JOINT APM - calculation module and design of machine elements connections

APM Joint - Elements and units of the machines, mechanisms and constructions are joined together by means of the special elements or without them, producing new constructions and units as the totality of the smaller ones. There are many ways of element joining and many methods of the calculation and the design of such joints. Different types of machine element joints are used in the mechanical engineering— threaded,welded, riveted, keyed, splined, etc. You can design and calculate all these objects with the APM Joint. APM Joint is a software for the machine element joints calculation and design. It allows to perform a complex calculation and analysis of the most widely used types of joints. The use of this software reduces design time, increases design reliability and efficiency, helps to select the optimal decision.

APM Joint can calculate the following joints

Threaded opened and closed joints , with any element arrangement, arbitrary configuration of surfaces to be joined and arbitrary loading In addition bolts, screws and studs can be calculated as fastening elements under arbitrary external load

Welded joints  with the arbitrary arrangement of seams under the arbitrary external load, including butt joints - tee joint - lap joints joints produced by the spot weld. riveted joints of the arbitrary arrangement under the arbitrary plane loading

Joints of the rotating elements  such as - interference fits of the cylinder and cone shape - splined and keyed joints - radial and axial pins (gluts)

joints with cone rings - terminal joints - profile joints

APM Joint calculations

The criteria for the threaded joints calculation is the absence of the shearing and the absence of the opening of the conjugate surfaces, as well as the static strength and the fatigue strength; welded seams are calculated for the static and the fatigue strength; riveted joints are checked for the strength under the constant load.

  APM Joint calculations

Either absence of the shearing and non-opening or the static and the fatigue strength of the joint elements or both the former and the latter can be used(depending on the type of the joint) as a criteria for the joints of therotating elements.

It is possible to create the designed models bothin APM Joint editor and in other graphics systems, which support export to*.dxf.

Besidescalculation facilities APM Joint provides user with the functionally completeintegrated environment that includes:

specializedgraphical editor

versatile toolsfor calculation results presentation

editable built-in data base - dxf files import functionality

Completeintegrated environment

APM Joint allows to perform all types of the design and checking calculations. The formerincludes determination of the joint dimensions for the given loading, the latter— the safety factors calculation.

SCEW APM - calculation module imperfect helical gears (sliding, ball-screw and planetary)

Apm Screw

APM Screw  is comprehensive software for calculation of screw gears. It allows you to perform a complex analysis of the screw gears, compute its main performances, and select the optimum parameters of gear elements.

APM Screw - Screw gears are used for transformation of rotational movement of the screw to the transactional movement of the nut. They are widely applied in the machine tool industry, aircraft industry, roboto technics and many other areas of the modern mechanical engineering. Mean while, the existing methods of screw gear calculation collide with number of the serious problems.

APM Screw is a comprehensive software for calculation of screw gears. It allows you to performa complex analysis of the screw gears, compute its main performances, and select the optimum parameters of gear elements. The most widely used types of the screw gear

In the APM Screw you can calculate the most widely used types of screw gears. For the ball screw gears two sub types can be calculated — with one nut and with two half nuts (the latter allows the preload use). The theory of the non-ideal contact—the basis of the APM Screw. The main advantage of the APM Screw is that it allows considering the influence of manufacturing errors on the screw gear performances. It becomes possible due to the new theory of non-ideal contact, developed in the Research and Software Development Center APM Ltd. This theory is applicable to the wide range of machine elements, such as bearings, screw gears, plain joints, rolling contact guides,etc. It allows you to get reliable values of the contact displacements,stiffness, stresses and all parameters that are depended on the formers, such as longevity, moment of friction, loss of power, etc.

For the moment of friction and loss of power a list of 100 values is calculated, so you can determine the features of the distribution of these parameters. The results can be presented either as tables, as histograms or as graphs. The heat release is an integral parameter characterizing the amount of the heat released in the gear due to the friction during a time period of one hour. An arbitrary loading conditions including the preload

Calculations in the APM Screw can be made for any combination of axial and radial forces,over turning the moment and the preload allowed for a screw gear of the given type. External loads by longevity calculation can be considered to be variable in time. There is a special graph editor for that purpose.

CAM APM - calculation module and design cam mechanisms

APM Cam  is intended for cam mechanism calculation and design.

APM Cam

Cam mechanism isthe elementary mechanism that is used to transform rotational movement to translation or hobbing motion of pusher. The pusher motion law of cam mechanismis defined by cam geometry and pusher type. Cams are frequently used as controlunit providing required motion low.

APM Cam is intended for cam mechanism calculation and design.

Main Features Cam design

Function law defined by displacement, velocity, acceleration;

Working drawing generation.

The following types of cams mechanisms can be designed

  • cam mechanism with roller arm - cam mechanism with flat arm;
  • cam mechanism with roller rocker - cam mechanism with flat rocker.  

Initial data

Motion law can be defined as -  displacement graph -  velocity graph

graph of acceleration by rotation angle of cam.

To design cam mechanism you need to specify cam type, motion law, some geometry parameters of cam and material properties.

 The universal function editor is used to enter motion law function that can consist of several segments represented as linear segments, splines or any their combination. The function law can be defined as analytic function as well.

Calculation criteria - Cam profile is calculated based on pusher motion law, diameter — based on pressure angle limitation, and pusher width and radius — based on maximum contact stress.

Calculation results - APM Cam let cancalculate the following characteristics of cam - cam profile both in Cartesian and polar coordinates - angle of pressure - coordinates of the  internal and external envelopings of central profile (for cam with rollers) - animation of cam behavior - create working drawing = Working drawing generation

With APM Cam you can generate the working drawings of the cam profile in the APM Graph file format. Further it can be exported in DXF file by user request. APM Cam allows you to change the geometrical parameters of the cam, motion law, and analyze the graph of speed and acceleration. On the basis of this information you can draw a conclusion about correctness of this cam decision.
