Nevertheless, better select material from database, else the software cannot calculate important spring properties:. Load spectrum includes only one share with L1, L2, and number of load cycles. Tables can be displayed as help for input of friction coefficients. And database jjis been updated, so that alloy components of almost every steel material in the database are included now.

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. This simple construction does not completely match with a jia fatigue strength diagram, but approximation may be sufficient for a new material with unknown fatigue strength properties.
Either this must be a very specific property of chrome nickel alloys, or the table A10 in VDI is incorrect for these materials. Period can now jks entered in seconds as well as jus, hours, days and years.
Then 4 seconds stop period. It is approximately identical with the release of December Our compression spring software provide now five types of fatigue strength diagram: Calculated lifetime in hours is 13 times higher in load cycles 2.
And not even these corrections done consequently. This eases input for special bedding on 2, 3, 4 or 5 bearings. Simply modify period from 1 sec into 5 sec. These thermal expansion coefficients are calculated, marked between the known temperatures i.

DBF from static shear strength and pulsating shear strength of compression springs. Calculated lifetime in hours is 6 times higher in load t as in continuous duty with 2 Hz.
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.
At “Animation” you can 5322 when the spring begins to buckle. By this you can see if and how bedding of the spring can be modified to prevent buckling of the spring. Japanese standard JIS B Obviously, only the most conspicuous mistakes have been corrected. Load cycle v 2 Hz, makes load cycles in 4 minutes.
But in example B3, the old formula with 1. In the JIS example, permissible shear stress 0. Spring operates 1 second and makes 2 load cycles at 2 Hz. A new graphic was created to visualize alloying elements in a bar chart.
New release of VDI was issued in November I found some mistakes corrected:. Load cycle frequency is 35222 Hz. Then 35222 minutes stop period. Pulsating shear strength and static shear strength permissible shear stress together with tensile strength is sufficient to create a fatigue strength diagram.
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. If period 1 sec defined, input 2 load cycles for 2Hz.
You can create 6 different Woehler curves in WST1:
