Vehicle Ride 1

Given :- Total Weight = 1900 kg F/R distribution = 55% Front Unsprung mass front = 90 kg Unsprung mass rear = 60 kg Solution :- i) a) Front sprung mass critical damping = 2 * sqrt (Kr * ms)  Front Ride rate, Kr = (Ks * Kt)/(Ks + Kt)                      = (20*250)/(20+250)…

ANTI CHARACTERISTICS- Anti-Geometry consists of anti-dive, anti-squat, anti-lift. Anti-geometry refers to the front and rear wheels that controls the amount of the travel in spring due to acceleration or braking conditions. The anti-geometry doesn't alter the amount of longitudinal load transfer that occurs in braking…

Rear multi link subsystem is opened from Acar shared, and then this saved as assembly in our private folder, and the same file is opened. and following simulation is carried out- 1. brake steer-  Brake steer= 0.06 deg/KN Brake steer= 0.16 deg/mmso the suspension toes out making the car oversteer.  2.…

A double wishbone suspension steering assembly was opened- Hardpoint modification- In order to perform kingpin geometry optimization, the first task is to run the simulation using the original hardpoints specified in the adams. Based on the initial values and there results obtained, points are changed various times to…

screenshot 54- it is the initial basic graph of camber angle vs wheel travel graph created by adams. ss 55- is page 1, where the colour of the graph is edited by selecting curve, with an added title and edited legend, The x-axis and y-axis are changed accordingly in haxis and vaxis for our requirement. ss 56 and ss 57-…

1. we open adams car. and open new subsystem and select the double wishbone template from Acar shared files. 2. We will save this file in our seperate folder we created 3.Then we select new assembly and select the double wishbone subsystem we saved in our personal folder and check mark steering system and add a steering…

1.wheel rate- The measure of effective stiffness of the suspension system measured at the wheel center.  spring rate- the amount of weight required to compress the spring one inch, and we all so know that  wheel rate = spring rate* (motion ratio)^2   2. ride rate- vertical deviation from sprung mass…
