Abstract

The invention relates to a tangential acceleration elastic collision simulation device, which comprises a main body rack, a power device, a collision device, a speed regulation device and a test device, wherein the main body rack is fixed on a ground foundation and is formed by welding high-quality structural steel pipes; the power device is mounted on the upper top surface of the main body rack, a pendulum shaft I of the collision device is supported in the middle of the power device, a tire of the collision device is accelerated by the speed regulation device, the test device is fixed on a ground foundation and is positioned right below the main body rack, and when the tire impacts a sample, the test device collects an impact load. The mechanical control mode is adopted, the instantaneous collision load is obtained, the speed regulation device achieves real-time acceleration of tires with different heights through stepless speed change regulation, and real simulation in the laboratory environment is achieved.

Description

technical field [0001] The invention relates to the field of impact and collision simulation devices, in particular to a tangential acceleration elastic collision simulation device. Background technique [0002] At present, most impact testing machines are single-degree-of-freedom, and cannot perform rotational impact tests. When performing the impact test, the test sample can only be tilted at a certain angle, and the impact time calculated by this impact test is not instantaneous and has a certain time error; the invention provides a tangentially accelerated elastic collision simulation device using The mechanical control method realizes the acquisition of the instantaneous collision load, and the speed control device realizes the real-time acceleration of tires of different heights, realizing the real simulation in the laboratory environment. Contents of the invention [0003] The purpose of the present invention is to provide a tangential acceleration elastic collisio...
