摘要
本文将平面铰链四杆机构的研究方法推广到球面四杆机构中,在有关球面四杆机构的研究基础上,讨论了上述两种机构在空间模型、分布子域、机构基本类型以及三坐标平面区间图的建立诸方面的同一性。建立了球面四杆机构的尺寸组合与空间模型上点之间的对应关系,进而讨论了球面四杆机构的尺寸型。由于所述两种机构各有其特点,文中还就两种机构在使用空间模型及三坐标平面区间图的不同之处给予了说明。
In this paper, the approach to planar four-bar linkage is introduced to spherical four-bar linkage. On the basis of the relevant studies of spherical four-bar linkage,the identities of the two above mentioned linkages with each other in the respect of space model ,subre-gion, dimensional type, and the establishment of three-coordinate-district-figure are discussed. The relationships between the points in space model and the dimensional classification of spherical four-bar linkage are also established. Because of the different behavior of the two linkages, the different manner of using the space model and the three-coordinate-district-figure is illustrated.
