Stress

The attempt abstract of a imple suspension system of car is d iodine in this deal which not exactly provides the reader with the stress calculations but also gives an insight of how proper stress outline of real purport problem can be done by use simple engineer formulas and techniques. Only one member of complete assembly is analyzed in ANSYS and the results were really promising. Acknowledgement- We ar thankful to Dr. Khalid Rehman for teaching method us so well that we were able to do the stress analysis of a real liveness problem.Without his teachings nothing in this report could be done. We are thankful for his time and help which he everlastingly gave during time of any confusion or problem. 1 . Introduction 2 2. Problem 33. detent place Statement 34. Manual Solution 7 4. 1.

Conclusion 25 1.Introduction- The deciding mistreat that passes any particular design is its stress analysis which gives the designer an insight that particular design would work or not, whether or not the esign is feasible for lie or further improvements are required. Stress analysis of any design not only includes the primary force and stress calculation in members but also the failure, deformation analysis of the complete assembly. Stress analysis can be done manually or by using any CAD tool like ANSYS etc.The results obtained from both solutions should match each other(a) but there is always genetic mutation in the results. The variations can be due to ideal approximations in the manual calculations or any other assumed data. The report includes the stress analysis of a imple suspension system of a car confused assumptions are being made which are mentioned in respective sections of the report. The solution was done both manually and by using ANSYS and the results were really promising. The report includes force and stress analysis, failure analysis and deformation calculations.The report not only provides the reader with the stress calculations but also gives an insight of how proper stress analysis of real life problem can be done by using simple engineering formulas and techniques. Stress analysis of a simple suspension system of car. 3. CAD model- The first step of any design is to make its CAD model which in our case is done by using CREO VI . 0. The Cad models are maken as follows (Fig 3. 1 complete assembly) (Fig 3. 2 complete assembly) The above fgures show the cad model of whole assembly. The individual member models are also shown below (Fig 3. 4 Hub) (Fig 3. 5 Connecting arm) (Fig 3. 6 spring) (Fig 3. Suspension arm) 5. ANSYS 5. 1.

Element Description PLANE182 is used f or 2-D modeling of solid structures. The instalment can be used as either a plane element (plane stress, plane strain or generalized plane strain) or an axisymmetric element. It is defined by four nodes having twain degrees of freedom at each node translations in the nodal x and y directions. The element has plasticity, hyperelasticity, stress stiffening, coarse deflection, and large strain capabilities.It also has mixed formulation capability for simulating deformations of nearly incompressible elastoplastic substantials, and fully incompressible hyperelastic stuffs. The geometry and node locations for this element are shown in Figure 182. 1. The element input data includes four nodes and the orthotropic material properties. The default element coordinate system is along global directions. Element loads are exposit in Node and Element Loads. Pressures may be input as surface loads on the element faces as shown by the circled numbers on Figure 182. 1. Positive pressures act i nto the element. 5. 1. 4.For triangular elements where the or enhanced strain formulations are pecified, degenerated shape functions and a conventional integration scheme are used. 5. 2.

Some people may become more aggressive and others may find that levels of arousal are increased. Excitement or suspense can lead to tension. If this is happens before taking part in the practise it can result in tightness in the muscles which then could have a physical effect. anguish can make you feel uneasy and apprehensive both before and during our performance.When you are too importunate you can make mistakes. Some find some level of anxiety necessary to focus and prepare. nerves can add to your tension levels, making you feel more tense and even agitated to the lay where a physical effect can take place e. G being sick or shaking. Motivation will almost certainly decrease Nearly everyone who has taken part in a physical activity has experienced some type of stress. Stress is more common when the focus is on one person.Stress
