Abstract:
1. A testing device for evaluating performance of closure of a vehicle door, comprising: a speed calculating part for calculating a speed of the vehicle door during a motion of the door relative to a main body of a vehicle, wherein the door is a slide door which moves translationally relative to the main body of the vehicle; an analyzing part for analyzing behavior of the door by processing the speed changing in consequence of a closing motion of the door; a judging part for judging a state of closure of the door based on a result of the analysis obtained by the analyzing part; and an acceleration measuring part attached to the door and adapted to measure acceleration of the door during the translational motion of the door, wherein the speed calculating part calculates the speed of the door by subjecting the measured acceleration to time integration, and wherein the speed calculating part comprises:
