Nominal stress:

σnom = F/(w-d)t= 2000/(40-10) = 66.666 N/mm2

Stress concentration:

Kt = σmax/ σnom

COLLABRATIVE WORKING IN A MULTI-USER ENVIRONMENT

Working in a multi-user environment is a challenging and error-prone task in an engineering sector. SOLIDWORKS has options and tools to perform tasks in a multi-user environment to a great extent in an easy manner. But it is important to setup a systematic multi-user environment.

Setting a Multi-user Environment:
The first step for a multi-user system is assigning defined tasks for each and every person & maintaining separate level for work flow.
1) Manager : Scheduling the task & Instructing the required changes
2) Supervisors / Leaders : Check the data and assigning & coordinating the work
3) Bottom level workers / Designers : Will perform the assigned work (Designing)

File Storage:
The most important task is to keep data files in a centralized server or system. It should contain only read-only access to avoid accidental changes in data files.

It is difficult to work together if the files are stored in the local hard drives, especially in SOLIDWORKS. Hence proper Implementation plan is required for seamless work-flow.

File Transfer:
Supervisors / Leaders should take care of the file transfer (in & out) and he is provided with administrative access to the data files.

Task Management:
Manager will schedule the task to the concern person and monitor the individual as well as team updates. Even simple mistakes can cause major problems.

SOLIDWORKS Options:
In SOLIDWORKS, following settings are available for collaborative working.

Tools --> Options --> System Options --> External Reference
Tools --> Options --> System Options --> Collaboration

These options control the file permissions within the team and help to work in the most recent or updated files by every users.

External Reference:
In this section, the first option will be “Open referenced documents with read-only access”. This option must be checked when two or more users are working in the same directory.

When this option is checked all referenced documents related to the assembly will be opened only with the read-only access by default.



Collaboration:

This entire section is dedicated to multi-user settings. Checking “Enable multi-user environment” option changes the work-flow from single user to multi-user by activating the other options of the collaboration section.









If “Add shortcut to menu items for multi-user environment” is checked, a shortcut is added to file menu list as Get Write Access / Make Read-only. This will help the multi-users to work on a single document (part or assembly) and make changes accordingly without any error.





















Check if files opened read-only have been modified by other users” option is to check the whether the opened read-only file have been modified or saved by other user for the interval specified by the current user. (Note: Lightweight components are not checked)

If the system detects a change, a tool-tip in the lower right of the graphics area points to an icon on the status bar. Click the icon to access the Reload dialog box. Reload dialog is used by the current user to reload or update the modifications done by the other users.



This section also contains options related to comments which can be useful for communicating the changes required and necessary details between the various users with time-stamp added to the comments in the multi-user environment.


 






Design Optimization Using SOLIDWORKS Configuration Publisher

Configuration Publisher provide a solution for design optimization. It is used to create
custom Property Manager for selecting configurations of parts and assemblies.
Configuration Publisher is placed in the property manager. Use the Property Manager
when adding a component to an assembly in SOLIDWORKS or when downloading a
model from 3D Content Central. To work with configuration Publisher, Microsoft Excel must
be installed on our system.

Configuration Publisher to control the ranges of features in the part to optimized
automatically in the design table. The Configuration Publisher dialog box, you can able to
create an interface for specifying configurations of parts and assemblies. It will use the
interface of SOLIDWORKS and 3DContentCentral.

1. Right click the top of the feature manager design tree and select the Configuration
Publisher as in Fig 1.





















2. If you not create design table,The Configure Publisher to auto-create the design
table.click “Yes” In the confirm auto-create window as in Fig 2.
3. After click the “yes” tab to automatically open the dimension window,select the
dimensions to make the design table.





















4. The Configuration Publisher box will then come up showing the different properties
(control box) that can be used to filter through the configurations. You set attributes for
each control in the available options vary depending on the control type and creation of
model variants.



It’s very useful to control over the Dimensions, Materials, Suppression states,etc. You
can drag the list box controls from the left in to middle to use, while the middle section the
edit tab is selected.
5. Selecting control boxes in the middle automatically open the attribute tab in the same
window right side. It allows to editing its properties on the attributes tab.



6. After editing is completed, click Apply for the changes to be reflect on to the model. Also
can share our mofidified model to web with the help of Upload to 3D Content Central.



7. When opening part file in assembly, configure component tab will open automatically
and set your input values.



Benefits:

  • The configure Publisher which is used to Controlling part configurations, exploring design tables, creating a design table.
  • This improves flexibility and lets you create more configurations.
  • Create configurations and share them by automatically uploading your designs to 3D Content Central.
  • It is used to reduce the time of the changes in the model designing.
