Abstract

The invention relates to a camshaft parameter inspection method and device, computer equipment and a storage medium. The camshaft parameter inspection method comprises the following steps: acquiring the following electronic cam parameters: a parameter y0, a parameter v0, a parameter a0, a parameter t0, a parameter y1, a parameter v1, a parameter a1 and a parameter t1; substituting the parameters of the electronic cam into a camshaft equation; acquiring camshaft parameters p, wherein the camshaft equation: y=p0+p1*t+p2*t2+p3*t3+p4*t4+p5*t5, and a camshaft primary derivation equation: v = y'= p1+ 2 * p2 * t + 3 * p3 * t2 + 4 * p4 * t3 + 5 * p5 * t4, and a camshaft secondary derivation equation is as follows: a = y''= 2 * p2 + 6 * p3 * t + 12 * p4 * t2 + 20 * p5 * t3; acquiring motion parameters simulated by the camshaft according to the camshaft equation, primary derivation of the camshaft equation and secondary derivation of the camshaft equation; detecting whether a preset motion parameter is consistent with the simulated motion parameter or not; and if the preset motion parameters are consistent with the simulated motion parameters, operating the equipment according to the presetmotion parameters. By adopting the camshaft parameter inspection method, normal operation of the camshaft can be ensured, and the operation safety and accuracy of the camshaft are improved.

Description

technical field [0001] The present application relates to the technical field of electronic cams, in particular to a camshaft parameter inspection method, device, computer equipment and storage medium. Background technique [0002] The electronic cam is composed of one or more segments of motion curves, and is widely used in the industrial field; while the electronic cam based on the quintic polynomial can ensure that the displacement, velocity, and acceleration are continuous in a single segment of motion, and can ensure that the gap between segments The acceleration is continuous and the motion is smooth, so the electronic cam based on the quintic polynomial has been widely used in various motion controls such as automobile manufacturing and robots. [0003] However, the electronic cam is a curve based on mathematics. It uses the functional relationship between variables to complete the interpolation. It has no physical meaning and does not consider the actual mechanical m...

Problems solved by technology

[0003] However, the electronic cam is a curve based on mathematics. It uses the functional relationship between variables to complete the interpolation. It has no physical meaning and does not consider the actual mechanical mechanism. The same curve may be used in this mechanical structure. , but changing the mechanical structure may not be able to use it. Forcible operation is easy to damage the equipment and even cause safety accidents
