Five facts about rub­ber-to-met­al ele­ments

you should consider

If rub­ber-met­al ele­ments are to car­ry large loads, for exam­ple, in addi­tion to the com­po­nent geom­e­try, the weight dis­tri­b­u­tion / cen­ter of grav­i­ty of the sys­tem is also of great impor­tance. This is the case, for exam­ple, with machine feet. In addi­tion to the com­po­nent geom­e­try and hard­ness, which are deci­sive for the stiff­ness of the bear­ing, the instal­la­tion sit­u­a­tion of the bear­ings and the geom­e­try of the machine also play an impor­tant role in terms of sta­t­ic load and dynam­ic per­for­mance. If the cen­ter of grav­i­ty is exact­ly in the mid­dle, all pedestals are equal­ly loaded. How­ev­er, if the machine is designed asym­met­ri­cal­ly, the load is dis­trib­uted uneven­ly. As a result, indi­vid­ual machine feet are exposed to high­er sta­t­ic and dynam­ic loads than oth­ers. If this cir­cum­stance is not tak­en into account in the design and lay­out of the bear­ings, these com­po­nents can fail in use after a short peri­od of oper­a­tion, which can cause fur­ther dam­age to the machine.

There­fore, cer­tain input vari­ables should be con­sid­ered when design­ing rub­ber-to-met­al ele­ments.
The sta­t­ic load dis­tri­b­u­tion, as well as fur­ther para­me­ters (e.g. fre­quen­cies, ampli­tudes, etc.), are impor­tant input vari­ables, because the over­all per­for­mance depends on them, pro­vid­ed that the com­po­nent is designed correctly.
