本文根据球面几何和球面三角学,建立了球面坐标系,以及刚体在球面上的位移公式。利用这些公式,研究了实现有限分离位置的球面四杆刚体导引机构的综合,并建立了球面上的布尔梅斯特曲线的三次代数方程和布尔梅斯特点的六次代数方程。
Based on the spherical geometry and spherical trigonometry, this paper established the spherical coordinate system and the rigid body displacement formula on the sphere. Using these formulas, the synthesis of the spherical four-bar rigid body guide mechanism with limited separation position is studied. The cubic algebraic equations of the Bümmeter curve and the six-degree algebraic equations of the Burmese characteristic are established.
