Bushido (Miyamoto Musashi) 1

Bushido (Miyamoto Musashi)
he was famous for 2 sward fighter in Edo period
he wrote a book named Gorinsho which is aimed for war tactics .
he never failed in fight in his life .
Gorinsho is consist of earth water,fire,wind,sky.

CAE

CAE
this is abbreviation of Computer  Aided Engineering
CAD is computer aided designing .By CAD all pars and forms  is designed 3D computer
modeling software.
3 D modelling is most popular for designing engineering parts bolt and nut ,press parts
plastic parts for industry of automobiles,aircraft and electric appliance.
this CAD is essential for technology. CAE is simulation software from 3D modeling .
all prats is consist of spring and damper with weight with leads to natural frequency.

How is relation time domainan /frequncy domain and mix juce.

How is relation between time domain an /frequency domain and mix juice.
Regarding mix juice how much it is contains totally.
Volume of mix juice is 200ml .
but what kind s of contain such as banana and apple and strawberry and so on.
answer is banana is 100 ml and applies 50ml and strawberry is 50ml totaling to 200ml.
for time domain how much is included totally but we cannot see what kinds of
frequency is involved .for example in time domain , oscilloscope , we can see how much
frequency totally.by oscilloscope.from time domain totally 1300 Hz and FFT show you what kind  of frequency is included such 100hz and 200Hz and 1Khz and t totaling 1300Hz.as same as it is mix juice we of our technology is seeking the volume and kinds.
our solution int technical innovation we try to search volume and kinds.
that's is key word.

Modeling

Modeling
We leads to natural frequency from time domain to frequency domain.
all material is composed  of spring and damper with the weight.
weighed is mass cancelling by computer calculations.
some parts 3D automobile for example will be made by 3D modeling .
Shape  of parts is calculates into and be led to  value of natural frequency in all points.

modeling is CAD computer added designing

Our natural frequency, oposite meaning

Our natural frequency oposite meaning we have a natural frequency.I said that natural frequncy is uniqu only one in the world. you are only one int he world. if you like someone ,for example, your natural frequency is 100 Hz, but someone you like to is 50Hz. if both is 100Hz is what we call ,resonance.may be, you love each other in the same Hz..if your lover is 50Hz it is hard to be together .if soneone is thinking bad thing your friend come closs to you. what we call ,simpathic vibration but please keepit mind resonance and simpathic viration is same conception ,good thing is resonace on nthe other hand , it is bud meaning .if you are driving a car car is made of steel plate and bolts and nuts .your speed arisees thimpathy vibration it may happen the bolts is same frequency 50HZ your spped vibarion is 50Hz your bolts and nuts may come looth in dagerouse case ,that is covibration.or vibratting together it has a risk to happen a lelease of bolt and nuts in a car. engineer of car industry is seeking the covibration rate and they will desine the car to keep away from covibration like a happning of bolts and nuts release.cobibration and is they seek the natural frequency. Resonance and cobibration is same meaning ,but if situatinis changed the wors is changed to opsite meaning.

Relation between stifness and damper

Relation between stiffness and damper
Engineer and developer of automobile and air industry and material related company is eager to seek the material characteristic.there is spring and damper.spring is that that power is going to expand and damping is power of going to shrink .
we are on pendulum. we are like paling on seesaws. our life is on balance.
strong and softness and stiffness and damper, good or bad
something between stiffness and damper the important value is natural frequency.
we are seeking our character that is individual and personality.we are only one
which is unique in the world.

spring and damper and weight

Spring and damper and weight
all materials is consist of 3 factors
middle is weight and spring in left side and damper in right side
it is organized pendulum and swing.
spring is what it is expanding movement and damper is drinking movement in the swing
between spring and damper they are going try to the balancing in moment.
BY FFT balancing of spring and damper it will show you the individual frequency(natural frequency )in transfer function.
all material leads to the natural frequency by FFT.
Our character and personalities is form in the balance of stiffness and weakness.
Natural frequency is very important in our daily life.
