MotorSim 2 is an advanced performance calculator designed specifically for land vehicles, offering enthusiasts a detailed tool for understanding vehicle dynamics without the need for a driving game. This app focuses on simulating straight-line acceleration performance, providing a deep dive into the mechanics of vehicle propulsion.
With MotorSim 2, users can fine-tune a variety of technical specifications to see how these adjustments impact overall vehicle performance. The app features an interactive simulator equipped with a speedometer, rpm meter, throttle, brake, and gear shift options (both manual and automatic). It also includes a procedurally generated engine sound, not derived from samples, enhancing the realism of the simulation. Additionally, the app visually represents the vehicle's progress over a 1/4 mile track segment, allowing users to save a "ghost" or "shadow" of their settings. This feature enables later comparisons with different configurations, aiding in optimizing vehicle performance.
Configurable Vehicle Parameters
- Max Power: Set the maximum power output of the engine.
- Power Curve: Define the power curve point by point to customize engine behavior.
- Torque Curve: Automatically defined based on the power curve since power equals torque multiplied by rpm.
- Max Engine RPM: Specify the engine's ignition cutoff point.
- Gears Configuration: Adjust up to 10 gears for precise control over acceleration.
- Resistances: Input values for Cx (drag coefficient), frontal area, and rolling resistance coefficients to account for aerodynamic and frictional forces.
- Vehicle Weight: Modify the vehicle's total mass.
- Tyre Size: Change tyre dimensions to affect traction and rolling resistance.
- Shift Time: Set the duration for gear shifts to simulate transmission performance.
- Transmission Efficiency: Adjust the efficiency of the vehicle's transmission system.
Calculated Performance Parameters
- Maximum Speed: Determine the top speed achievable by the vehicle.
- Acceleration: Calculate times from 0 to 60 mph, 0 to 100 mph, 0 to 200 mph, 0 to 300 mph, and beyond.
- Additional Metrics: Utilize the interactive simulator to measure any other performance metrics you need.
MotorSim 2 is a powerful tool for anyone interested in the intricacies of vehicle performance, offering a comprehensive platform to experiment with and understand the impact of various technical configurations on land vehicles.
