Problems solved by technology

[0004] At present, static tests and simulation analysis methods are mostly used for testing the different core components of the engine, that is, connecting rods and pistons at home and abroad. However, limited to the complex working environment of connecting rods and pistons, these methods cannot effectively simulate the real work of connecting rods and pistons. situation, resulting in a large difference between the test results and the actual data

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] see figure 1 , figure 1 The structure diagram of the device provided by the present invention. Such as figure 1 As shown, the device mainly includes: a piston temperature test module, a connecting rod temperature and strain test module, a data receiving module and a control center module.

[0027] In the present invention, the piston temperature testing module transmits the piston temperature by storing and forwarding the piston temperature data, specifically: collecting and storing the piston temperature data, and transmitting the stored piston temperature data to the connecting rod temperature and strain testing module;

[0028] Connecting rod temperature and strain test module, be used for and store connecting rod temperature and stra...

Abstract

The invention provides a joint testing method and device for different core components in an engine.According to the joint testing method and device, piston temperature data and connecting rod temperature and strain data of the same engine under a series of steady conditions can be measured through one time of testing, and joint testing of the core components, namely, a piston and a connecting rod in the engine is achieved, so that testing efficiency is improved, testing time is shortened, and testing cost is reduced.

Description

technical field [0001] This application relates to testing technology, in particular to a joint testing method and device for different core components in an engine. Background technique [0002] Small size, light weight and high power density are the development trends of automotive engines. Piston and connecting rod are different core components of the engine. As the power density of the engine increases, its mass will become lighter and smaller, and the mechanical load and thermal load it will bear will increase. [0003] At present, the test parameters of the connecting rod and piston in the working state of the engine are important parameters for studying the structure and performance of the core components of the engine. [0004] At present, static tests and simulation analysis methods are mostly used for testing the different core components of the engine, namely connecting rods and pistons at home and abroad. However, limited to the complex working environment of co...
