Description
Technical field
The present invention relates to a kind of human body limb force exerting tester, have in the fields such as Ergonomic Assessment of somatometry, task design and analysis, product or system widely and use.
Background technology
Although the development of economic technology has brought the automatization of task, manual operations critical role still in most industries.Because " human oriented design " theory of task hand-manipulated is rooted in the hearts of the people, need to be to its analysis of getting married property and assessment.Therefore, for guaranteeing economical sustainable development and occupational safety, the occupational health risk assessment that is caused by manual operations has become the major issue that the Government and enterprise management level need to be researched and solved.
According to analysis, task hand-manipulated can be divided into types such as recommending, put down, push away, draw, hold, break off with the fingers and thumb, revolve/twist, refer to kneading kind material in commercial production.Studies show that it is the major reason that causes worker back illness.For example, be engaged in for a long time the misery that the industrial workers who recommends operation about 80% can be subjected to back pain (LoW back pain, LBP).In the U.S., be used for the expense of LBP up to multi-billion dollar, be the main cause of developed country's occupational health damage reparations.In addition, musculoskeletal disease is the class frequently-occurring disease relevant with occupation, and it has influence on professional populations more than half, is the main cause of industrial workers's absence from duty.According to statistics, this type of illness of about 30% is owing to manual operations causes.Therefore, the maximum static muscular strength of the safety range of manual operations load and human body limb has just become a key areas of task ergonomic design and analysis and research since 20 century 70s.For example, U.S.'s professional safety and health institute (NIOSH) and Occupational Health NAB National Association 0f Broadcasters of government (ACGIH) had once worked out the NIOSH equation of manual lifting weight and the limit value of occupational safety; 1987, Germany promulgated " human body strength-maximum static action force standard " (DIN 33411-4).
Because ergonomics is about understanding interactive subject between other key element of people and system, also be that utility theory, principle, data and method design, so that people's health and entire system efficient reach optimum a special kind of skill, its core is safety, healthy, efficient.Therefore, it can play very important effect to the employment injuries that prevents task hand-manipulated.But this needs the anthropometric data of certain sample size to support.Because the difference of the aspects such as race, body dimension, we can not directly quote the related data of American-European countries.Need specifically to measure professional population thrust, pulling force that China is engaged in task hand-manipulated, recommend, press down, inside/outside is broken power off with the fingers and thumb, pedal, refer to pinch, finger pressure, the limbs application of force value such as revolve/twist, and carry out statistical analysis, be intended to for task ergonomic design, select the operator, work out occupational safety standard etc. reference frame is provided.At present, domestic research in this regard is still at the early-stage, and the data type of concrete test comprises following several:
1 push/pull power, testee in the situation of taking standing position or sitting posture position, the strength of push/pull before one hand/both hands level.
2 recommend/downforce, and testee is in the situation of taking standing position or sitting posture position, and singlehanded forearm is in level, and keeps certain angle with upper arm, in horizontal plane, upwards recommend in the vertical direction or to the strength that presses down.
3 inside/outsides are broken power off with the fingers and thumb, and testee is in the situation of taking standing position or sitting posture position, and singlehanded forearm is in level, and keeps certain angle with upper arm, in horizontal plane, in horizontal plane, to the strength of breaking off with the fingers and thumb in health inboard or the outside.
4 fingers are pinched power, and testee is taked the sitting posture position, the strength that singlehanded thumb and forefinger are mediated.
5 finger pressure power, testee is taked the sitting posture position, the strength that singlehanded thumb or forefinger finger tip face press down.
6 screw power, and testee is in the situation of taking standing position or sitting posture position, and one hand is held operational objectives, are clockwise or the strength of counterclockwise rotating.
7 pedal powers, testee are taked the sitting posture position, shank and thigh at an angle, the strength that instep is pedaled outward.
Ergonomics research at present relevant human strength data test is concluded, can find that a common recognition is, the science of operator's strength test data and reliability are to determine that product or system's getting married property level design very crucial, but testing equipment still is mechanical pointer ergometer or simple digital display equipment, exists the subject matter that needs to solve to be:
1 strength test data can not be carried out curve display, and can not keep continuously long complete test data.
2 for different strength types, need ergometer of different nature, in actual test job, if the strength type greater than more than 3 kinds the time, it is more time-consuming to change instrument.
3 need to be by other statistical analysis softwares such as SPSS for the measurement data that obtains, the Treatment Analysis software that does not carry.
In a word, operator's application of force characteristic causes physical fatigue or the aspects such as occupation is sick and wounded, prescribed product or system's Human Machine Interface have a very important role in definite operation routine, prevention.For making things convenient for test operation, data acquisition and analysis, need to test simultaneously the testing equipment of different operating strength type, to improve testing research efficient with scientific.
Summary of the invention
The objective of the invention is when overcoming the test of the present testee limbs application of force, test data can not be visual, data can not process in real time that the testing efficiency that causes with analysis and frequent test instrunment reduces and the problem such as operation, provide a kind of and can test, shown and singlehanded push/pull power of its upper limb when analyzing testee and being in standing position or sitting posture, recommend/downforce, inside/outside is broken power off with the fingers and thumb, refer to the power of pinching, finger pressure power, screw the integrated instrument of the pedal power under power and the sitting posture state, is used for the Changing Pattern of research testee limbs application of force characteristic.
A kind of human body limb force exerting tester comprises that integration test and analysis meter, inside/outside break power test suite and pedal power test suite off with the fingers and thumb;
Integration test and analysis meter are used for selecting limbs application of force type, show selection mode and gather each limbs application of force data signal and analyze and process, test simultaneously testee vertical/push/pull power during the sitting posture state, recommend/downforce, refer to the power of pinching, finger pressure power and the application of force characteristic of screwing power, and provide the fixing hole of instrument; Inside/outside is broken the power test suite off with the fingers and thumb, and when being used for that the singlehanded forearm of testee becomes the angle of regulation with upper arm under standing position/sitting posture state, test is broken power in the health inboard off with the fingers and thumb or to the outer power of breaking off with the fingers and thumb in the health outside, and with the data signal biography of testing to integration test and analysis meter; The pedal power test suite is used for test testee sitting posture state and places an order the thigh of lower limb when presenting the angle of regulation with seat, thigh and shank, the power of pedaling of testing single lower limb, and with the data signal biography of testing to integration test and analysis meter.
The invention has the advantages that:
