Embodiment Construction
[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.
[0044] The inventors of the present invention consider that if the load simulation device is divided into compartments at different positions, and each compartment can independently adjust the center of mass and mass of the compartment, loads with different centers of mass and different masses can be simulated , thereby greatly saving the cost of the performance test of the vehicle.
[0045] Moreover, adjusting the centroid and mass of each compartment is more co...

The invention discloses a load simulation device and method. The load simulation method includes determining the volume of injecting liquid of every cylindrical section of the load simulation device according to the to-be-tested center of mass and mass of a vehicle; injecting liquid into a liquid injection hole in every cylindrical section of the load simulation device arranged on the chassis of the vehicle according to the determined volume of the injecting liquid of every cylindrical section; performing performance tests on the vehicle after injecting the liquid into the load simulation device. The load simulation device comprises a cylinder, two end plates and blocking plates; the cylinder is formed by at least two cylindrical sections connected in series, the top of every cylindrical section is provided with a liquid injection hole and a vent hole, and the bottom of every cylindrical section is provided with a mounting valve and a liquid discharge opening; the two end plates are respectively arranged at both ends of the cylinder for closing the cylinder; every block plate is arranged between adjacent cylindrical sections for separating chambers of the adjacent cylindrical sections. According to the load simulation device and method, the load simulation device can simulate the loads of different centers of mass and different masses, thereby greatly reducing the costs of the performance tests of the vehicle.
Description
technical field [0001] The invention relates to the field of launching devices, in particular to a load simulation device and a load simulation method. Background technique [0002] A vehicle generally consists of: a chassis and a load mounted on the chassis. [0003] Before the design of the vehicle is finalized, a load simulation device equal to the total mass of the load is usually installed on the prototype of the chassis to simulate the center of mass and weight of the vehicle to complete the vehicle under various working conditions such as loading, transportation, and unloading. performance test. At present, the existing load simulation device is usually a steel cylinder or a steel cylinder poured with cement, that is, an existing load simulation device can only simulate one centroid and one mass of the load. [0004] However, in order to better design the vehicle, it is necessary to perform performance tests on the vehicle loaded with loads of different centroids an...
