Embodiment Construction

[0043] The present invention will be further described below with reference to the accompanying drawings.

[0044] combine Figure 1 to Figure 3, The present invention proposes a motion-operated variable mass simulation device and a simulation method based on the device, which is composed of a support system frame 2 and a set of four rope traction systems. The support system frame 2 is constructed of profiles, which can be disassembled and moved as required. The simulated particle 5 is pulled by four ropes 4 in common, and all four ropes are connected to the winch 8 which is connected to the bottom DC motor 7 through the passing wheel 1 fixed on the frame. The DC motor with a photoelectric encoder performs Drive, force and acceleration sensors 3 for measuring the pull force F on the rope i and acceleration a i , this form of rope traction can meet the requirements of many working environments.

Abstract

The invention provides a variable mass simulation device for motion operation and a simulation method based on the device, belonging to the technical field of mass simulation, comprising a support system frame, a traction system, a simulated mass point and an operation end; To simulate the mass, the trainer can feel the corresponding load at the operating end; the basic method is to use the spatial convergence force system and the method of generalized inverse equations to solve the output tension of the rope based on the motion state of the particle at the operating end, and carry out each rope unit. Force closed loop control. The frame of the support system is constructed from profiles. The variable mass point to be simulated in the device is pulled by four co-located ropes. Each rope unit is connected to the winch on the motor through the pulley fixed on the frame after passing through the tension sensor and the acceleration sensor. The present invention can be used to simulate a mass point in space with variable mass, so as to realize some simulation training that ignores the volume but requires mass change.

Description

technical field [0001] The invention belongs to the technical field of mass simulation, and in particular relates to a variable mass simulation device for motion operation and a simulation method based on the device. Background technique [0002] Today, many work environments require different loads or masses, traditionally often accompanied by frequent replacement of equipment or volume issues. For example, with the development of science and changes in people's living environment, exercise has become people's needs. However, weight-bearing is often required during fitness, and frequent replacement of weight-bearing equipment has become a major problem; in space or other weightless environments, people will not be able to train; There are also some work environments that are not suitable for large volumes but require a certain mass or load, and people are often helpless. Design a variable-mass simulation device for motion operation, which can be used to carry out weight-be...
