Abstract

The invention discloses a dynamic and static mechanics comprehensive test bench, which relates to mechanics experimental equipment. Nowadays the mechanics test bench in the market has the disadvantages of single function, inconvenient operation, big size of the equipment and high price. A pure beam bending device, a composite beam bending device, a cylinder crankling device, a dynamic beam device, an equal strengthen beam device, a stretching and compressing device and a sinker rod are arranged on a main bench frame; the pure beam bending device, the composite beam bending device, the equal strengthen beam device, the cylinder crankling device and the stretching and compressing device respectively adopt a hand operated helical wheel to load, a sensor to measure the power, and transfer a load through a combined type lever power transmission system; the dynamic beam device uses a motor with an eccentric wheel to vibrate hardly; an interface board which is connected with the lead wire ofa strain meter is arranged on the bench surface. The invention has the functions of combining and arranging various experiments of the basic mechanics and skill training of various basic experiments.The invention has the advantages that the comprehensive function is powerful, the cost performance ratio is high, the structure is compact, and the operation is convenient.

Description

technical field [0001] The invention relates to mechanical experiment equipment, which is a comprehensive test bench for experimental teaching of courses such as basic mechanics in colleges and universities. Background technique [0002] At present, higher education pays attention to the cultivation of students' practical ability and innovative spirit, and experimental equipment with good functions is needed in the teaching of mechanics experiments. The mechanical test benches currently on the market, on the one hand, have single functions, no dynamic experiments, and are inconvenient to operate and use. On the other hand, the equipment is bulky and the purchase cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a dynamic and static mechanics comprehensive test bench for mechanics experiment teaching, which has strong comprehensive functions and low cost performance High, compact structure and easy operation. [0004] The ...
