How to Check the Rationality of Design of Crusher
When we use 3D design software to establish the general assembly of the jaw crusher, it is intuitive and the designers can carry out the parametric design, strength, stiffness checking, interference checking and motion simulation to test the correctness and rationality of the design.
The first is the parametric design. The designers may need to improve and modify the crusher based on the designed crusher, which needs the parametric design to achieve the serialization of the products in order to avoid the repeatability of the design. The sketch for the 3D models and assemblies is variable and the sketch dimensions, features and fitting dimensions are parameterized driven, so it very convenient to achieve parametric design. You can take the following measures to achieve the parametric design of the crusher. First, you can directly modify the size, compress or add features. Then you can save it as a new part or assembly. Second, the 3D software design provides very convenient tools to generate different configuration of the part or assembly. Third, the software provides good API. The design staff can conduct the secondary development to achieve the parameterized design of the crusher
The second is the strength and stiffness checking. The crusher 3D models created by the software can set the material, which has certain physical properties and can check the strength and stiffness of the parts and the assembly of the crusher machine. The plug can carry out the static and dynamic finite element stress analysis for the parts of the crushers. The data is very accurate, which can be saved into a form of animation or web page.
The third is the interference collision checking. The soft ware provides the static interference checking and dynamic collision checking for the assembly to ensure that there is no mutual overlap between any two parts in the space. In addition, it can be used to dynamically simulate the movement effect of the parts in the crusher machine. The image is vivid image and we can timely find the problems to modify them.
The forth is motion simulation. The kinematic simulation of the structure of the crusher is achieved through the degrees of freedom of movement and parameters created and animated by the defined parts of the existing three-dimensional model of the crusher. It is created by animation way. You can see the real-time trajectory by using the plug in the software.
