Then 48 minutes stop period. DBF from static shear strength and pulsating shear strength of compression springs. Our compression spring software provide now five types of fatigue strength diagram: Then 35222 seconds stop period. Obviously, only the most conspicuous mistakes have been corrected. Room licenses for education are no longer unlimited to any computer in one room, but limited to simultaneous access to maximal 20 workstations in a room. Calculation with and without load spectrum must lead to equal results.

Min and max values of the alloy components are drawn in a logarithmic scale so that even small shares are visible.

By this you can see if and how bedding of the spring can be modified to prevent buckling of the spring. This jia input for special bedding on 2, 3, 4 or 5 bearings.

Either this must be a very specific property of chrome nickel alloys, or the table A10 in VDI is incorrect for these materials. Database with international material names was extended by material names according to Chinese and Indian Standard, and by ISO material names as 3522. Calculated lifetime in hours is 13 times higher in load cycles 2.

New release of VDI was issued in November Simply modify period from 1 sec into 5 sec. And also for 2. Tables can be displayed kis help for input of friction coefficients.

These thermal expansion coefficients are calculated, marked between the known temperatures i. It is approximately identical with the release 322 December Self-defined material data are saved together with the spring dimensions.

Info No. 154 – Nov./Dec. 2015

According to JIS, horizontal limit line depends on permissible setting of the spring and may be higher or lower as 0. Calculated lifetime in hours is 6 times higher in load spectrum as in continuous duty with 2 Hz. Shortcuts for Quick view were unified for all programs to show Quick View by means of key combination Alt-V iew and then 1,2,3,4 for Quick1,2,3,4 View. Nevertheless, better select material from database, else the software cannot calculate important spring properties:.

I found some mistakes corrected:. Load cycle frequency is 2 Hz. You can create 6 different Woehler curves in WST1: In the JIS example, permissible shear stress 0. And database has been updated, so that alloy components of almost every steel material in the database are included now.

But in example B3, the old formula with 1. And not even these corrections done consequently. Therefore, load cycle frequency is no longer printed in the production drawing for this case. If ISO title block with 10 mm sheet border was configured, some tables in A4 production drawings are now compressed so that drawing content no longer interfere with 10 mm border.


This simple construction does not completely match with a measured fatigue strength diagram, but approximation may be sufficient for a new material with unknown fatigue strength properties. Spring operates 1 second and makes 2 load cycles at 2 Hz.


At “Animation” you can watch when the spring begins to buckle. Same as previous example, but spring is not operated in continuous duty. Pulsating shear strength and static shear strength permissible shear stress together with tensile strength is sufficient to create a fatigue strength diagram.

If period 1 sec defined, input 2 load cycles for 2Hz. A new graphic was created to visualize alloying elements in a bar chart. In equationthe “mzu” for reduced thread length by chamfers was changed from 1. Period can now be entered in seconds as well as minutes, ji, days and years.

Changes are not described. Calculated lifetime in hours is now 5 times higher than in continuous duty. New Quick4 View includes material properties and diagrams in an ISO drawing frame on one screen.

Japanese standard JIS B Load spectrum includes only one share with L1, L2, and number of load cycles. Load cycle frequency 2 Hz, makes load cycles in 4 minutes.
