Stress

The seek analytic thinking of a imple suspension schema of car is through in this over brood which not only provides the lector with the accent calculations but also gives an brainstorm of how proper stress abstract of real life problem can be done by using bare(a) engineering formulas and techniques. Only one member of fuck assembly is analyzed in ANSYS and the results were really promising. Acknowledgement- We are appreciative to Dr. Khalid Rehman for teaching us so well that we were able to do the stress analysis of a real life problem.Without his teachings nothing in this report could be done. We are thankful for his time and help which he unendingly gave during time of any confusion or problem. 1 . Introduction 2 2. Problem 33. CAD Model Statement 34. Manual Solution 7 4. 1.

Conc lusion 25 1.Introduction- The deciding maltreat that passes every departmenticular design is its stress analysis which gives the designer an insight that particular design would work or not, whether or not the esign is workable for fabrication or further improvements are required. Stress analysis of any design not only includes the basic 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 to a faultl like ANSYS etc.The results obtained from two solutions should contradict each other but there is always variation 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 various 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 resul ts were really promising. The report includes force and stress analysis, failure analysis and deformation calculations.The report not only provides the contributor 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 deterrent example- The first step of any design is to top its CAD model which in our case is done by using CREO VI . 0. The Cad models are shown 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.

The component part can be used as either a vapid instalment (plane stress, plane strain or infer plane strain) or an axisymmetric element. It is defined by 4 nodes having two degrees of liberty at each node translations in the nodal x and y directions. The element has plasticity, hyperelasticity, stress stiffening, large deflection, and large strain capabilities.It also has mixed face capability for simulating deformations of nearly incompressible elastoplastic materials, and fully incompressible hyperelastic materials. 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 planetary directions. Element loads are described in Node and Element Loads. hauls may be input as surface loads on the element faces as shown by the circled numbers on Figure 182. 1 . confident(p) pressures act into the element. 5. 1. 4.For triangular elements where the or enhanced strain formulations are pecified, degenerated haoma functions and a conventional integration scheme are used. 5. 2.

Some people may set out more aggressive and others may find that directs of arousal are increased. upheaval or sus pense can lead to strain. If this is happens before taking part in the activity it can result in tightness in the muscles which then could have a physical effect. Anxiety can make you feel uneasy and apprehensive both before and during our performance.When you are too anxious you can make mistakes. Some find some level of anxiety necessary to focus and prepare. Nervousness can add to your tension levels, making you feel more tense and even agitated to the straits where a physical effect can take place e. G being sick or shaking. Motivation will almost for certain decrease Nearly everyone who has taken part in a physical activity has experienced some type of stress. Stress is more gross when the focus is on one person.Stress
