Piano wires JIS G 3522 SWPB

Spring operates 1 second and makes 2 load cycles at 2 Hz. Database with international material names was extended by material names according to Chinese and Indian Standard, and by ISO material 3252 as well.

Self-defined material data are saved together with the spring dimensions. According to JIS, horizontal limit line depends on permissible setting of the spring and may be higher or lower as 0. Therefore, load cycle frequency is no longer printed in the production drawing for this case.

Same as previous example, but spring is not operated in continuous duty. And database has been updated, so that alloy components of almost every steel material in the database are included now.

It is approximately identical with the release of December But in example B3, the old formula with 1. In equationthe “mzu” for reduced thread length by chamfers was changed from 1.

New Quick4 View includes material properties and diagrams in an ISO drawing frame on one screen. At “Animation” you can watch when the spring begins to buckle. Nevertheless, better select material from database, else the software cannot calculate important spring properties:.

HEXAGON Info No.

Simply modify period from 1 sec into 5 sec. Calculated lifetime in hours is 13 times higher in load cycles 2. Period can now be entered in seconds 35222 well as minutes, hours, days and years. Calculation with and without load spectrum must lead to equal results.

Tables can be displayed as help for input of friction coefficients. Load spectrum includes only one share with L1, L2, and number of load cycles. 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.

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. A new graphic was created to visualize alloying elements in a bar chart. Jid this you can see if and how bedding of the spring can be modified to prevent buckling of the spring. Changes are not described. New release of VDI was issued in November In the JIS example, permissible shear stress 0.

This eases input for special bedding on 2, 3, 4 or 5 bearings.

DBF from static shear strength and pulsating shear strength of compression springs. And also for 2. I found some mistakes corrected:. Pulsating shear strength and static shear strength permissible shear stress together with tensile strength is sufficient to create a fatigue strength diagram.

These thermal expansion coefficients are calculated, kis between the known temperatures i.

Either this must be a very specific property of chrome nickel alloys, or the table 322 in VDI is incorrect for these materials. And not even these corrections done consequently. Calculated lifetime in hours is now 5 times higher than in continuous duty. If period 1 sec defined, input 2 load cycles for 2Hz. Load cycle frequency is 2 Hz.
