishment of torque balance equation and the working principle of each part of the program are described in detail. At the same time on the impact of the accuracy and stability of the main parts of the equipment put forward specific requirements, and specific lines are also introduced. This is a universal scheme that is not limited by the number of bends and can be decomposed point by point and at any angle.
