Failure analysis,dimensional And Analysis,Applications Of Cams
Introduction
It is absolutely essential that a design engineer know how and why parts fail so that reliable
machines that require minimum maintenance can be designed.sometimes a failure can be
seriously,such as when a tire blows out on an automobile traveling at high speed.on the other
hands,a failure may be no more than a nuisance.an example is the loosening of the radiator hose
in an automobile cooling system.The consequence of this latter failure is usually the loss of some
radiator coolant,a condition that is readily detected and corrected.
The type of load a part.absorbs is just,as significant as the magnitude.generally speaking,
dynamic loads with direction reversals cause greater difficulty than static loads,and therefore,
fatigue strength must be considered.Another concern is whether the material is ductile or
brittle.for example,brittle materials are considered to be unacceptable where fatigue is involved.
Many people mistakenly interpret the word failure to mean the actual breakage of a
part.however,a design engineer must consider a broader understanding of what appreciable
deformation occur.A ductile material ,however will deform a large amount prior to
rupture .excessive deformation,without fracture,may cause a machine to fail because the
deformed part interfere with a moving second part .therefore,a part fails(even if it has not
physically broken)whenever it no longer fulfills its required function.Sometimes failure may be
due to abnormal friction or vibration between two mating parts.Failure also may be due to a
phenomenon called creep ,which is the plastic flow of a material under load at elevated
temperature.In addition ,the actual shape of a part may be responsible for failure.For example,
stress concentration due to sudden changes in contour must be taken into account.Evaluation of
stress considerations is especially important when there are dynamic loads with direction reversals
and the material is not very ductile.
In general,the design engineer must consider all possible modes of failure,which include the
following.
---------stress
---------deformation
---------wear
---------corrosion
---------vibration
---------environmental damage
---------loosening of fastening devices
The part sizes and shapes selected also must take into account many dimensional factors that
produce external load effects,such as geometric discontinuities,residual stresses due to forming
of desired contour,and the application of interference fit joint.
Cams are among the most versatile mechanisms available.An cam is simple two-member device-dependent.The input member is the cam itself,while the output member is called the follower .through the use of cams,a simple input motion can be modified into almost any
conceivable output motion that is desired.Some of the common applications of cams are
-------camshaft and distributor shaft of automotive engine
-------production machine tools
-------automatic record players
-------printing machines
-------automatic washing machines
-------automatic dishwashers

这是一篇关于机械论文的摘要,
Abstract:In a conventional one-dimensional scheme design of centrifugal fans and compresx1fsors,it is assumed that there is no flow prewhirl at the impeller inlet when the inlet guide vane is absent.However,many experiments have proved that the flow prewhirl does exist at the inlet of centrifugal impellers.This results in an error in the design of centrifugal fans and compressors.In this study a new method is presented to calculate the Euler work of centrifugal impellers conx1fsidering the presence of an inlet flow prewhirl in the case without the inlet guide vane.Stodola's approach dealing with the slip velocity at the impeller outlet is applied to the impeller inlet.A new formula for Euler work calculation is deduced to evaluate the effect of the inlet prewhirl.The new formula has been applied to 33 industrial centrifugal fans and the calculated results have been compared with the experimental data of these fans.The comparison shows that the new formula is more accurate in most cases than the original formula without consideration of the inlet flow prewhirl,and the accuracy has been improved by more than 10 per cent on average.The aim of this study is to improve the accuracy of the one-dimensional scheme design of centrifugal fans and to provide a reference for a similar research.

Abstract
A three-dimensional particle dynamic analyzer (3D-PDA) was employed to measure the gas-solid two-phase flow in a lab-scale square cyclone
separator with downward gas-exit.Several cases of different inlet velocity and particle concentration were studied.The particle used in the test
was glass bead of mean diameter 30-40 p,m.Discussion was given on the distribution of flow vector,mean velocity,turbulent intensity and kinetic
energy of both gas and particles of different diameter at different position in the separator.It was found that the center of the flow field deviated
from the geometric center of the cyclone.The flow fields had the feature of Rankine eddy,i.e.,strongly swirling region in the central part and
pseudo-free eddy region of weak swirling intensity near the cyclone wall.Local vortex existed at the corners where the flow changed its direction
sharply.When the cyclone wall was heated and the suspension temperature was elevated,the flow field became more uniform than that under
room-temperature condition.The local vortexes at the corners were weakened and the swirling intensity became poorer which led to decreased total
mean separation efficiency from about 81 % to 76.5%.The right-side wall facing the suspension inlet gave the major contribution to the separation
efficiency,where the largest downward velocity was measured.Back-flow (upward velocity) was found around the center of the separator above
the gas-exit.The quasi-laminar motion of particles enhanced the turbulent motion at the corners due to particle-particle or particle-wall collision,
which led to the local peak value of the turbulent kinetic energy and turbulent intensity.The corner was one of the major regions to cause pressure
drop and was found to be beneficial to particle separation mainly because the strong fluctuating flow consumed much of the kinetic energy of both
the particle and gas.

This learning algorithm maps the low dimensional datasets to the high dimensional feature space,and aims to solve a binary problem by searching an optimal hyperplane which can separate two datasets with the largest margin in the high dimensional space.
这种学习算法把低维数据集映射到高维特征空间,并且旨在通过搜索一个最优超平面来解决一个二进制（二元）问题,这个超平面能用高维空间最大间隔分开2个数据集.
As shown in Fig.2,the optimal hyper plane is defined by wx06x + b = 0,where x is the point lying in the hyperplane,w is the parameter for the orientation of hyperplane,and b is a scalar threshold which represents the bias from the margins
如图2（Fig2）所示,最优超平面由wx06x+ b = 0定义,其中x是超平面上的一个点,w是超平面取向（定位）参数,b是一个标量阈值,代表间隔偏差（边缘偏差）.
