Kinematic and dynamic analysis are crucial to the design of mechanism and machines. In this student-friendly text, Martin presents the fundamental principles of these important disciplines in as simple a manner as possible, favoring basic theory over special constructions. Among the areas covered are the equivalent four-bar linkage; rotating vector treatment for analyzing multi-cylinder engines; and critical speeds, including torsional vibration of shafts. The book also describes methods used to manufacture disk cams, and it discusses mathematical methods for calculating the cam profile, the pressure angle, and the locations of the cam. This book is an excellent choice for courses in kinematics of machines, dynamics of machines, and machine design and vibrations.... by an information device such as a template (master cam), which is often made several times actual size to increase accuracy, or by punched tape. ... 10-19a and is the distance from the cam center 0 to points on the pitch curve. r = R, + s (10-15 ) R, is the radius of the base circle. Example 10-4 A cycloidal cam with a reciprocating radial roller follower has a rise h of 20 mm in an angle B of 75Ad.
