Percent Anti Squat Solution

STEP 0: Pre-Calculation Summary
Formula Used
%Anti Squat = (tan(Angle between IC and Ground)/(Height of CG above Road/Wheelbase of Vehicle))*100
%AS = (tan(ΦR)/(h/b))*100
This formula uses 1 Functions, 4 Variables
Functions Used
tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
Variables Used
%Anti Squat - %Anti Squat is the percent amount of compression or vertical displacement of the rear wheels due to the acceleration of the car.
Angle between IC and Ground - (Measured in Radian) - Angle between IC and Ground is the angle made between the instantaneous center line and the ground.
Height of CG above Road - (Measured in Meter) - Height of CG above Road is defined as the height of vehicle's centre of gravity above road surface.
Wheelbase of Vehicle - (Measured in Meter) - Wheelbase of Vehicle is the center distance between the front and the rear axle of the vehicle.
STEP 1: Convert Input(s) to Base Unit
Angle between IC and Ground: 18.43 Degree --> 0.321664181142494 Radian (Check conversion here)
Height of CG above Road: 10000 Millimeter --> 10 Meter (Check conversion here)
Wheelbase of Vehicle: 1350 Millimeter --> 1.35 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
%AS = (tan(ΦR)/(h/b))*100 --> (tan(0.321664181142494)/(10/1.35))*100
Evaluating ... ...
%AS = 4.49870443848518
STEP 3: Convert Result to Output's Unit
4.49870443848518 --> No Conversion Required
FINAL ANSWER
4.49870443848518 4.498704 <-- %Anti Squat
(Calculation completed in 00.004 seconds)

13 Anti Geometry of Independent Suspension Calculators

Wheelbase of Vehicle from Percentage Anti Dive
Go Wheelbase of Vehicle = Percentage Anti Dive Front/((Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road))
Height of Centre of Gravity from Road Surface from Percentage Anti Dive
Go Height of CG above Road = ((Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)*Wheelbase of Vehicle)/Percentage Anti Dive Front
Percentage Front Braking given Percentage Anti Dive
Go Percentage Front Braking = Percentage Anti Dive Front/((Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road/Wheelbase of Vehicle))
Percentage Anti Dive on Front
Go Percentage Anti Dive Front = (Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road/Wheelbase of Vehicle)
Wheelbase of Vehicle from Percentage Anti Lift
Go Wheelbase of Vehicle = Percentage Anti Lift/((Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road))
Percentage Anti Lift
Go Percentage Anti Lift = (Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road/Wheelbase of Vehicle)
Height of Centre of Gravity from Road Surface from Percentage Anti Lift
Go Height of CG above Road = ((Percentage Rear Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)*Wheelbase of Vehicle)/Percentage Anti Lift
Percentage Rear Braking given Percentage Anti Lift
Go Percentage Rear Braking = Percentage Anti Lift/((Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road/Wheelbase of Vehicle))
Percent Anti Squat
Go %Anti Squat = (tan(Angle between IC and Ground)/(Height of CG above Road/Wheelbase of Vehicle))*100
Angle between IC and Ground
Go Angle between IC and Ground = atan(Side View Swing Arm Height/Side View Swing Arm Length)
Front View Swing Arm
Go Front View Swing Arm = (Track Width of Vehicle/2)/(1-Roll Camber)
Camber Change Rate
Go Camber Change Rate = atan(1/Front View Swing Arm)
Roll Camber
Go Roll Camber = Camber Angle/Roll Angle

Percent Anti Squat Formula

%Anti Squat = (tan(Angle between IC and Ground)/(Height of CG above Road/Wheelbase of Vehicle))*100
%AS = (tan(ΦR)/(h/b))*100

What is % anti-squat?

Anti-squat geometry is a function of the control arm geometry at the rear wheels. The amount of anti squat present is determined by a few factors such as the side view swing arm length and height, wheelbase and centre of gravity height.
