The traditional elevator system has been applying enforced displacement excitation with a shaking table for its seismic resistant evaluation. Generally, the experiment of enforced displacement excitation requires a huge specific facility to shake a test body, so that such an excitation system is not suitable for ordinary experiments. In this paper, a new seismic resistant evaluation system is proposed, which is easy to use and adjustable to the actual elevator test facility. The proposed system installs several exciters in the car and they induce inertia force against the car. Therefore, the car excitation is realized by a compact system. As the system doesn't need any additional equipment in the elevator shaft, it is appropriate to do the excitation test in the existing test shaft. Several experiment results also show validity of the new excitation system.
