Finding rollcenter and instant center

 front and rear assembly images  after tuning hardpoints, the next step is to maintain constraints  1. according to hardpoints hand calculations were done to achieve the value of the constraints  2. after fixing  values I imported front and rear hardpoints into CATIA to get other results which…

1.0 Here's a list of various types of aircraft and their approximate weight ranges, divided into several categories. Please note that the weights mentioned are approximate and can vary depending on the specific model and configuration of the aircraft. Light Sport Aircraft (LSA): Cessna 162 Skycatcher: 830 kg (1,830 lbs)…

  1.0 Speed control of a DC motor using BJT H-bridge' demonstrates how to control the speed of a DC motor by adjusting the voltage applied to the motor using a bipolar junction transistor (BJT) H-bridge. The model includes the following key components: Step input: Represents the desired motor speed reference signal.…

1.0 I have considered a drive cycle from the net and considered 4 different cases of braking condition of the cycle and calculate each case brake energy and sum up to get the final brake energy. To calculate the braking energy for each situation, we can use the formula:   E_braking = 0.5 * Mt * (Vi^2 - Vf^2), where…

Renderer Type The type of renderer used: Raycaster, Raytracer, Hidden Line, Powercaster, or Powertracer. The icon in the Rendering Options window changes if you change Renderer Type. If Renderer Type is Powercaster or Powertracer, the Processors parameter becomes available. The default setting is Raycaster. Note: With…

Introduction to Class-A Class-A (or 'Strak') is a term used in specifically in automotive design. It describes the final production surface data for the aesthetic parts of the car. The term 'Class A' is often misunderstood, but it's generally seen as the 'Holy Grail' of surface modeling. This is because as it achieves…

Torus Options Sweep The degrees of rotation around the center of radial primitives. For example, if you enter 180 degrees in the sphere tool, Alias creates a hemisphere. Size Size can be either Absolute or Relative, and determines which of the following parameters can be set. Major radius…

Align surface edges This aligns one surface to one or more surface edges, trimmed edges, curves, curves-on-surface, or isoparametric curves. Choose Object Edit > Align > Align  . Edge is the default Alignment Type. Click the edge of the surface you want to align (the Input). Sequentially…

Underbody coating is usually a dense cladding (often based on rubber) applied uniformly to the undercarriage of the automobile. It is normally sprayed or painted on when the car is just out of the dealership and is clean. But even if you are getting the undercoating applied after a couple of years, it’s fine too.…

What all can be studied from the BiW of a competitor? Before we jump on to the details of the alternate approach to benchmark BiW in the least time at the least cost, shown below is the list of individual studies that can be conducted on Body In White to extract information that can be used as engineering intelligence…

                                                                 horizontal and vertical master sections are important to create housing so I have created these master sections with the help of lens and hot-plate section assembly and offset them and trim them to get housing section shape.

Suspension assembly in Adams: to achieve my targets I imported hardpoints from Adams to CATIA and with the help of line diagrams, I fixed my hardpoints according to the targets.  after giving constraints I changed my hardpoints in Adams  Caster angle is the angle in the side elevation (vehicle XZ plane) between…

part 2: tuning of the rear suspension system  To get bump steer for the rear multilink suspension first I have taken the hardpoints into CATIA   depending upon this hardpoints I have changed lower linkage points until I reached my target dumpster of 2.6 deg/m  for every change of hardpoints, I have…

caster angle is achived with the help of hardpoints as given 5.37degree negative caster mechanical trail is the distance between the steering axis and the center of tire measured longitudinally on the ground achived mechanical trail of 9.4mm kingpin inclination =10.004degree positive scrub raidus=32mm spindle length it…

this is my postprocessor graphs of camber_caster_toe_scrub of double wishbone suspensions and i identified them wih different types of lines and colours as you can see and line at center indicates the static values  next i had animatedin in postprocessor suspension ansys of parallel wheel travel

according to baja event i designed our vehicle front double wishbone suspension  so after assembly of our vehicle we get cog from that we place our roll center height near to it in catia and imported those hard points in to adams and i stimulated it and got 

1) according to the formula wheel_rate=fw/delta`delta`x  so force per displacement over the wheel spring_rate = fs/delta`delta`y so force per displacement over spring  where ``kw`=`ks`x`mr^2` so wheel rate and spring rate are almost equal but in wheel rate consider only wheel while in spring rate consider…

 1. compliance it is used to know how much deflection suspension makes under braking ,longitudinal forces and vertical forces ,lateral forces there are several types in order to reduce or used this complaince like bushing , soft mounting etc...this type of bushing is used to get desired steering characteristics under…

anti-squat 1. yes we can completely prevent the rear suspension from extension by using anti dive and squat concept we if put an effort to achive 100% of during braking and accerlation the load will transfers is resisted by the suspensions arms and no force acts on springs and the forces are controlled by pivot points …

You didn\'t mention clearly from where we have to take y coordinates like spindle length so I have taken from center of the wheel like half the track width 800mm Instant center :  from center of the wheel i have taken y coordinates so I get in negative direction towards left from center of the vehicle -ve y :1450mm…

1. Camber gain  The weight get shifts to the outside of the vehicle while going under cornering so vehicle rolls outside of the turn because of tire contact the road so because of this reason we need camber gain principle so that it make tire to get more grip during cornering and in break test also antidive antisquat…

1  Degree of freedom : it is a defined mode in which the system move suppose in suspension system like double wish bone we have five links so degree of freedom is five simply the the individual bodies moves in 5direction to complete  motion of the body 2. Ball joint : it has 3 degree of freedom 3. Yesit is necessary…

 virtual swing arm : it is length of arms from the body which is mounted  to the kunckle  Virtual pivot :it is the point where upper armand lower arms gets contact if we drawn an imaginary line of both the arms that point is called virtual pivot  Roll centre : from the centre of the wheel contact to…
