Dynamic analysis of mechanical transmissions - Form of results representation

The form of calculation results representation

The dynamic analysis of the mechanical and hydro mechanical drive scheme results can be presented either in a tabular-numerical form (listing), or in the form of graphs of the required dependences.

The tabular -numerical form of calculation results (output listing) is constructed as follows. As in each node of the mechanical and hydro mechanical drive scheme the following combinations of physical variables are possible: « force – linear speed – linear displacement», « torque moment – angular speed –turn angle», it is possible to pass to the integrated system of physical variables: "forces" (forces, torque moments), "speeds" (linear or angular ones), "displacements" (linear or angular ones), which are indexed under numbers of the scheme nodes. According to it the structure of the calculation results, presented in output listing, is those:

 Time, s

Number of node            "force"            "speed"            "displacement"

Number of node            "force"            "speed"             "displacement"

.         .        .         .        .        .         .        .        .         .        .        .        .

Number of node            "force"           "speed"            "displacement"

_________________________________________________________________

Time, s

Number of node            "force"            "speed"            "displacement"

Number of node            "force"            "speed"             "displacement"

.         .        .         .        .        .         .        .        .         .        .        .        .

Number of node            "force"           "speed"            "displacement"

_________________________________________________________________

Time, s

Number of node            "force"            "speed"            "displacement"

Number of node            "force"            "speed"             "displacement"

 .         .        .         .        .        .         .        .        .         .        .        .        .

Number of node            "force"           "speed"            "displacement"

_________________________________________________________________

That is, with the certain time step for each number of node the three values stands out: "force", "speed", "displacement", defining for the given moment of time values of the physical variables operating in the given node. These records stand out until the time interval given for calculation is settled, or there is no emergency stop of the program. In both cases all last data describing the system condition (control point), are remembered by the program and since this time moment it is possible to continue calculation, giving the longer time interval. Certainly, the emergency stop of the program will demand check of the created situation and its correction for the further continuation of calculation.
