APM Dynamics - a product designed to solve the problems of modeling the dynamics of spatial mechanical systems by the finite element method (FEM).
The application of the MCE made it possible to abandon the representation of dynamical systems in the form of absolutely rigid bodies, as assumed in classical mechanics, and take into account the elastic properties of these bodies. The elastic properties of dynamical systems are automatically formed, which greatly simplifies the practice of applying the proposed method.
The geometry of the elements of mechanical systems is created with the help of a modern three-dimensional graphic editor, in which there are both tools for geometric modeling, and means for specifying boundary conditions and sensors for recording the required output parameters.
The dynamic model is formed in the form of one-, two-, three- and n-mass systems (n is an arbitrary integer) and systems with distributed masses.
New algorithms have been developed to simulate the dynamics of inelastic mechanical systems. Equations of motion are effectively solved by the method of decomposition into its own forms, which has the following possibilities:
The proposed numerical approaches allowed us to describe satisfactorily the transient processes that occur during the movement of mechanisms and machines, which can not be achieved with the traditional representation of dynamic objects in the form of absolutely rigid bodies.
Realized solutions allow correctly describe the laws of motion in three-dimensional space as spatial mechanisms, as well as arbitrary mechanical systems.
APM Dynamics includes the following tools:
