Kinematic Analysis of Parameters of a Small-sized Potato Digger

Kinematic analysis of mechanisms is one of the types of study of the function of movement in time without taking into account the force factors affecting their links. It is known that in the framework of the kinematic analysis of the mechanisms of tension in the plane, the following problems are solved: identify possible cases of all links of the mechanism in the considered time interval; determine the values of linear absolute and relative velocities and accelerations of the characteristic points of the mechanism, as well as the values and directions of the angular velocities of all links; Usually, in the kinematic analysis of mechanisms, analytical, graphical and grapho-analytical methods are used. Now, with the help of computer equipment and programs, it will be possible to identify this problem clearly and in a short time. For example, let's look at the iterative determination of velocity and acceleration using SolidWorks Motion. To take full advantage of the existing functionality of the program, it will be necessary to provide analytical expressions for how it is built on the basis of analytical dependencies, as well as finding the speed and acceleration of a particular type of movement. This article provides information on the kinematic analysis of the main mechanism of a small potato digger, aggregated with a walk-behind tractor for digging out potatoes, using the SolidWorks software. On the basis of the given initial conditions, graphs of the acceleration and acceleration of the mechanism joints were constructed, and the values were determined and analyzed.
