Motorcycle Simulator Dual-Movement Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle simulation apparatuses have limitations in replicating realistic driving stresses and movements, failing to adequately subject drivers to the inertial environments experienced during actual motorcycle riding, which restricts the fidelity of simulation and increases the risk of injury.
Innovation Solution
The apparatus combines a first movement unit with linear actuators to simulate roll, pitch, and yaw, and a second movement unit with wearable cables and drive members to induce realistic acceleration and deceleration forces on the driver, allowing for a synergistic combination of stresses and increased range of motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hexapod structure with linear actuators is used to move the support body, then roll, pitch and yaw can be simulated, but the range of movement is limited and insufficient stresses are applied to the driver
Solution Approach 1:
The movement unit is divided into two independent units: a first movement unit (hexapod structure) that moves the support body, and a second movement unit that directly applies stresses to the driver. This segmentation allows each unit to perform its specific function optimally, with the second unit providing the necessary stresses without being constrained by the movement capabilities of the first unit.
Solution Approach 2:
The driver becomes an intermediary element between the two movement units. The second movement unit applies forces through the driver, who is seated on the support body moved by the first unit. This allows the stresses to be transmitted directly to the driver while maintaining the independence of the two movement systems.
2Reliability
If the second movement unit is integral with the support body, then driving stresses can be applied, but the forces are dependent on support body movements and the simulation is not realistic
Solution Approach 1:
The system separates the second movement unit from the support body, making them independent components. The second movement unit is connected to the support base rather than the support body, allowing it to generate forces independently of the support body's position and orientation. This enables realistic stress application regardless of the support body's movement state.
3Reliability
If traditional simulation apparatuses are used, then basic motorcycle movements can be simulated, but the driver is not exposed to sufficient accelerations and the inertial environment is not realistically reproduced
Solution Approach 1:
The driver serves as the intermediary through which the second movement unit applies inertial stresses. By directly acting on the driver rather than only moving the support body, the system can expose the driver to sustained accelerations and realistically reproduce the inertial environment of actual motorcycle riding for extended periods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This combination enhances the realism of the driving simulation, allowing for more extensive and safe exposure to accelerations, thereby providing a more faithful reproduction of the inertial environment, improving simulation efficiency and safety.
