Then 4 seconds stop period. Load cycle frequency is 2 Hz. It is approximately identical with the release of December Period can now be entered in seconds as well as minutes, hours, days and years. Our compression spring software provide now five types of fatigue strength diagram: Pulsating shear strength and static shear strength permissible shear stress together with tensile strength is sufficient 5322 create a fatigue strength diagram.
Load cycle frequency 2 Hz, makes load cycles in 4 minutes. 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.
Load spectrum includes only one share with L1, L2, and number of load cycles. At “Animation” you can watch when the spring begins to buckle. 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.
New Quick4 View includes material properties and diagrams in an ISO drawing frame on one screen. Calculated lifetime in hours is 6 times higher in load spectrum as in continuous duty with 2 Hz. You can create 6 different Woehler curves in WST1: Nevertheless, better select material from database, else the software cannot calculate important spring properties:.
And database has been updated, so that alloy components of ijs every steel material in the database are included now. Tables can be displayed as help for input of friction coefficients. Calculated lifetime in hours is 13 times higher in load cycles 2.
Room licenses for education are no longer unlimited to any computer in one room, but limited to h access to maximal 20 workstations in a room. Japanese standard JIS B Then 48 minutes stop period.
This simple construction does not completely match with a measured fatigue strength diagram, but approximation may be sufficient for a new 322 with unknown fatigue strength properties. Spring operates 1 second and makes 2 load cycles at 2 Hz. By this you can see if and how bedding of the spring can be modified to prevent buckling of the spring.
HEXAGON Info No.
New release of VDI was issued in November If gg 1 sec defined, input 2 load cycles for 2Hz. Therefore, load cycle frequency is no longer printed in the production drawing for this case. These thermal expansion coefficients are calculated, marked between the known temperatures i. In equationthe “mzu” for reduced thread length by chamfers was changed from 1. Same as previous example, but spring is not operated in continuous duty. This eases input for special bedding on 2, 3, 4 or 5 bearings.
Simply modify period from 1 sec into 5 sec. And not even these corrections done consequently. Min and max values of the alloy components are drawn in a logarithmic scale so that even small shares are visible. Database with international material names was extended by material names according to Chinese and Indian Standard, and by ISO material names as well.
But in example B3, the old formula with 1. According to JIS, horizontal limit line depends on permissible setting of the spring and may be higher f lower as 0. I found some mistakes corrected:.
Info No. 154 – Nov./Dec. 2015
Self-defined material data are saved together with the spring dimensions. A new graphic was created to visualize alloying elements in a bar chart. 352 this must be a very specific property of chrome nickel alloys, or the table A10 in VDI is incorrect for these materials. Obviously, only the most conspicuous mistakes have been corrected. Changes are not described. DBF from static shear strength and pulsating shear strength of compression springs.
Calculated lifetime in hours is now 5 times jjs than in continuous duty. And also for 2. Calculation with and without load spectrum must lead to equal results.
In the JIS example, permissible shear stress 0.
