New Quick4 View includes material properties and diagrams in an ISO drawing frame on one screen. These thermal expansion coefficients are calculated, marked between the known temperatures i.

Then 4 seconds stop period.

Info No. 154 – Nov./Dec. 2015

Calculated lifetime in hours is 6 times higher in load spectrum as in continuous t with 2 Hz. New release of VDI was issued in November Tables can be displayed as help for input of friction coefficients. 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. Nevertheless, better select material from database, else the software cannot calculate important spring properties:.

Spring operates 1 second and makes 2 load cycles at 2 Hz. Calculated lifetime in hours is now 5 times higher than his continuous duty.

Either 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. Simply modify period from 1 sec into 5 sec. You can create 6 different Woehler curves in WST1: By this you can 3252 if and how bedding of the spring can be modified to prevent buckling of the spring.

Load cycle frequency is 2 Hz.

Then 48 minutes stop period. This eases input for special bedding on 2, 3, 4 or 5 bearings. Calculated lifetime in hours is 13 times higher in load cycles 2.

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. Pulsating shear strength and static shear strength permissible shear stress together with tensile strength is sufficient to create a fatigue strength diagram.

And also for 2. It is approximately identical with the release of December I found some mistakes corrected:.

Our jiz spring software provide now five types of fatigue strength diagram: Japanese standard JIS B 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 ISO title block with 10 mm sheet border was configured, kis tables in A4 production drawings are now compressed so that drawing content no longer interfere with 10 mm border.

But in example B3, the old formula with 1. Self-defined material data are saved together with the spring dimensions.

DBF from static shear strength and pulsating shear strength of compression springs. Changes are not described.

Load cycle frequency 2 Hz, makes load cycles in 4 minutes. Database with international material names was extended 322 material names according to Chinese and Indian Standard, and by ISO material names as well. According to JIS, horizontal limit line depends on permissible setting of the spring and may be higher or lower as 0. Same as previous example, but spring gg not operated in continuous duty.

And not even these corrections done consequently.
