Matrix Differential

Techniques for the solution of linear matrix differential equations have previously been applied to the dynamic analysis of a mechanism. However, because the mechanism changes geometry as it rotates, a large number of solutions are necessary to predict the mechanism’s elastic behavior for even a few revolutions. Also, a designer is frequently concerned with the elastic behavior of only one point on the mechanism and has no practical interest in a complete solution. For these reasons, a method is given here for reducing the total number of coordinates to one coordinate at the point of design interest. A considerable saving in computational time is obtained since the dynamic solution involves one degree of freedom instead of many. Further, since any solution will make use of some limiting assumptions, results here indicate that, for design purposes, reducing the coordinates does not significantly affect comparable accuracy.

Elastic Link

Previous work on the analysis of elastic link mechanisms has been enlarged upon so as to include the effect of intermittent separation and impact between members. A cam-driven valve train is used as an example to demonstrate the methods for analyzing an elastic machine with clearances. Also demonstrated is a method for bookkeeping, or keeping track of the various configurations which the machine can assume due to the clearances. The methods presented here are sufficiently general to be applied to a variety of machinery; however, a cam-driven valve train was selected as an example because (1) it could be represented by a relatively simple elastic model, thus reducing the size of the computer program, and (2) an essentially constant geometry could be assumed, thus saving considerable computational time.

Rare Earthquake

For a super-long-span cable-stayed bridge, it is often required that the main tower be essentially elastic under a strong earthquake. Therefore, a seismic isolation structural system is often used to reduce the seismic response. Since the seismic displacement at the end of the deck may severely exceed the allowance, the elastic link device and viscous damper are often employed to control the displacement. In this article, a new damper (Metal Alloy Brace) is used to achieve this goal. Under the frequently occurred earthquake excitation, MAB’s hysteretic curve is plump, so the structural deformation is reduced. Under rare earthquake excitation, MAB can supply so big stiffness that the structural deformation is limited, and the damper will also dissipate much energy. And the damper has no problem with leakage and metamorphism. So, the prospect of MAB is brightening.
