Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] see figure 1 , a seat fatigue test device provided by the present invention is used for carrying out fatigue tests on various seats including subway seats, and specifically includes a fixture 1 of a hollow frame structure, and a plurality of Seat 10 requiring fatigue testing. The supporting structure of the fixture 1 can well match the structure of multiple seats (such as six subway seats).

[0024] Specifically, each seat 10 includes a seat cushion 11 and a backrest 12, the backrest 11 is vertically fixedly connected to the left end of the seat cushion 11, the left end of the clamp 1 has a seat mounting plate 20, and the backrest 11 It is fixedly connected with the right side wall of the seat mounting plate 20, thereby ensuring the...

Abstract

The invention discloses a seat fatigue testing device which comprises a clamp. Multiple seats are installed in the clamp. Each seat comprises a cushion and a backrest, the backrest is vertically and fixedly connected to the left end of the cushion. An air cylinder mounting rack is arranged the right upper portion of the clamp and is located on the right side of the seats, a first air cylinder is installed at the positions, corresponding to the backrests, of the lower portion of the left side wall of the air cylinder mounting rack respectively, and a second air cylinder is installed at the positions, corresponding to the cushions, of the left end of the bottom surface of the air cylinder mounting rack. The left end of each first air cylinder is in linkage connection with the corresponding backrest. The bottom end of each second air cylinder is in linkage connection with the corresponding cushion. Each first air cylinder and each second air cylinder are respectively connected with an air source through a magnetic valve and a pressure regulating valve sequentially. The seat fatigue testing device can simply and reliably conduct fatigue testing on various seats including metro seats and meets the fatigue testing demands for multiple load modes, different load sizes and different load frequencies.

Description

technical field [0001] The invention relates to the field of fatigue test technology, in particular to a seat fatigue test device. Background technique [0002] At present, the fatigue test device is used to evaluate the service life and safety factor of the seat, and it is an indispensable test and detection device to ensure the safe and reliable operation of the vehicle on which the seat is installed. Most of the fatigue test devices are designed for car seats and are limited to single or double seats. [0003] In recent years, due to the rapid development of the subway industry, all kinds of customers have considered the comfort, safety and service life of subway seats much higher than in the early days; the particularity of subway seats includes 6 people There are too many seats or seats for 8 people. In this context, how to effectively evaluate the durability and service life of subway seats is particularly important. [0004] Therefore, there is an urgent need to dev...
