How to Simplify the Jaw Crusher When Build Model for It

Jul 24 2014

Jaw crusher’s structure is much simpler than other crusher’s. But even this, it also needs to be simplified when then build model for it. If you want to build a model for the jaw crusher in ADAMS, you need just build the main moving parts of the crusher instead of its all parts, such as the eccentric shaft, the movable jaw plate, the toggle plate, and the frame. However, how to simplify the jaw crusher when build model for it? I will you introduce it to you in detail.

The simplification of the eccentric shaft

The eccentric shaft is an important component to achieve complex swing of the movable jaw plate, and has a very important impact on the moving characteristics of the mobile jaw plate.

The simplification of the movable jaw plate

The movement of the jaw crusher’s jaw plate is complex, so it is difficult to direct make a model in ADAMS. We simplify it to a connecting rod whose one end is connected with a hinge, and the other end is connected with the thrust plate by a hinge. Its length is equal to the length between the axis’ and the centerline of the movable jaw plate and thrust plate.

The simplification of the toggle plate

The toggle plate can be simplified as a a connecting rod whose one end is connected with the movable jaw plate, and the other end is connected with the frame.

The simplification of the frame

Build a model for the jaw crusher with ANSYS software, omitting fillets and chamfers, and some holes are also negligible, so that the frame can be simplified a link.
