Enabling Multi-Bar Design

The New Generation of Dynamic Mechanisms is Here Now

SyMech-NT Multi-Bar module makes complex mechanisms practical.

SyMech-NT is the add-on module you'll use to create mechanisms with more than one mechanical function (position, angle, path) or with more than four links.

Like SyMech's 4-BarT, Multi-Bar rapidly enables you to find the optimal solution to complex mechanisms. Multi-Bar is needed for anyone doing realworld designs. Even if you don't think you'll be designing a complex mechanism, often you'll find that as you search for ways to meet functional requirements, the best answer will be a mechanism with some element of complexity. For that, you'll need SyMech-NT.

Solving the Complexity of Multiple Mechanisms with SyMech-NT

Complex Mechanisms

The complexity of a mechanism grows rapidly with the number of functional parts. SyMech-N™ makes it possible to design simply, step-by-step, adding functional mechanisms to ones you've already designed.

Like SyMech-4™, upon synthesis, the optimal solution is immediately known — even for all the functional parts. Both the realtime animation and realtime analysis tools will work for the entire complex mechanism.

Designing Complex Mechanisms with SyMech-N™

Imagine that you will be designing the mechanisms to enable the Crystal Ball Toy shown here.

The specification from marketing might look like:

Create a child's toy that will turn itself off by hitting an off-switch on the outside of the toy container. This requires the following mechanisms and functions, several of which have combined functionality — a perfect job for SyMech-N™!

    •  switch — outside
    •  finger — inside
    •  lid — to close the container
    •  motor driven

The starting point is a 4-bar mechanism to describe the arm, which comes out and pushes a button. Fig. 1a shows the part and 1b shows the 4-bar schematic. This can be designed and synthesized as described on the SyMech-4™ product page.

Figure 1a	Figure 1b

Next, you need to add a lid mechanism that will move in conjunction with the arm. Fig. 2a is the lid and 2b is the schematic. SyMech-N™ is the way you create this mechanism. You'll do it by adding links to the arm mechanism, selecting the part, and designating the built-in mechanism template for it.

Figure 2a	Figure 2b

Each time you are increasing the level of complexity, but SyMech-N™ can handle it, telling you the optimal solution, letting you see the solution curve, and generating the realtime analysis of physical properties at joints. As with other SyMech™ products, anytime you drag and move the design on-screen, the solution, animation, and analysis are changing in realtime as well. SyMech™ brings the power of computing to solve the problem of dynamic mechanism design ... and you and your company benefit.

Finally, Fig. 3 shows the crank drive mechanism as it is added to the other two. SyMech-N™ allows you to designate which link should be the driving link for the mechanism.

Installation

SyMech-4™ installs easily into Pro/Engineer. It can be installed locally or be run from a network shared drive. The installation program does not require a reboot.
