Rigidity experiment bench equipment for opening and closing part

The invention relates to experiment bench equipment used for detecting the rigidity of a vehicle opening and closing part. The experiment bench equipment comprises a base assembly, a left oscillating arm assembly, a right oscillating arm assembly, a left moving support seat assembly, a right moving support seat assembly, a left fixing support seat assembly, a right fixing support seat assembly and a free beam assembly. The experiment bench equipment is characterized in that the left fixing support seat assembly and the right fixing support seat assembly are fixedly arranged on the base assembly by bolts, and the free beam assembly is matched with a lifting platform on the left fixing support seat assembly and the right fixing support seat assembly through circular cylinders on both ends of a cross beam. According to the experiment bench equipment disclosed by the invention, all rigidity experiments of the opening and closing part are integrated on one bench, and special experiment bench equipment can be manufactured. The experiment bench equipment can adapt to opening and closing parts of different vehicle types, different sizes and different classes, additionally, the experiment installation state of an experiment part is kept consistent with the assembly state on a real vehicle body, the gravity effect is eliminated, and the experiment schedule is increased.
