ChassisSim isn't just another race car simulation package that only produces lap time. ChassisSim has a complete range of toolboxes that can accurately test every component of the car that affects its performance: springs. anti roll bars, shock absorbers, ride heights, gear ratios, engine power, wings etc.
The toolboxes can be added to ChassisSim Standard only (ChassisSim Elite comes with the full set).
7 Post Rig Analysis/Bode Plot
This runs your car as if it was on a full 7 post rig analysis machine. It is the ideal tool to review the frequency response of your car. It then outputs the results to a data file that can be viewed in Excel or Matlab. Price: $POA
Auto Bump Generation
By using logged data and the vehicle setup, ChassisSim can calculate the bump profile of the circuit. The bump profile is how the road surface varies throughout the circuit. Price: $POA
Aero Modelling
This Toolbox allows ChassisSim to produce logs of Front and Rear Ride Height vs Downforce, Drag and Aero Balance. Simply put it is a powerful tool that allows you to determine the aeromap of the car. Price: $POA
Tyre Force Modelling
This will produce the maximum Tyre Force vs Load characteristics for the front and rear tyres, based on the vehicle setup and logged data. This is a centre piece for determing the tyre models for your racecar. Price: $POA
Aero Setup Optimisation
Given upper and lower limits of downforce and aero balance, ChassisSim will autonomously determine the best possible selection of downforce and aero distribution for a given car and circuit. Price: $POA
Mechanical Setup Optimisation
Given the upper and lower limits of front and rear springs, and front and rear roll bars, ChassisSim will autonomously determine the best possible selection of front and rear springs, plus front and rear roll bars for a given car and circuit. Price: $POA
Damper Setup Optimisation
Given the upper and lower limits of front and rear low speed and high speed damping front and rear, ChassisSim will determine the optimum damper curves front and rear for a given car and circuit. Price: $POA
Terminology:
A arm Vee shaped suspension arm attached to chasis & upright of car
Anti dive the use use of mechanical means to reduce the amount the front of the car dives under brakes
Anti roll bar A rod or tube linked to the suspension that resists the rolling of the car. The bar twists as the car rolls
Anti squat - Is the use use of mechanical means to reduce the amount the rear of the car squats under acceleration
Bump the term used to describe the force required to compress ashock absorber
Camber The angle of the wheel as seen from front on.
Castor the amount the top pivit of the upright leans back in relation to the bottom pivot
Centre of gravity The point at which the car is perfectly balanced
Damper / shock absorber Mechanical device to dampen (control) the natural oscillations of the spring
Droop the amount the wheels move down from ride height
Instant centre found by projecting a lines from the suspension arms until they meet
Instantaneous roll centre the roll centre when the car instant the car is in its dynamic state.
Motion ratio the amount that the spring moves in relation to how far the wheel moves
Pitch the rotation of the car either under acceleration or braking
Rebound the force resisting the extension of a damper / shock absorber
Ride height height of certain designated points on a chassis from the ground
Roll axis the line joining the front & roll centres
Roll centre Geometric point about which the vehicle rotates when cornering
Spring rate the load required to move the spring a certain distance ie newtons per millimetre
Toe In When a pair of wheels are closer at the front than the rear
Toe out When a pair of wheels are closer at rear than the front
Wheel rate the actual spring that the tyre sees after the effects of the motion ratio are taken into account
Wishbone Vee shaped suspension arm attached to chasis & upright of car
