Abstract

The invention discloses a test device for simulating different vehicle loads and measuring the power generation performance of a piezoelectric device under different vehicle loads based on a triaxial apparatus. The test device comprises a triaxial apparatus body and a pressure chamber arranged in the triaxial apparatus body. The pressure chamber is provided with a base, a soil sample device and a top cap arranged at the top of the soil sample device. The soil sample device comprises a rubber membrane and a soil sample arranged in the rubber membrane. The triaxial apparatus body is provided with a loading rod corresponding to the top cap, the bottom end of the loading rod is in contact with the top cap, and the upper end of the loading rod is provided with a loading system. A piezoelectric device is arranged in the soil sample device, the piezoelectric device is connected with an oscilloscope through an output wire, and the oscilloscope is located outside the triaxial apparatus body. A protection sheet is arranged on the outer side wall of the top cap, and a first wire clamping groove is formed in the protection sheet. An output wire of the piezoelectric device is sequentially clamped into the first wire clamping groove and penetrate through the triaxial apparatus body to be connected with the oscilloscope. The test device can simulate different vehicle loads, and can accurately measure the power generation performance of each vehicle load on the piezoelectric device.

Description

technical field [0001] The invention relates to a test device for measuring the power generation performance of a piezoelectric device under simulated different vehicle loads based on a triaxial instrument. Background technique [0002] As an important energy conversion technology, piezoelectric power generation technology has been widely used in real life, and is gradually being used in the field of road traffic. Under the action of vehicle traffic load, the mechanical energy of the vehicle is converted into electrical energy. In general, piezoelectric ceramics are placed in the roadbed during the test stage, and the vehicle load conditions are simulated on the roadbed, and the power generation performance of piezoelectric ceramics under each different vehicle load cannot be accurately obtained. In the piezoelectric test, the engineering quantity of the test is large and the cost is high. Contents of the invention [0003] The technical problem to be solved by the prese...
