【正文】 of the mechanism are called kinematics dimensions(運(yùn)動(dòng)學(xué)尺寸 ). BAAB(a)(b) Distance LAB between the centres of the two holes in the coupler is the only kinematics dimension. BAAB(a)(b) Difference between “synthesis(綜合 )” and “design” : Dimensions(尺寸 ) affecting(影響 ) the motion of the mechanism are called kinematics dimensions(運(yùn)動(dòng)學(xué)尺寸 ). BAAB(a)(b) The radius of the hole is not a kinematics dimension!!!!! BAAB(a)(b)? “Synthesis (綜合 )” is the process of determining only the kinematics dimensions of a mechanism required to produce a particular (特定的 ) motion. ? “Design” is the process of prescribing the sizes, shapes, material positions(成分 ), arrangements of parts, calculations of strength(強(qiáng)度 ), methods of production etc. Purpose It is hoped that, after studying this textbook, the student will grasp(掌握 ) the basic theory and obtain the basic knowledge and skills(技能 ) needed in mechanisms synthesis and kinematic and dynamic(動(dòng)力學(xué)的 ) analysis of machinery. The knowledge to be obtained from this textbook is therefore fundamental(基本的 ) in analyzing existing(現(xiàn)有的 ) machines and designing new ones.
