I'm working about torsional vibration , I use a pic-upin front of flywheel : what is the relation between : angolar resolution , number of teeth , sample rate ... thanks in advance

hi , in this period I have many problems because whine pump noise . How can reduce the ripple around the mean prssure (30 bar)? Do you know where I can find papers about it ? Can I act also insuction side ? I am thinking about cavitation problems The pump is whith inner rotors . thanks in...

I acquire force signal on engine mounts in car during a long durability standard-test on the road(ex.: 30000 km). Next step I have play a drive file on test rig an equivalent test (ex.:1000000 cycles on test rig like 30000 km on car). Who daes know anything about rain-flow data processing or any...

Does anyone know a formula where : I have a vector "c" that forms angle "alfa" with "a" direction and angle "beta" : Does someyone know a formula in order to have vector (c)components on two direction (a e b) known the angles "alfa" e "beta" ? Thanks molossi74

Hi to everyone : I'm finding some paper about suspensions filtering for comfort. My problem is to find a relation between bushing stifness and body stiffness (local inertance of a shock tower with 4 attach points ...) Can I make a body less stiff if I use a bushing less stiff ? bye

Does someone know a method or mathematica formula to balance a shaft without using a phase probe ...but just trial masses? Many thanks ! Molossi74

I need metrial / paper about trasfer path analysis ! who can help me ? thanks to everyone Molossi74

hi to averyone ! How can I reduce vibration from exhaust system without reduce torque and power ? Does anyone know any formulas / materials about resonances of exhuast and pipelines system ? Many thanks
