[0052] The present application is further described in detail below in conjunction with the accompanying drawings.
[0053] In one embodiment, if Figure 1 As shown, the present application discloses a rope stretching tension control method based on a tension meter, which specifically includes the following steps:
[0054] S10: Continuously pressurize the rope to be tested, and obtain the tensile transient tension and tensile critical tension of the rope to be tested through a tension meter.
[0055] Specifically, the rope to be tested is continuously pressurized, and the tensile transient tension and tensile critical tension of the rope to be tested under the continuous pressurization state are collected by a tension meter, wherein the tensile transient tension is the tensile tension value when the rope begins to generate internal stress, and the tensile critical tension is the tensile tension when the rope reaches a single strand break.
[0056] S20: Obtain the change in the stretching amount of the rope to be tested during the continuous pressurization process, and analyze the tensile change relationship between the pressurized load and the tensile tension of the rope to be tested in combination with the corresponding tensile transient tension and the tensile critical tension.
[0057] Specifically, Figure 2 As shown, step S20 includes:
[0058] S201: According to the stretching variation curve and the stretching transient tension and the stretching critical tension in the stretching process, the stretching tension of the rope to be tested is processed in stages to obtain multi-stage stretching variation parameters of the rope to be tested.
[0059] Specifically, the stretching tension is divided into stages by combining the stretching transient tension and the stretching critical tension in the stretching process with the stretching change curve. For example, the stretching tension data before the stretching transient tension is divided into the first order, the stretching tension data between the stretching transient tension and the stretching critical tension is divided into the first order, and the stretching tension data after the stretching critical tension is divided into the first order. The rope stretching tension change trend in each stretching stage is the same, thereby obtaining multi-order stretching change parameters of the rope to be tested.
[0060] S202: According to the multi-order stretching variation parameters, the stretching variation in each stretching stage is independently analyzed to obtain the stretching variation relationship between the compressive load and the stretching tension of the rope to be tested.
[0061] Specifically, according to the multi-section stretching change parameters, the stretching change in each stretching stage is analyzed independently, such as analyzing the stretching tension change trend of the corresponding stage according to the stretching tension value and loading pressure of each stretching stage, so as to obtain the stretching change relationship between the pressurized load and the stretching tension of the rope to be tested.
[0062] S30: Analyze the dynamic deformation degree of the rope to be tested according to the tensile change relationship, and build a rope tension control model for analyzing the tensile tension of the rope to be tested in combination with the static deformation degree under constant pressure.
[0063] Specifically, Figure 3 As shown, step S30 includes:
[0064] S301: Analyze the rope deformation degree of the rope to be tested under continuous pressure according to the tensile change relationship to obtain dynamic deformation data of the rope to be tested.
[0065] Specifically, the deformation degree of the rope to be tested under continuous pressure is analyzed according to the tensile change relationship, such as the change in rope elongation caused by the change in internal stress of the rope when the same pressure is continuously superimposed, thereby obtaining the dynamic deformation data of the rope to be tested.
[0066] S302: randomly selecting a plurality of load pressure values between the tensile transient tension and the tensile critical tension as a control group, applying a constant pressure to the rope to be tested, and obtaining static deformation data of the rope to be tested under the constant pressure.
[0067] Specifically, a plurality of load pressure values are randomly selected between the tensile transient tension and the tensile critical tension as a control group, and the selected load pressure value is used as the applied pressure. A constant pressure is applied to the rope to be tested within a certain period of time, and the rope tension change under constant pressure is detected by a tension meter, thereby obtaining the static deformation data of the rope to be tested under constant pressure.
[0068] S303: Associating the dynamic deformation data with the static deformation data, jointly analyzing the tensile tension of the rope to be tested, and constructing a rope tension control model for the rope to be tested according to the analysis result.
[0069] Specifically, taking the magnitude of applied pressure as the correlation point, the dynamic deformation data is correlated with the static deformation data, and the tensile tension of the rope to be tested is jointly analyzed through the correlated data. The dynamic deformation data is compensated for the tensile tension with the static deformation data, thereby obtaining the tensile tension change of the rope under different tensile states, and then constructing a rope tension control model for the rope to be tested.
[0070] In this embodiment, the rope tension variation relationship in the rope tension control model is expressed by formula (1), and formula (1) is as follows:
[0071]
[0072] in, represents the tensile tension control parameter of the rope to be tested, σ(nF) represents the dynamic deformation of the rope under the action of the nth pressure F, Indicates the degree of dynamic deformation of the rope. It represents the static deformation degree of the rope, K represents the influence coefficient of the rope material on the tensile tension, t represents the continuous stretching time under constant pressure F, t0 represents the stretching time to reach the critical tensile tension under constant pressure F, and σ(t) represents the static deformation of the rope when the constant pressure is maintained for t time.
[0073] S40: The actual hanging load of the rope to be tested is obtained and input into the rope tension control model to analyze the actual deformation of the current hanging load, and the tensile tension of the rope to be tested is adjusted and controlled according to the analysis result.
[0074] Specifically, Figure 4 As shown, step S40 includes:
[0075] S401: Analyze the actual deformation of the rope under the current hanging load through the rope tension control model, and determine whether the actual deformation of the rope reaches the rope breaking tension in combination with the preset rope breaking threshold of the rope.
[0076] Specifically, the actual hanging load value of the rope to be tested is input into the rope tension control model, and the actual deformation of the rope under the current hanging load is analyzed by the rope tension control model, and compared with the preset rope breaking threshold of the rope, and whether the actual deformation of the rope reaches the rope breaking tension is judged according to the comparison result, wherein the rope breaking threshold can be obtained by analyzing the factory setting parameters of the rope, and can also be obtained by tension testing the ropes of the same batch, and the pressure value when pressure is applied to the rope to cause the rope to break is the rope breaking threshold.
[0077] S402: According to the rope breakage judgment result, when the actual deformation of the rope does not reach the rope breaking tension, the tensile tension of the rope to be tested is adjusted.
[0078] Specifically, according to the rope break judgment result, when the actual deformation of the rope does not reach the rope breaking tension, that is, the mounting load pressure corresponding to the actual deformation of the rope does not reach the rope breaking threshold, the tensile tension of the rope to be tested is adjusted to match the real-time mounting load.
[0079] S403: When the actual deformation of the rope reaches the breaking tension of the rope, the load sharing of the hanging load of the rope to be tested is adjusted in combination with adjacent ropes.
[0080] Specifically, when the actual deformation of the rope reaches the breaking tension of the rope, the load of the rope to be tested is shared by combining with adjacent ropes, such as hanging the cargo on the rope to be tested and the adjacent ropes at the same time, so that the mounting load of the rope to be tested is shared by the adjacent ropes.
