Problems solved by technology

[0003] The distance between the pressure detection part and the part to be tested can only be adjusted in a small range by turning the screw rod in the existing joint surface stiffness test bench. Therefore, when measuring parts of different sizes, the existing test bench has a large limitations of use

Abstract

The invention relates to a joint surface stiffness test bench and a using method thereof. The joint surface stiffness test bench comprises a base, a part II placed on the base, and a part I placed onthe part II; a laser displacement sensor is mounted on the part II, a reflector is mounted on the part I, and a side plate is separately connected to the opposite side walls of the base; at least oneelongated hole is arranged on each side plate along the length direction; and fastening bolts correspondingly passes through each of the elongated holes and is connected to positioning screw holes provided on the base. The distance between a pressure detecting mechanism and a part to be tested can be flexibly adjusted in a wide range; therefore, the joint surface stiffness test bench is not limited by the size of the parts during use, and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of detection instruments, in particular to a joint surface stiffness test bench and a method for using the same. Background technique [0002] There are a large number of joint surfaces in complex mechanical systems such as machine tools, gas turbines, and automobile engines, which destroy the continuity of the mechanical system structure and affect the overall performance of the mechanical system to a large extent. The connection characteristics of the joint surface present a certain degree of nonlinearity, and introducing the characteristic parameter model of the joint surface into the modeling process of the whole system can effectively improve the performance prediction ability of the whole machine in the product design stage. [0003] The distance between the pressure detection part and the part to be tested can only be adjusted in a small range by rotating the screw rod in the existing joint surface st...
