Abstract :
A vehicular platform´s dynamical behavior is analyzed as a basis for designing a laboratory test apparatus and an associated 2-dimensional orthogonal stabilizer. The test track caused inclination in the front direction to vary from -6.5deg to 7.2deg and from -5.5deg to 5.0deg in the side direction. The maximum angular rate was 19.8 plusmn 0.1deg/s in the front direction within a bandwidth of 0-2.5 Hz and 14.4 plusmn 0.05deg/s in the side direction. The platform´s natural frequency in the front direction was found to be 0.8-1.0 Hz. In the side direction the most significant rate values appeared within 0-4 Hz but the natural frequency did not wake. Inclination measurements were based on sensor fusion where the basic model of stochastic Kalman filtering was applied
