Motorcycle frame rigidity performance test device

Abstract

The invention discloses a motorcycle frame rigidity performance test device. The device comprises a pedestal. The pedestal is provided with a vertical pressure cylinder and a horizontal pressure cylinder respectively. Tail ends of the two pressure cylinders are connected with a vertical pressure sensor and a horizontal pressure sensor respectively. The other end of the vertical pressure sensor is connected with a rear pressure plate seat. The other end of the horizontal pressure sensor is connected with a horizontal slide carriage. A headstock rod support is fixed on the horizontal slide carriage. A headstock rod shaft, which is used to fix a front fork of a motorcycle frame, is installed on the headstock rod support. Side edges of the rear pressure plate seat and the horizontal slide carriage are provided with grating scale sliding plates. A left support seat and a right support seat, which are used to fix a rear fork, are fixedly arranged at a position which is close to a vertical rack on a horizontal rack of the pedestal. According to the invention, an actual road frame rigidity performance test before a new product is put in production can be abandoned. A structure is simple and reasonable. A demand for testing and evaluating frame intensity and rigidity performance during a development process of the motorcycle frame can be satisfied. By using the device of the invention, the new product can be rapidly made into markets.

Description

technical field [0001] The invention relates to a performance testing device, in particular to a motorcycle frame rigidity performance testing device for testing the strength or rigidity of a developed new motorcycle frame to ensure sufficient safety. Background technique [0002] The motorcycle frame is a large-scale force-bearing member with very strict requirements, and it must have sufficient strength and rigidity to ensure that the factory motorcycle has sufficient safety performance. Under the action of load, the frame must have sufficient static strength and fatigue strength. Static strength refers to the ability of the frame to resist permanent deformation when subjected to impact loads. Fatigue strength refers to the ability of the motorcycle to withstand alternating stress without fatigue cracks and fatigue fractures during driving. Practice has proved that the main damage form of the current motorcycle frame is fatigue damage. Generally, cracks are generated in ...

AI Technical Summary

Problems solved by technology

Practice has proved that the main damage form of the current motorcycle frame is fatigue damage. Generally, cracks are generated in local areas (welded joints), and then the cracks propagate to cause fracture.

The fatigue strength is not enough. After a period of use, serious accidents such as frame breakage and permanent deformation are prone to occur, which poses a serious threat to personal safety.

At present, the performance test of the newly developed motorcycle frame generally adopts the on-site test method. The on-site test can best verify the reliability of the product and is also the most reliable test method. The collection of on-site product data plays a pivotal role in the entire test. Therefore, before a new product is put into production, a road test of 6,000-10,000 kilometers is required. According to the requirements of relevant industries, this test needs to be tested on a certain proportion of road types. It will not only take at least three months, but also require A lot of financial and material resources have been invested; in addition, collecting on-site data is a challenging task. Corresponding managers organize and manage, so that more accurate data can be obtained

The traditional road test method is time-consuming, costly and labor-intensive, and it is not conducive to the rapid introduction of new products into the market
