Under the aim of finding effective rehabilitation solutions,the difference between the extents of fatigue of each muscle used in different motions are compared.Previous research suggested methods for estimating muscle torque and muscle tension on the basis of a musculoskeletal model.As a result,it has become possible to quantitatively identify the extent of fatigue in each muscle during motion.Therefore,to evaluate muscle fatigue more quantitatively,driving power and angular momentum are focused on.Based on the driving torque of joints and the muscle torque calculated by using a three-dimensional musculoskeletal model,a method for calculating the driving power of joints and the angular momentum of a muscle is proposed.This method is applied to analysis of different motions.Moreover,fatigue of muscles is quantitatively analyzed on the basis of driving power and angular momentum.

This research aims to quantify driver ride comfort due to changes in damper characteristics between comfort mode and sport mode,considering the vehicle’s inertial behavior.The comfort of riding in an automobile has been evaluated in recent years on the basis of a subjective sensory evaluation given by the driver.However,reflecting driving sensations in design work to improve ride comfort is abstract in nature and difficult to express theoretically.Therefore,we evaluated the human body’s effects while driving scientifically by quantifying the driver’s behavior while operating the steering wheel and the behavior of the automobile while in motion using physical quantities.To this end,we collected driver and vehicle data using amotion capture system and vehicle CAN and IMU sensors.We also constructed a three-dimensional musculoskeletal mathematical model to simulate driver movements and calculate the power and amount of energy per unit of time used for driving the joints and muscles of the human body.Here,we used comfort mode and sport mode to compare damper characteristics in terms of hardness.In comfort mode,damper characteristics are soft and steering stability is mild,but vibration from the road is not easily transmitted to the driver making for a lighter load on the driver.In sport mode,on the other hand,damper characteristics are hard and steering stability is comparatively better.Still,vibration from the road is easily transmitted to the driver,whichmakes it easy for a load to be placed on the driver.As a result of this comparison,it was found that a load was most likely to be applied to the driver’s neck.This result in relation to the neck joint can therefore be treated as an objective measure for quantifying ride comfort.

Quantifying Roll Feel of a Car by Using a Musculoskeletal Mathematical Model

Computer Modeling in Engineering & Sciences 2019年第3期118卷 493-507页

Primary purpose of this research is to create a three-dimensional musculoskeletal mathematical model of a driver of a car using a motion capture system.The model is then used in an analysis of drive torque around joints and attached muscles as a vehicle travels in different travel modes and damping force settings to examine‘burdens’for the driver.Previous studies proposed a method of quantifying the degree of musculoskeletal load in simple human motion from the changes in drive torque around joints and attached muscles.However,examination of the level of burdens for the driver while driving using this method does not seem to exist.Especially within the scope of evaluating different travel modes and dampers,there is no other study.Results of this study are hence a valuable new perspective on quantitative analysis of the burdens for the driver’s joints and muscles depending on the different settings of travel modes and dampers.
