Crank slider mechanisms with 0 and 1.25 eccentricity. A slider-crank linkage is a four-bar linkage with three revolute joints and one prismatic, or sliding, joint. The rotation of the drives the linear movement the slider, or the expansion of gases against a sliding in a cylinder can drive the rotation of the crank. There are two types of slider-cranks: in-line and offset.

(In this lab you will learn to use the software that accompanies the Norton text for doing velocity and acceleration analyses of a four-bar linkage. Appendix A in.
In-line: An in-line slider-crank has its slider positioned so the line of travel of the hinged joint of the slider passes through the base joint of the crank. This creates a symmetric slider movement back and forth as the crank rotates. Offset: If the line of travel of the hinged joint of the slider does not pass through the base pivot of the crank, the slider movement is not symmetric.
It moves faster in one direction than the other. This is called a quick-return mechanism. Spherical and spatial four-bar linkages If the linkage has four hinged joints with axes angled to intersect in a single point, then the links move on concentric spheres and the assembly is called a spherical four-bar linkage. The input-output equations of a spherical four-bar linkage can be applied to spatial four-bar linkages when the variables are replaced. Is a spatial four-bar linkage with hinged joints that have their axes angled in a particular way that makes the system movable. Hartenberg, R.S.

Norton Associates Engineering - Home What's New in Programs NEW COURSE. A web-based short course in cam design is now on this site. It offers eight, 1-hour lectures on cam design by Professor Norton based on his 50 years experience designing cams and teaching the subject. Professor access via email is also available along with the srteamed video. It also serves as a tutorial on program Dynacam. Use this link. Paypal can be used to purchase software from this site.
A purchase order, check, or wire transfer can still be used if preferred. All programs can now be network licensed on a Windows terminal server. Contact us for details. Dynacam and Dynacam Plus have been completely rewritten for compatibility with 64-bit Windows 7 and 8.Program Linkages replaces the programs Fourbar, Fivebar, Sixbar, Slider, and Engine and combines all those linkages in one package, which is compatible with 64-bit Windows 7and 8. Dynacam Plus includes a feature that allows a measured or empirical cam profile to be imported. The data is then splined and the cam functions created to analyze its dynamics or redesign it with better functions.
Dynacam Plus also allows the design of a cam-driven fourbar or sixbar linkage or slider follower train and can share data with program Linkages so that the cam-driven linkage designed in Dynacam can be dynamically analyzed in Linkages. What's New in Books. Norton's latest book, Automotive Milestones is now available for order at Amazon.com. This book explores the technological development of the automobile from its beginnings to the present. It tells the story of how the automobile's major systems and subsystems developed over time and explains how they work in layman's terms, without using complicated math. Combustion cycles, chassis layouts, engine types and designs, valve trains, transmissions, drive lines, suspension, steering, brakes, and body design - all are discussed in detail.
The 5th edition of Machine Design is now available and contains a new chapter on Linkage Design and Analysis as well as many new problems.Its web-based software now includes a series of Master Lectures by Professor Norton on the subject of the text. The 5th edition of Design of Machinery is now available and has the new program Linkages, and Dynacam on its DVD, which also contains a number of videos and tutorials plus Hrones and Nelson's Atlas of fourbar coupler curves. It also offers the download of a low-cost version of the Working Model program. The 2nd edition of the Cam Design and Manufacturing Handbook has new material on globoidal cams, torque-compensation cams, and multi-dof modeling of cam-follower systems. The latest student versions of Design of Machinery's programs can be downloaded from this site.
But, access is limited to professors who have adopted the book for a class. To request a password if you qualify.Student owners of Kinematics and Dynamics of Machinery can log in to download the book software.
