54results about How to "Simplify the tuning process" patented technology

A method of making a tuning map for a vehicle device includes deriving performance parameters of the vehicle device in a new vehicle and setting a target tuning performance. A pre-tuning map is established by building an interpretation model of the new vehicle including an interpretation model and a control model of the vehicle device, and tuning parameters, which satisfy the target tuning performance, are set using the performance parameters through interpretation of the models. The pre-tuning map is applied to a control logic of the vehicle device for an actual vehicle which includes the vehicle device mounted therein, and the actual vehicle tuning is performed. Whether actual vehicle performance satisfy a preset target performance after tuning the actual vehicle is evaluated, and the tuning map is finalized when the target tuning performance is satisfied.

The invention relates to a suspension stiffness adjustable mechanism. The suspension stiffness adjustable mechanism comprises an upper cover plate, a fixing bolt, a rubber body, a lower bottom plate and an adjusting mechanism, wherein the fixing bolt is riveted to the upper cover plate; the upper cover plate, the rubber body and the lower bottom plate are vulcanized into an integrated structure; the adjusting mechanism and the rubber body are vulcanized into an integrated structure. According to the technical scheme provided by the invention, the adjusting mechanism is planted into the rubber body, so that a complicated adjustment process is simplified and refined in a product development process under a rubber stiffness adjusting link. Experiment resources are continuously run and arrangement work before experiments does not need to be repeatedly done; a complicated assembling, adjusting, mounting and dismounting link in the process is omitted and the whole process is finished under a whole vehicle assembling state of special rubber bodies.

The invention belongs to the technical field of chemical energy instruments, and specifically provides a three-point adjustment method for a regulating valve with an electric valve positioner, which connects the regulating valve to be calibrated with a signal generator; in the regulating valve to be calibrated, an input signal m 1 , record the corresponding valve position display value n 1 ;input signal m 2 , record m 2 Corresponding valve position display value n 2 ; compute n 2 and n 1 the difference, compare the difference with 50% of the total stroke; adjust the range knob according to the comparison result until the difference is equal to 50% of the total stroke; input signal m 3 , adjust the valve position display value to 50% of the total stroke position through the zero adjustment knob, and the adjustment is completed; it solves the cumbersome adjustment process of the five-point method, the adjustment time is long, the error in the starting point confirmation process is large, and the maximum defect zero point is difficult If it is accurate, the operator cannot understand the essence and principle of the adjustment. The invention realizes three-point adjustment, the adjustment process is simple, the principle is clear at a glance, the efficiency is high, the accuracy rate is high, and there is no error, and the operator can easily grasp and understand the adjustment. School principles.
